Reference:16613LB

Submariner -> 16613LB

The 16613LB is the blue-dial, blue-bezel two-tone Submariner Date of the caliber 3135 era, in production from 1989 to 2009. Collectors call it the Bluesy, the nickname applied to every blue-on-blue two-tone Submariner Rolex has produced from the 16803 through to the current 126613LB, but the 16613LB is the version most buyers picture when the word lands. Twenty years on a single reference number is long for any sport Rolex, and the LB absorbed every Submariner detail upgrade of the period — tritium giving way to Luminova and then Super-Luminova, hollow end links giving way to solid, and a plain inner rehaut giving way to the engraved ROLEX ROLEX band — before the Cerachrom 116613LB replaced it.

LB denotes lunette bleue (blue bezel) in Rolex's standard suffix system. The 16613LB should not be confused with the 116619LB Smurf, which is the blue-on-blue Submariner cased in solid 18k white gold rather than two-tone Rolesor — a different reference, a different metal, and a different price tier. The 16613LB is the steel-and-yellow-gold blue Sub.

Where it sits in the line

The 16613LB is the blue configuration of the Rolesor member of the 3135-era Submariner Date trio. Rolesor is Rolex's term for steel-and-gold construction, with gold in every visible wear surface. The steel 16610 carried the widest market and ran 23 years; the 16613 carried the two-tone configuration with an 18k yellow-gold bezel, gold center links, and a gold crown and crown tube on a steel case; the full-gold 16618 was the maximum-material version of the same architecture. All three share the 40mm case and the caliber 3135.

Within the 16613 pair the LB is the louder sibling. The blue-on-yellow-gold combination photographs as a statement piece, and the secondary market has consistently put the LB at a premium over the black 16613LN. The premium has held remarkably steady across the production run and into the post-discontinuation aftermarket — roughly the same logic that has separated the blue and black two-tone Subs through every generation since the 16803.

The 16613LB replaced the shorter-lived 16803, which had run from roughly 1984 to 1988 on the earlier caliber 3035. The substantive change at the generational boundary was the movement itself: the 3135 brought Microstella regulation and the higher frequency Rolex would carry forward for the next three decades. The Cerachrom 116613LB succeeded it in 2009, bringing the ceramic blue bezel insert, Maxi case, and Glidelock-equipped 97203 bracelet that defined the next chapter of the line.

Twenty years: what the production length means

A twenty-year run under one reference number is long for a sport Rolex, and in practice it means the 16613LB spans two distinct eras in the same catalog entry. Early production, 1989 to roughly 1998, carries tritium lume, the 93153 bracelet with hollow end links, a plain rehaut, and matte-finish components. Late production, roughly 2005 to 2009, carries Super-Luminova, the 93253 bracelet with solid end links, the engraved rehaut, and an overall finish much closer in character to the Cerachrom 116613LB that followed.

Early and late 16613LB examples do not look the same on the wrist. A tritium 16613LB on a hollow-link 93153 reads as a transitional late-vintage piece. A late Super-Luminova example with engraved rehaut reads as a modern pre-ceramic Submariner. Buyers who treat the reference number as a single object often conflate the two, and the price spreads within the reference reflect that.

Production outline

Early production (~1989–1998)

Early watches have tritium lume (marked T SWISS T or T<25 at six o'clock), the 93153 bracelet with hollow end links and Fliplock clasp, and a plain inner rehaut. These are the tritium-era 16613LB examples, and they sit visually closest to the outgoing 16803 generation.

Mid production (~1998–2005)

The dial lume transitioned from tritium to Luminova around 1998 and then to Super-Luminova within a year or two. The bracelet transitioned from 93153 to 93253 with solid end links around 2000. Exact changeover dates are not pinned to specific serial bands in the documented evidence.

Late production (~2005–2009)

Late watches gained an engraved inner rehaut, with repeating ROLEX ROLEX text and the serial number at the 6 o'clock position. The feature appeared somewhere between 2005 and 2008 depending on source. Late 16613LB examples sit closer in finish and detail to the 116613LB than to the early tritium watches that opened the run.

Movement notes

Caliber 3135 throughout the run. Quick-set date, 28,800 vph, Microstella regulation, roughly 48 hours of power reserve, COSC chronometer certification. Rolex used the same movement in the steel 16610, the full-gold 16618, the Datejust, and many other references from the late 1980s onward. The 3135 is one of the most reliable and best-documented calibers in the modern catalog, and no movement change happened during the 16613LB's run.

Later 3135 specimens received the Parachrom blue hairspring, a paramagnetic alloy more resistant to magnetic fields and temperature swing than the earlier hairspring. The exact transition point for Parachrom on the 16613LB is not firmly pinned in the documented evidence.

Dial map

The 16613LB dial is blue with a radial sunburst finish, applied gold hour markers, and gold Mercedes hands. Across the run the blue shifts across a wider range than the black LN dial: deep navy in low light, bright cornflower in direct sun, and a paler blue in the mid-tones that photographs rarely capture. Later-production dials show a more pronounced sunburst with sharper radial brushing than the flatter blue of early examples.

The key sub-variants:

Standard sunburst blue — the canonical 16613LB dial. Blue radial sunburst, applied gold markers, gold Mercedes hands. Tritium lume on early watches, Luminova then Super-Luminova on later examples. Tropical purple — blue 16613LB dials that have oxidized over decades to a distinctly purple or plum hue. The shift is driven by long UV exposure and slow chemical aging of the blue pigment, and it is progressive and irreversible. Tropical purple dials appear either evenly across the full face or in uneven patches depending on how the watch was worn and stored. The collector market treats an even, attractive tropical purple as a desirable feature rather than a defect, consistent with the broader market for tropical vintage Rolex dials. Factory Serti — silver-base gem-set dial, diamond hour markers, sapphire indices in the cardinal positions. The name comes from the French sertissage (gem-setting). Factory Sertis are not aftermarket conversions; Rolex produced them at the factory, and a clean factory Serti carries a substantial premium over an aftermarket gem-set dial that looks similar at a glance. The blue-bezel LB Serti is the more commonly encountered configuration of the gem-set 16613. Sultan dial (factory champagne Serti) — champagne base with diamond hour markers and sapphire accents, typically two baguette sapphires plus a triangular sapphire at twelve. The naming follows the collector convention used by the wider specialist trade — silver-base gem-set is "Serti", champagne-base gem-set is "Sultan". The name is not a reference to the Sultanate of Oman or the Khanjar emblem, which is a separate provenance line covered in Special branches below. Sultan dials are scarcer than silver Sertis and command premiums when papers and serial fall inside a coherent run.

The lume-text branches mirror the wider Submariner family. Early dials read T SWISS T or T<25 (tritium); a brief transitional window carries SWISS only (Luminova); late dials read SWISS MADE (Luminova then Super-Luminova). Dial text is the fastest way to date a 16613LB: T SWISS T = pre-1998, SWISS only = 1998–2000 transition, SWISS MADE = 2000 onwards.

Case, bezel, crystal, and crown

The case is 40mm 904L stainless steel with 18k yellow gold crown guards and a gold Triplock screw-down crown, rated to 300m. The crystal is sapphire with a Cyclops magnifier over the date window at three o'clock. The bezel is 18k yellow gold carrying a unidirectional 60-click graduated blue aluminum insert with a luminous pearl at twelve.

The blue aluminum insert is the 16613LB's most distinctive — and most variable — feature. Aluminum inserts scratch and fade with use, and the blue insert ages along its own pathway: heavy-wear examples lose colour to a paler, slightly grey-green blue at the high points, with the deeper navy holding longer in the recessed numerals. The faded look is widely considered desirable on a 16613LB; replacement inserts are widely available, and crisp original-finish blue inserts are increasingly hard to source. A check on bezel originality is part of any thorough authentication pass.

The inner rehaut is plain on early and mid-production watches. Late examples, from around 2005, carry the engraved ROLEX ROLEX band that became the signature of the late aluminum-bezel and Cerachrom Submariner.

Hallmarks on the gold components follow Rolex's standard precious-metal marking of the period. Earlier watches carry the Helvetia bust with G Geneva assay mark on the mid-case and bracelet components. After 1995, the St. Bernard dog Barry mark replaced the older Helvetia system.

Bracelets, end links, and clasps

Two-tone Oyster bracelet with steel outer links and 18k gold center links — The 16613 two-tone Oyster bracelet — steel outer links and 18k gold center links, shared by both the LB and the LN

Along with lume type, the bracelet is one of the two primary authenticity checkpoints on a 16613LB. Reading it correctly is how a buyer places a given watch within the 20-year production run.

Early bracelet: 93153 (hollow end links)

The 93153 is a two-tone Oyster bracelet with steel outer links and 18k gold center links, fitted with hollow end links and a Fliplock diver's-extension clasp. It covers early production through about 2000. A 16613LB on a 93153 with a tritium dial sits firmly in the pre-millennium collector tier.

Gold-through clasp transition

During the A-serial range (roughly 1999 to winter 2000), Rolex introduced the gold-through clasp, in which the gold extends through the full clasp body rather than sitting only on the exterior surfaces. Early A-serial 16613LB examples lack the gold-through clasp; late A-serial examples have it; all P-serial and later watches are expected to carry it. The detail is a useful dating check on examples that sit near the transition.

Later bracelet: 93253 (solid end links — SEL)

The 93253 brought solid end links — SEL, in collector shorthand — to the two-tone Submariner. Solid end links close the gap between bracelet and case more tightly than the older hollow type and give the watch a more substantial feel on the wrist. The transition landed around 2000, parallel to the SEL rollout on the steel 16610 and the gold 16618. Rolex had introduced solid end links on the Sea-Dweller first, then spread them across the Submariner family.

The 93153-to-93253 transition is a key authenticity checkpoint on the LB. A late-production 16613LB on a post-2000 serial should be on a 93253; a 93153 on a late-serial watch usually points to a bracelet swap or a mismatched example.

Clasp date codes follow the standard Rolex scheme of the period: 1976 = A through 1988 = M, 1989 = N, through 2000 = AB, 2001 = DE, up to 2010 = RS. An S stamp indicates a service replacement clasp. The code dates the bracelet, not the watch head.

Special branches

Factory Serti and Sultan

The factory Serti gem-set dial (silver base, diamond hour markers, sapphire indices) is the established gem-set configuration on the 16613LB. The Sultan dial is the rarer factory sibling, with the same gem-set architecture on a champagne base. Both are factory-original, and both carry premiums contingent on clean provenance and unambiguous factory origin. See the Dial map above for fuller treatment.

Khanjar caseback

A Khanjar 16613 — the curved dagger emblem of the Sultanate of Oman — is documented as a caseback engraving rather than as a dial signature. By the late 1990s the Omani commissions had moved off the dial and onto the caseback, fulfilled through Khimji Ramdas, the Omani retailer. Bukowskis lot 1023 (c.1998, serial U365470, Khanjar caseback engraving, Khimji Ramdas warranty card, Khanjar-stamped outer box; 140,000 SEK against 130,000–180,000 estimate) anchors the caseback-Khanjar 16613 in the late-1990s. ItalianWatchSpotter places the dial-to-caseback shift at the start of the 2000s. Khanjar dial 16613 examples are not documented; treat any claimed example as misidentified.

Panama Canal limited edition

A Panama Canal limited edition (75 pieces, c.1999) was retailed by Mercurio Joyero in Panama to commemorate the December 1999 transfer of canal sovereignty. Black dial with a gilt Panama Canal emblem at six o'clock and "Panama Canal — Canal de Panamá" inscription. Sotheby's Watches Online March 2020 lot 4 (c.1999, A946579, numbered 57/75, estimate CHF 25,000–40,000) is the strongest documented example. The Panama Canal commemoratives were issued on black-dial watches; the LB sub-line did not receive a parallel commission in the documented evidence.

Service-replacement dial caution

Rolex servicing routinely fitted Luminova dials to tritium-era watches once tritium dials were no longer manufactured. A pre-A-serial (pre-~1999) 16613LB with a SWISS MADE dial has almost certainly had a service replacement. The dial is not wrong — Rolex fitted it — but it is not the original configuration, and collectors treat the swap as a meaningful deduction.

Historical market and auction record

The 16613LB is the more recognisable of the two 16613 configurations, and it carries the premium that recognition implies. The Bluesy commands a steady price advantage over the 16613LN that has held across the production run and into the secondary market. Within the LB, the market sorts the run into early tritium watches on hollow-link 93153 bracelets, mid-run Luminova examples, late Super-Luminova examples with engraved rehaut and solid-link 93253 bracelets, factory Serti gem-set dials at the top tier, the rarer Sultan dial as a premium category, tropical purple dials as a discrete sub-market, and first-year nipple-dial examples as a dedicated specialist segment.

The successor 116613LB brought the Cerachrom ceramic bezel and the Maxi case at retail, and current Rolex pricing on the modern Bluesy has pulled the late aluminum-insert 16613LB up by a sympathetic amount. Early tritium watches and the special-dial variants follow their own premium logic that does not track the retail reference.
