They launched together in 1937 as a matched pair, and they open a line that runs, under one Precision designation after another, for the next forty-seven years. Every Rolex ever called a "Precision" Oyster traces back to these two references.

The 3003 and 3004 are the first Rolex Precision references. They launched together in 1937 as a matched pair, and they open a line that runs — under one Precision designation after another — for the next forty-seven years. Everything Rolex has ever called a “Precision” Oyster traces back to these two references. The automatic Oyster Perpetual had arrived in 1933 on the Bubbleback platform; the 3003 and 3004 established the parallel track — manual-wind Oyster, not chronometer-certified, sold at a lower price point, aimed at the buyer who wanted a waterproof Rolex without the rotor.
The antique-era timeline in ''The Vintage Rolex Field Manual'' sets the launch down precisely: "Launch of the Rolex Precision (refs. 3003 &amp; 3004) and Centergraph (ref. 3642)." Three references, one year, one entry. The Centergraph, a single-button Oyster chronograph, is the third child of 1937 and is addressed briefly below as a contemporary sister reference. The 3003 and 3004 are the focus here.

The differentiation between 3003 and 3004 at the parts-catalog level is not documented in surfaced sources. The Field Manual treats them as a pair. Dealer and auction listings for the specific numbers 3003 and 3004 are thin — both references surface more frequently in the broader context of the early Precision population than as numbered lots in their own right.

Rolex marked movement grades from the 1920s onward, and the system ran through three generations of names. The first was the Prima family — '''Prima''', '''Extra Prima''', '''Ultra Prima''' — documented by David Boettcher from Swiss trademark-register entries. Prima first appears in August 1923 as “Marconi Prima”; Ultra Prima registers December 1930 as a Wilsdorf coinage. Prima-grade was fifteen jewels, adjusted; Extra and Ultra Prima were eighteen jewels (fifteen plus two escape-wheel end-stones and a centre-wheel top bearing) and increasingly tightly regulated. The grades sat on the same underlying movement architecture; the difference was adjustment work, not additional components.
Rolex graded these early movements by regulation level rather than by radically different architecture. Prima, Extra Prima, and Ultra Prima indicate more about adjustment and finishing than about a different movement design.


By the mid-1930s the Prima names were giving way. The 3003 and 3004 dial carries the successor term: '''Precision'''. The same three-tier logic survives the rename — Precision, Extra Precision, Super Precision — and the pattern persists through the Cal. 1200 base era (1954–1984). Super Precision (Ultra Prima’s successor) denoted observatory-trial-grade accuracy. Precision, as used on the 3003 and 3004 dial, is the entry-level designation: a Rolex Oyster with an adjusted movement, manufactured and regulated to a published standard, but not submitted to chronometer certification.
By the mid-1930s the Prima names were giving way to Precision, Extra Precision, and Super Precision. The logic stayed the same: different regulation grades on broadly similar movement architecture, with Precision below full chronometer status.


This is the key distinction. The Precision line is not the Chronometer line. A Rolex buyer in 1937 choosing an Oyster Precision was choosing a waterproof, adjusted, manual-wind Oyster that did not carry the chronometer-certificate premium of the Oyster Perpetual Chronometer or the Oyster Chronometre. It was the same Oyster case, the same serious movement, and the same warranty against dust, water, and climate — minus the Neuchâtel or Kew certificate and the price that came with it.

The period-correct movement for the 3003 and 3004 is a 10½-ligne Hunter-type Rolex caliber — the same family that powered the mid-1930s manual Oysters across the catalog. Fifteen jewels on base-grade examples, seventeen on better ones. Monometallic balance with the Rolex Patent Superbalance, Breguet overcoil, straight-line lever escapement, rhodium-plated, adjusted in six positions for all climates. The Superbalance and six-position adjustment text appears on the movement itself — the same specifications Rolex had been putting on its Hunter-type manual Oysters since the late 1920s.

Cal. 700, the purpose-designed thin manual-wind Precision caliber, arrives in 1938 — a year after the 3003/3004 launch. Early 3003 and 3004 examples therefore sit just before the Cal. 700 transition, on the older 10½ Hunter base. Later production may carry Cal. 700 in the same cases; the transition is not cleanly documented in surfaced sources.

No shock protection. Incabloc and KIF arrive on Rolex calibers in the late 1940s with the A.296. The 3003 and 3004 movements predate that by more than a decade, and they should be treated as unprotected by modern standards.

Standard Oyster construction for the era: three-piece, threaded bezel, mid-case, and caseback, with the screw-down Oyster crown on its patented left-hand-thread-replacement dog-clutch design. Diameter typically falls in the 33–34 mm range — small by modern standards, conventional for a 1937 men’s Oyster. Lugs are soldered directly to the mid-case in the early-Oyster manner. Materials follow the usual mid-1930s Rolex range: stainless steel, 9ct yellow gold for the British market, higher-karat gold for other markets, rose gold examples in parallel.

Caseback signatures on Oysters of this period carry the familiar “Oyster Watch Co.” and patent-reference engravings. The reference number itself sits on the caseback interior in most cases, not on the outside.

The bezel is smooth and polished. Engine-turned bezels on Precision-line watches arrive later, on the mid-1940s and 1950s Speedking-family references.

“ROLEX OYSTER PRECISION” is the dial text — three lines, centered under 12. Layout is conventional for a 1937 Oyster: Arabic numerals or applied baton indices, sub-seconds at 6, restrained printing, no calendar aperture. Two-tone sector dials appear in period photography, consistent with the Art Deco dress-watch conventions of the late 1930s. Radium-luminous numerals turn up occasionally but are less common on Precision-line Oysters than on the sporting Oyster Perpetuals and Oyster Army references that follow.

The dial text is the primary identifier. A late-1930s Oyster dial reading “ROLEX OYSTER PRECISION” is, by definition, a Precision-line watch — and in 1937 the only references carrying that text are the 3003 and the 3004. Earlier Oysters carry “Rolex Oyster” without the Precision designation; later Precision references use the same three-line layout into the 1960s.

The Centergraph is a different animal — a single-button Oyster chronograph, center-seconds, with a 10½-ligne rhodium-plated movement, eighteen jewels, Superbalance, and a lever escapement. Production was tiny. Antiquorum’s 1996 catalog entry for the 3642 described the reference as “produced in stainless steel only, in less than 50 examples.” Names varied across the run — Zerograph and Centergraph were used interchangeably in period references, and the reference number also appears in some catalogs as 3462 (likely a transcription error for 3642).

The Centergraph does not share a platform with the 3003 and 3004. It is a chronograph; they are time-only Precisions. What they share is the 1937 launch year and the serious-movement specification — six-position adjustment, Superbalance, Breguet overcoil. In the Field Manual’s timeline they are the same entry. In the market they are not comparable: Centergraphs, when they surface, are five-figure rarities; Precisions of the 3003/3004 era are modest vintage Oysters.

The Precision designation outlives the 3003 and 3004 by nearly half a century. A short survey of what follows:
The Precision label does not stop with the 3003 and 3004. It continues through later small manual-wind Oysters, early automatics, and eventually the long Oyster Precision line of the second half of the century. The 3003 is simply one of the earliest clear starting points.
 
'''Ref 2595''' — Speedking Precision, roughly 1938–1941, 29–30 mm steel, eighteen-jewel Superbalance movement. Smaller case, same Precision logic applied to a sport-adjacent variant.
 
'''Ref 4220''' — Speedking Precision, 1941 into the early 1950s, 30 mm steel, Cal. 10½ Hunter or Cal. 700 or Cal. 710 depending on production year. California dials on 1941–1949 examples. The 4220 is where the Precision line most clearly crosses into collector attention today.
 
'''Ref 2764''' — Super Precision Bubbleback, 1937–1948. Same Precision three-tier logic applied to the automatic line — Super Precision being the chronometer-adjusted Bubbleback counterpart. Dial text reads “SUPER PRECISION.”


'''Refs 6422, 6426, 6694''' — mid-to-late Precision Oysters through the 1950s and 1960s, built on the Cal. 1200 manual-wind base that succeeds the 10½ Hunter family.
The thread that connects the 3003 of 1937 to the 6426 of the 1970s is the same editorial logic: manual-wind Oyster, adjusted movement, no chronometer certificate, "OYSTER PRECISION" on the dial. Rolex stopped manual-wind Precision production in the mid-1980s, by which point the automatic Oyster Perpetual and Datejust lines had absorbed the non-sport catalog.

Neither 3003 nor 3004 has a substantial auction record at the major houses. Phillips, Sotheby’s, Christie’s, Antiquorum, Bonhams, and Heritage have all passed Oyster Precisions of this era through their sale rooms, but the indexed record for the specific numbers 3003 and 3004 is thin — and where listings do surface, they tend to treat the references interchangeably with the broader late-1930s Precision population.

The explanation is partly documentary. Early Precision dial text identifies a watch as a Precision; early case numbering and caseback reference-stamping on Oysters of this era is inconsistent; dealers cataloguing a late-1930s “Rolex Oyster Precision” often list the watch without isolating whether the caseback reads 3003, 3004, or one of the near-neighbour references (3009, 3019, 3042, and similar small-batch Oysters of the period). Where the 3003 or 3004 number is confirmed, it is usually because the caseback interior has been photographed and transcribed.

'''Caseback reference'''. The only reliable identification of a 3003 or 3004 is the reference number stamped inside the caseback. A late-1930s Oyster Precision with no accessible caseback photograph should be treated as a generic Precision until the reference is confirmed.

'''Dial text'''. “ROLEX OYSTER PRECISION” on three lines is period-correct. A dial reading only “Rolex Oyster” without Precision is either earlier or a different reference; a dial reading “SUPER PRECISION” or “EXTRA PRECISION” is a higher-grade sibling in the same naming family, not the 3003/3004 entry-level designation.

'''Dial originality'''. As with any 1930s Rolex, refinished dials are the norm rather than the exception. An original dial with even patina, period-correct “OYSTER PRECISION” printing, and matching hand aging carries a substantial premium but requires specialist verification. The refinisher population active through the mid-twentieth century produced Precision dials that are difficult to distinguish from originals without side-by-side comparison to documented period examples.

The 3003 and 3004 are not collector-trophy references. They do not have the Bubbleback mystique of the 1858, the auction presence of the 4467, or the sport-icon lineage of the later Submariner. They are quiet references — small, conservative, manual-wind, dressy. The 1930s catalog is full of references like them, and most of the 3003/3004 population has been absorbed into generic “late-1930s vintage Rolex Oyster” dealer listings over the years.

'''Differentiation between 3003 and 3004'''. The Field Manual treats them as a pair. What distinguished them at the factory-catalog level — case material allocation, dial configuration, retailer channel — is not documented in surfaced sources. The two references may have served two subtly different points in the 1937 Precision lineup, or they may have been near-identical twins with minor production variance between them. Until primary-document evidence surfaces, the pair is best treated as a single launch.
 
'''Production span and end date'''. The 1937 launch is documented. Production end is not. Subsequent Precision references (2595, 4220, and others) take over the segment through the 1940s, but whether the 3003 and 3004 themselves ran through the late 1930s only, or continued in parallel with their successors, is not resolved in the indexed record.
 
'''Caliber transition'''. 10½ Hunter on early examples, Cal. 700 on later examples is the most parsimonious reading. The actual crossover point — and whether individual 3003 and 3004 watches saw both calibers across the run — is not documented.


'''Auction surface'''. The relative absence of 3003 and 3004 numbered lots at the major houses raises the question of whether the references simply had small production runs, whether surviving examples have been absorbed into generic Precision catalog entries without reference identification, or both. The indexed record is too thin to distinguish between these possibilities.
What makes them worth naming is the line they open. For forty-seven years, every Rolex that carried "PRECISION" on the dial was doing so as a direct continuation of the segment these two references established in 1937.

Rolex 3003 Oyster Precision (1937) — one of the first two Rolex references to carry the 'Precision' designation.
Rolex 3003 Oyster Precision (1937) — one of the first two Rolex references to carry the 'Precision' designation.

Precision -> 3003

The 3003 and 3004 are the first Rolex Precision references. They launched together in 1937 as a matched pair, and they open a line that runs, under one Precision designation after another, for the next forty-seven years. Every Rolex ever called a "Precision" Oyster traces back to these two references. The automatic Oyster Perpetual had arrived in 1933 on the Bubbleback platform; the 3003 and 3004 established the parallel track: manual-wind Oyster, no chronometer certificate, sold at a lower price point, aimed at the buyer who wanted a waterproof Rolex without the rotor.

The antique-era timeline in The Vintage Rolex Field Manual sets the launch down precisely: "Launch of the Rolex Precision (refs. 3003 & 3004) and Centergraph (ref. 3642)." Three references, one year, one entry. The Centergraph, a single-button Oyster chronograph, is the third child of 1937 and is addressed briefly below as a contemporary sister reference. The 3003 and 3004 are the focus here.

The differentiation between 3003 and 3004 at the parts-catalog level is not documented in surfaced sources. The Field Manual treats them as a pair. Dealer and auction listings for the specific numbers 3003 and 3004 are thin. Both references surface more frequently in the broader context of the early Precision population than as numbered lots in their own right.

What "Precision" meant

Rolex graded these early movements by regulation level rather than by radically different architecture. Prima, Extra Prima, and Ultra Prima indicate more about adjustment and finishing than about a different movement design.

By the mid-1930s the Prima names were giving way to Precision, Extra Precision, and Super Precision. The logic stayed the same: different regulation grades on broadly similar movement architecture, with Precision below full chronometer status.

This is the key distinction. The Precision line sits outside the Chronometer line. A Rolex buyer in 1937 choosing an Oyster Precision was choosing a waterproof, adjusted, manual-wind Oyster that did not carry the chronometer-certificate premium of the Oyster Perpetual Chronometer or the Oyster Chronometre. It was the same Oyster case, the same serious movement, and the same warranty against dust, water, and climate, minus the Neuchâtel or Kew certificate and the price that came with it.

The 3003 and 3004 are where that segment starts.

The movement

The period-correct movement for the 3003 and 3004 is a 10½-ligne Hunter-type Rolex caliber, the same family that powered the mid-1930s manual Oysters across the catalog. Fifteen jewels on base-grade examples, seventeen on better ones. Monometallic balance with the Rolex Patent Superbalance, Breguet overcoil, straight-line lever escapement, rhodium-plated, adjusted in six positions for all climates. The Superbalance and six-position adjustment text appears on the movement itself, the same specifications Rolex had been putting on its Hunter-type manual Oysters since the late 1920s.

Cal. 700, the purpose-designed thin manual-wind Precision caliber, arrives in 1938, a year after the 3003/3004 launch. Early 3003 and 3004 examples therefore sit just before the Cal. 700 transition, on the older 10½ Hunter base. Later production may carry Cal. 700 in the same cases; the transition is not cleanly documented in surfaced sources.

No shock protection. Incabloc and KIF arrive on Rolex calibers in the late 1940s with the A.296. The 3003 and 3004 movements predate that by more than a decade, and they should be treated as unprotected by modern standards.

The case

Standard Oyster construction for the era: three-piece, threaded bezel, mid-case, and caseback, with the screw-down Oyster crown on its patented left-hand-thread-replacement dog-clutch design. Diameter typically falls in the 33–34 mm range, small by modern standards and conventional for a 1937 men's Oyster. Lugs are soldered directly to the mid-case in the early-Oyster manner. Materials follow the usual mid-1930s Rolex range: stainless steel, 9ct yellow gold for the British market, higher-karat gold for other markets, rose gold examples in parallel.

Caseback signatures on Oysters of this period carry the familiar "Oyster Watch Co." and patent-reference engravings. The reference number itself sits on the caseback interior in most cases, not on the outside.

The bezel is smooth and polished. Engine-turned bezels on Precision-line watches arrive later, on the mid-1940s and 1950s Speedking-family references.

The dial

"ROLEX OYSTER PRECISION" is the dial text: three lines, centered under 12. Layout is conventional for a 1937 Oyster: Arabic numerals or applied baton indices, sub-seconds at 6, restrained printing, no calendar aperture. Two-tone sector dials appear in period photography, consistent with the Art Deco dress-watch conventions of the late 1930s. Radium-luminous numerals turn up occasionally but are less common on Precision-line Oysters than on the sporting Oyster Perpetuals and Oyster Army references that follow.

The dial text is the primary identifier. A late-1930s Oyster dial reading "ROLEX OYSTER PRECISION" is, by definition, a Precision-line watch, and in 1937 the only references carrying that text are the 3003 and the 3004. Earlier Oysters carry "Rolex Oyster" without the Precision designation; later Precision references use the same three-line layout into the 1960s.

The 1937 timeline entry — and the Centergraph

The antique-era timeline in The Vintage Rolex Field Manual treats 1937 as a three-reference year for Rolex. The 3003 and 3004 open the Precision line. Reference 3642, the Centergraph, launches in the same entry.

The Centergraph is a different animal: a single-button Oyster chronograph, center-seconds, with a 10½-ligne rhodium-plated movement, eighteen jewels, Superbalance, and a lever escapement. Production was tiny. Antiquorum's 1996 catalog entry for the 3642 described the reference as "produced in stainless steel only, in less than 50 examples." Names varied across the run. Zerograph and Centergraph were used interchangeably in period references, and the reference number also appears in some catalogs as 3462 (likely a transcription error for 3642).

The Centergraph does not share a platform with the 3003 and 3004. It is a chronograph; they are time-only Precisions. What they share is the 1937 launch year and the serious-movement specification (six-position adjustment, Superbalance, Breguet overcoil). In the Field Manual's timeline they are the same entry. In the market they are not comparable: Centergraphs, when they surface, are five-figure rarities; Precisions of the 3003/3004 era are modest vintage Oysters.

What came after

The Precision label does not stop with the 3003 and 3004. It continues through later small manual-wind Oysters, early automatics, and eventually the long Oyster Precision line of the second half of the century. The 3003 is simply one of the earliest clear starting points.

The thread that connects the 3003 of 1937 to the 6426 of the 1970s is the same editorial logic: manual-wind Oyster, adjusted movement, no chronometer certificate, "OYSTER PRECISION" on the dial. Rolex stopped manual-wind Precision production in the mid-1980s, by which point the automatic Oyster Perpetual and Datejust lines had absorbed the non-sport catalog.

Auction and dealer surface

Neither 3003 nor 3004 has a substantial auction record at the major houses. Phillips, Sotheby's, Christie's, Antiquorum, Bonhams, and Heritage have all passed Oyster Precisions of this era through their sale rooms, but the indexed record for the specific numbers 3003 and 3004 is thin. Where listings do surface, they tend to treat the references interchangeably with the broader late-1930s Precision population.

The explanation is partly documentary. Early Precision dial text identifies a watch as a Precision; early case numbering and caseback reference-stamping on Oysters of this era is inconsistent; dealers cataloguing a late-1930s "Rolex Oyster Precision" often list the watch without isolating whether the caseback reads 3003, 3004, or one of the near-neighbour references (3009, 3019, 3042, and similar small-batch Oysters of the period). Where the 3003 or 3004 number is confirmed, it is usually because the caseback interior has been photographed and transcribed.

In the dealer market the 3003 and 3004 trade as modest vintage Oysters. Low four figures for clean stainless steel examples, more for unrestored gold cases and period-correct dials. These are not five-figure watches outside unusual configurations, retailer co-signing, or exceptional provenance.

What to look for

The caseback reference is the only reliable identification of a 3003 or 3004. A late-1930s Oyster Precision with no accessible caseback photograph should be treated as a generic Precision until the reference is confirmed.

On the dial, "ROLEX OYSTER PRECISION" on three lines is period-correct. A dial reading only "Rolex Oyster" without Precision is either earlier or a different reference; a dial reading "SUPER PRECISION" or "EXTRA PRECISION" is a higher-grade sibling in the same naming family, not the 3003/3004 entry-level designation.

The period-correct movement is a 10½-ligne Hunter-type manual-wind with Superbalance text and six-position adjustment. A Cal. 700 in the same case is plausible for later production. Anything else (automatic movements, later manual calibers, or non-Rolex ébauches) indicates a service replacement or a reference mismatch.

The 3003 and 3004 use soldered fixed lugs in the early-Oyster manner. Spring-bar lugs on a claimed 3003 are a sign of heavy case modification or a misattribution.

On dial originality, as with any 1930s Rolex, refinished dials are the norm rather than the exception. An original dial with even patina, period-correct "OYSTER PRECISION" printing, and matching hand aging carries a substantial premium but requires specialist verification. The refinisher population active through the mid-twentieth century produced Precision dials that are difficult to distinguish from originals without side-by-side comparison to documented period examples.

Why it matters

The 3003 and 3004 are not collector-trophy references. They do not have the Bubbleback mystique of the 1858, the auction presence of the 4467, or the sport-icon lineage of the later Submariner. They are quiet references: small, conservative, manual-wind, dressy. The 1930s catalog is full of references like them, and most of the 3003/3004 population has been absorbed into generic "late-1930s vintage Rolex Oyster" dealer listings over the years.

What makes them worth naming is the line they open. For forty-seven years, every Rolex that carried "PRECISION" on the dial was doing so as a direct continuation of the segment these two references established in 1937. Prima became Precision; Ultra Prima became Super Precision; the logic stayed the same. The 3003 and 3004 are the point where the naming shifts, and the point where Rolex formally committed to a permanent non-chronometer manual-wind segment alongside the automatic Oyster Perpetual.
