Rolex 3134 Bubbleback


Bubbleback3134

The 3134 is a 32 mm tonneau Oyster Perpetual from the 1940s and 1950s, fitted with a 9¾-ligne Rolex automatic. Catalogued watches have either subsidiary or centre seconds. Most documented cases are stainless steel; one combines steel with yellow gold. Two documented examples have California dials, though neither source establishes that its dial is original to the watch.

Where it sits in the line

The 3134 belongs to the two-digit-suffixed Oyster Perpetual references 3130 through 3135. The group includes different seconds layouts and case metals. Antiquorum's 1992 and 2013 examples have subsidiary seconds. Exclusive Timepieces lot 227 and the Luxe Auctioneers example have centre seconds; the cited dealer listing does not establish the seconds layout of its c.1941 California-dial watch.

The documented 3134 cases are predominantly steel. The four auction lots comprise three steel watches and one steel-and-yellow-gold watch; a separate dealer-listed example is also steel. No solid-gold 3134 appears in the cited records.

Production outline

Auction catalogues date documented 3134 examples to the 1940s, c.1945, the 1950s and 1957. A dealer dates another example to c.1941. No source states a production start or end for the reference.

These dates are catalogue estimates, not a production window. Exclusive Timepieces dates case 168751 to 1957, while Hodinkee places the end of Bubbleback production in the mid-1950s. The sources do not resolve that difference.

Movement notes

Antiquorum Geneva's 1992 lot 181 describes a self-winding 9¾-ligne movement with 17 jewels, lever escapement, monometallic balance and a self-compensating Breguet balance spring. Exclusive Timepieces lot 227 also gives a 9¾-ligne automatic. Antiquorum's 2013 lot 143 records rhodium plating, a straight-line lever escapement and a Superbalance, but does not state the winding type or jewel count.

No documented lot names a caliber number. The subsidiary-seconds watches are consistent with Cal. 620 or the shock-protected Cal. 635; centre-seconds watches are consistent with Cal. 630 or 645. None of those fitments is confirmed by a movement photograph or catalogue description, so the caliber remains unresolved.

Dial map

 
Matte silver dial, applied luminous Arabic numerals and subsidiary seconds, case 104396
 
California dial in pink, half Roman and half Arabic, circa 1941
 
The second California example, marked Chronometer and running centre sweep seconds, circa 1945

The five documented examples fall into four dial configurations.

The matte silver dial with applied luminous Arabic numerals and subsidiary seconds appears on Antiquorum's 2013 example, case 104396. Case 168751 has a pink dial with luminous Arabic and squared numerals, an outer minutes track and centre seconds. A black subsidiary-seconds dial appears on the 1992 steel-and-yellow-gold example.

Two documented 3134s have half-Roman, half-Arabic California dials. Luxe Auctioneers dates one to c.1945, and a dealer dates the other to c.1941. Neither source establishes that the dial is original. Hodinkee notes that refinished California dials are common on Bubblebacks. Rolex filed Swiss patent CH221643 for the layout in May 1941; it was issued in June 1942.

Case, bezel, crystal, and crown

 
Case profile: curved lugs, inclined bezel, screw-down crown and the domed back the family is named for
 
Screw-down caseback with milled edge

Documented cases measure 32 mm across. Antiquorum's 2013 lot 143 is 14 mm thick; no second source gives thickness. The tonneau case has an inclined smooth bezel, acrylic crystal and screw-down crown.

Antiquorum's 2013 lot 143 calls the case "three body," and Exclusive Timepieces describes case 168751 as "composed of three parts." Both catalogue descriptions identify a three-part case.

Antiquorum's 1992 catalogue describes its steel-and-yellow-gold example as having "hooded fluted lugs," while case 168751 has curved lugs. No photograph of the 1992 watch has been located, so the hooded-lug description remains catalogue evidence rather than a visually confirmed sub-variant.

The side-profile photograph shows a domed caseback, although no auction description uses that term. Antiquorum's 1992 lot and Exclusive Timepieces lot 227 describe automatic movements. Exclusive Timepieces and Luxe Auctioneers catalogue the reference as a Bubbleback.

Bracelets, end links, and clasps

Only one documented example carries a bracelet: case 168751, fitted with a riveted steel Oyster. The bracelet is period-correct for a 1940s steel Bubbleback, but no documentation ties it to original delivery. The Luxe example has an associated leather strap and a Rolex steel tang buckle; the catalogue does not claim either as original delivery.

Case-metal suffixes

Rolex used slash suffixes on Bubbleback references to distinguish case metals. Colin A. White's The Vintage Rolex Field Manual documents the system and gives 1578/7 and 1578/8 as examples.

No cited source confirms a complete suffix-to-metal map for reference 3134. The documented cases are steel and steel with yellow gold; the cited records contain no solid-gold example.

Case 168751 sold for EUR 13,650 against a EUR 6,000–12,000 estimate. Luxe Auctioneers reported a USD 3,250 hammer for its California-dial example; EveryWatch reports USD 4,063 including fees. The Luxe catalogue notes dial toning and minor spotting and describes the leather strap as associated.

Both indexed Antiquorum lots were unsold. Four published results across thirty-four years do not establish a market level for the reference.
