Add reference-specific sourcing: seven verified Bonhams auction lots (1988-2005) - case/movement numbers, hammer prices, tropical-purple dial and 93258 bracelet corroboration; add missing Champagne Serti dial section, correct false 'no gem-set variant' claim
Deep correctness, grounding, image and anti-slop audit: qualify 16618 production, dial, bracelet, fitment, special-branch and market claims.

The 16618 is the full 18k yellow-gold Submariner Date of the cal. 3135 era. It ran alongside the two-tone 16613 for twenty years and changed the same way the 16613 did, in increments, without a single clean break in the run.
The 16618 is the full 18k yellow-gold Submariner Date of the caliber 3135 era. It ran alongside the two-tone 16613 and is generally dated from about 1988 until 2008 or 2009, depending on whether a source means factory production or final delivery stock. The reference changed in stages rather than at one clean cutoff.


It sits in the middle of the gold Submariner lineage that starts with the first gold Submariner in 1969 and continues to the present: 1680/8 (1969), then the [[Reference:16808|16808]], then the 16618, then the [[Reference:116618|116618]], then the 126618. That makes it the second-longest chapter in the line, and the one covering the gold Submariner at its most technically mature — Microstella regulation, solid end links, sapphire crystal — while still wearing the aluminum bezel insert that ties it to the pre-ceramic era.
It follows the 1680/8 and 16808 in the gold Submariner line and precedes the ceramic-bezel 116618. Its 40mm gold case, caliber 3135, sapphire Cyclops crystal, and aluminum bezel identify it as a pre-Cerachrom generation.

The gold Submariner is the longest continuous precious-metal thread in the family, and the 16618 is its long modern middle chapter. Three references share the cal. 3135 Submariner Date architecture: the steel 16610, the two-tone Rolesor 16613, and the full-gold 16618. Case dimensions, movement, and crystal are common to all three, and only the metal changes. The 16618 is the top of that range and by a wide margin the heaviest watch in it.
The 16618 is the full-gold member of the caliber 3135 Submariner Date group, alongside the steel 16610 and Rolesor 16613. They share the broad case and movement architecture, while the case, bezel, bracelet, and clasp materials differ. The gold construction makes the 16618 heavier than the steel and two-tone versions.


What changed inside the reference arrived in pieces. Lume ran through three generations, the bracelet gained solid end links, the rehaut picked up its engraving, and no single year marks the break. A 1989 16618 and a 2008 16618 are the same reference and noticeably different watches.

A late-1980s watch and a late-run watch carry the same reference number but can differ in lume, bracelet, rehaut, and other parts.

The 16618 tracks the 16613 change for change, in full gold. Dial lume moves from tritium through Luminova around 1998 to Super-Luminova in the late years. The bracelet moves from the 93158 with hollow end links to the 93258 with solid end links around 2000. The inner rehaut stays plain through the first two thirds of production and picks up the engraved ROLEX ROLEX text with the serial at the 6 o'clock position from around 2005.
Collector and auction references describe the same broad stages seen on the 16613: tritium, then non-tritium lume; a bracelet change from 93158 to 93258; and an engraved rehaut on later examples. Rolex has not published a complete serial-linked change chart, so the individual parts and service history remain decisive.

Early watches carry tritium lume (marked T SWISS T or T<25) on the 93158 bracelet with hollow end links. The plain rehaut and hollow-link bracelet date these examples firmly to the pre-millennium era. Early tritium examples are the most sought-after configuration in the twenty-year run. The earliest documented example at auction is a c.1988 sunburst-blue-dial 16618 (movement no. 5498018, case no. L930086) offered at Bonhams New York in October 2022, estimated at US$35,000–55,000; it did not sell.

=== Lapis lazuli dial ===


A lapis lazuli stone-dial variant of the 16618 is documented on Rolex Forum. A polished slab of lapis lazuli, a deep-blue semi-precious stone with characteristic gold pyrite flecking, replaces the standard painted dial. Rolex made these in-house, they are rare, and they carry substantial premiums. Authentication is exacting: genuine Rolex stone dials have specific finishing and marker-setting characteristics, and an aftermarket stone-dial trade grew up alongside them.

The stone and marker construction should be checked against provenance and specialist references; appearance alone does not establish factory origin, and aftermarket stone dials exist.

Rolex Forum documents 16618 dials co-signed "Tiffany & Co." below the coronet and fitted with sapphire and diamond hour markers. These date from the years when Tiffany & Co. was an authorized Rolex dealer and co-signed dials on select references. Surviving examples are rare and the dual-brand provenance drives significant premiums. The co-signature is the thing to authenticate: aftermarket Tiffany-stamped dials exist, and the gap between genuine and fake is wide enough to make faking worthwhile.
Collector and auction records document 16618 dials co-signed Tiffany & Co. with gem-set markers. A co-signature requires provenance and construction checks because aftermarket Tiffany-stamped dials exist; no premium or factory status should be inferred from the stamp alone.

The crystal is sapphire with Cyclops. The bezel insert is aluminum in blue or black, and it fades and scratches with use. That cuts both ways: it is a condition factor at market, and it is what makes an older gold Submariner look worn in instead of untouched. The ceramic insert only arrived with the 116618 that followed.
The crystal is sapphire with a Cyclops magnifier. The blue or black aluminum bezel insert can scratch, fade, and be replaced. Cerachrom arrived with the 116618 successor.


Early production carries what Rolex Forum collectors call a Flat 3 bezel — a vintage-style font on the insert in which the numeral 3 at the 15-minute position uses a flatter, more angular form. The Flat 3 is an early-production identification point, carried over from the outgoing 16808 generation. Later 16618 bezels moved to the more rounded numerals that became standard across the family.
Collector references describe an early ‘Flat 3’ insert font in some examples, with a flatter form at the 15-minute numeral. It can support a parts assessment, but replacement inserts and overlapping production make it an identification lead rather than a stand-alone date rule.

The early bracelet is a full 18k gold Oyster with Fliplock clasp, and it is prone to stretching over time.

Sources disagree on 93158 end-link construction. Some describe hollow end links throughout, others solid end links from the start, and nothing published settles it. An end-link claim on any given example is worth checking against the hardware rather than against the bracelet reference number.

=== Later bracelet: 93258 (solid end links, SEL) ===


The 93258 brought solid end links — SEL, in collector shorthand — to the full-gold Submariner bracelet. Solid end links close the gap between bracelet and case more tightly than hollow construction, and they remove the flex that hollow-link bracelets tend to develop with age. The transition landed around 2000, mirroring the pattern of the steel and two-tone references. Rolex had first used solid end links on the Sea-Dweller before spreading them across the Submariner family.
The 93258 is associated with solid end links, called SEL in collector shorthand. The change is generally placed around 2000, but no complete factory cutoff is published. Bracelet construction and stretch should be checked directly.


The 93158-to-93258 transition is a key authenticity checkpoint. A post-2000 serial 16618 should be on a 93258. A 93158 on a late-serial watch usually points to a bracelet swap or a mismatched example. A circa-2005 blue-dial lot sold by Bonhams in February 2020 (hammer GBP 18,000 against a GBP 8,000–12,000 estimate) was fitted with a 93258 Oyster bracelet and a clasp stamped OP2, corroborating the 93258 fitment on that later production.
The 93158-to-93258 change can help assess fitment, but it is not a stand-alone authenticity rule. A later watch with an earlier bracelet may reflect a replacement, retained original, or incomplete provenance. A circa-2005 blue-dial lot sold by Bonhams in February 2020 (hammer GBP 18,000 against a GBP 8,000–12,000 estimate) was fitted with a 93258 Oyster bracelet and a clasp stamped OP2, corroborating the 93258 fitment on that later production.


Clasp date codes follow the standard Rolex scheme of the period. An S stamp indicates a service replacement. The code dates the bracelet alone; the watch head's own age is a separate question.

No military or institutional special branches are documented for the 16618. Beyond the lapis lazuli and the Tiffany-signed dials, the champagne "Sultan" diamond-and-sapphire dial catalogued by Bonhams (see Dial map, above) is the clearest documented factory gem-set configuration.

Rolex Forum documentation places the no-holes case on the 16618 at around the D serial (roughly 2005–2006), following the same timing as the steel 16610 and two-tone 16613. Earlier examples have drilled lug holes; D-serial and later examples do not. The change is a consistent dating and authenticity checkpoint across the 3135-era Submariner generation.

The 16618 appears at auction less often than the two-tone 16613 and more often than the shorter-run 16808. Full-gold construction puts it at the top of the 3135-era Submariner range by weight and by material value.
Auction records document both blue and black configurations, along with gem-set and early examples. The dated lots below are individual observations; condition, originality, papers, bracelet components, provenance, venue, and date all affect the result. No current reference-wide price band is asserted here.
 
Blue LB is the more commonly traded configuration; black LN trades at a discount. Within both dials, the early tritium examples on hollow-link bracelets draw the most attention from collectors who prize the historical specificity of the opening years.
 
Bonhams has catalogued the reference repeatedly across its London, New York, Paris and online sales. A blue-dial example with a documented 1997 sale sold for US$9,000 at a Bonhams auction in August 2010; by 2020–2025 hammer prices for standard blue and black configurations had moved into the GBP 16,000–20,000 and US$22,000 range, with the gem-set "Sultan" dial hammering at GBP 20,000 in 2023. The single c.1988 example found in the auction record — the earliest documented 16618 to come to market — carried a US$35,000–55,000 estimate in 2022 and went unsold, a reminder that early tritium examples do not automatically clear reserve even when they anchor the production timeline.

The current-generation 126618LB retails at $48,600 USD at Rolex authorized dealers, with a 41mm case, caliber 3235, and ceramic bezel. The aluminum-insert 16618 trades at a significant discount to that, reflecting the older movement, the aluminum bezel, and the smaller case. The modern retail figure is what frames the category the 16618 sits directly beneath.
The 126618 successor uses a 41mm case, caliber 3235, and Cerachrom bezel. Current retail and secondary prices change over time, so no comparison or discount is stated here.

Rolex Submariner 16618 in 18k yellow gold with blue dial, full watch and bracelet
Rolex Submariner 16618 in 18k yellow gold with blue dial, full watch and bracelet

The 16618 is the full 18k yellow-gold Submariner Date of the caliber 3135 era. It ran alongside the two-tone 16613 and is generally dated from about 1988 until 2008 or 2009, depending on whether a source means factory production or final delivery stock. The reference changed in stages rather than at one clean cutoff.

It follows the 1680/8 and 16808 in the gold Submariner line and precedes the ceramic-bezel 116618. Its 40mm gold case, caliber 3135, sapphire Cyclops crystal, and aluminum bezel identify it as a pre-Cerachrom generation.

Where it sits in the gold Submariner lineage

The 16618 is the full-gold member of the caliber 3135 Submariner Date group, alongside the steel 16610 and Rolesor 16613. They share the broad case and movement architecture, while the case, bezel, bracelet, and clasp materials differ. The gold construction makes the 16618 heavier than the steel and two-tone versions.

What changed inside the reference arrived in pieces. Lume ran through three generations, the bracelet gained solid end links, the rehaut picked up its engraving, and no single year marks the break. A late-1980s watch and a late-run watch carry the same reference number but can differ in lume, bracelet, rehaut, and other parts.

Production outline

Collector and auction references describe the same broad stages seen on the 16613: tritium, then non-tritium lume; a bracelet change from 93158 to 93258; and an engraved rehaut on later examples. Rolex has not published a complete serial-linked change chart, so the individual parts and service history remain decisive.

Early production (~1988–1998)

Early watches carry tritium lume (marked T SWISS T or T<25) on the 93158 bracelet with hollow end links. The plain rehaut and hollow-link bracelet date these examples firmly to the pre-millennium era. Early tritium examples are documented in auction catalogues. Bonhams offered a circa-1988 blue-dial example in October 2022 with a US$35,000–55,000 estimate; it did not sell. That lot is evidence for one watch, not a general market ranking.

Mid production (~1998–2005)

Dial lume moved from tritium to Luminova and then to Super-Luminova. The bracelet moved to the 93258 with solid end links around 2000. Published sources do not pin either changeover to a single serial band. A blue-dial example purchased new on 18 March 2003 sold at Bonhams in June 2025 for a hammer price of US$22,000 against a US$12,000–18,000 estimate, cased at no. P616061.

Late production (~2005–2009)

The late watches carry the engraved inner rehaut, with ROLEX ROLEX repeating around the ring and the serial at 6 o'clock. Late examples share some visible features with the following 116618, but parts and service history still require individual inspection.

Movement notes

Caliber 3135 runs throughout, the same movement used in the steel 16610 and the two-tone 16613. Quick-set date, 28,800 vph, Microstella regulation for fine-tuning. The 3135 is widely documented across Rolex references. Service interval, condition, and performance depend on the individual movement and its maintenance history.

Case material has no bearing on movement specification. A 16618 and a 16610 from the same year are mechanically identical; only the metal around the movement differs.

A factory gem-set configuration documented at auction: Bonhams catalogued one under its own "Sultan" dial name in June 2023, a sunburst champagne dial with diamond-set hour markers and baguette-sapphire-set quarters, paired with a gold bezel and blue calibrated insert. The lot came from the original owner, who bought it new on 28 December 1998, with box, punched guarantee and a 1998–1999 calendar card, and sold for a hammer price of GBP 20,000 against a GBP 20,000–30,000 estimate.

Rolex Submariner 16618 — 18k yellow gold with blue dial and bezel

Blue sunburst dial with gold applied markers and gold hands. This is the more commonly photographed and traded configuration of the two. Lume runs from tritium through Luminova to Super-Luminova across the run, on the same schedule as the 16613.

Rolex Forum collectors have documented tropical purple shift on blue 16618 dials. After decades of UV exposure and chemical aging the pigment oxidizes to a purple or plum hue, with forum examples drawn from 1989 and 1991 production. An even, attractive shift is treated as a desirable feature rather than a defect. The tropical shift is better documented on the 16613 because production volumes were higher, but it occurs identically on the 16618. A major auction house has now catalogued the shift directly rather than as a forum observation alone: Bonhams Cornette de Saint Cyr listed a circa-1991 example in October 2025 with the dial described in its own catalogue text as "sunburst blue/purple," selling for a hammer price of EUR 20,000 against a EUR 15,000–20,000 estimate.

Black dial (LN)

Black dial with gold applied markers. It surfaces less often in the secondary market and trades at a discount to the blue. A circa-1991 example sold at Bonhams in February 2024 for a hammer price of GBP 16,000 against a GBP 8,000–12,000 estimate; its clasp was stamped S7, a service-replacement code rather than a period-original stamp.

Lapis lazuli dial

A lapis lazuli stone-dial variant of the 16618 is documented on Rolex Forum. Some 16618 examples are documented with lapis lazuli stone dials. The stone and marker construction should be checked against provenance and specialist references; appearance alone does not establish factory origin, and aftermarket stone dials exist.

Tiffany & Co. co-signed dials

Collector and auction records document 16618 dials co-signed Tiffany & Co. with gem-set markers. A co-signature requires provenance and construction checks because aftermarket Tiffany-stamped dials exist; no premium or factory status should be inferred from the stamp alone.

Case, bezel, crystal, and crown

The entire case is 18k yellow gold: body, bezel, crown, crown tube, and case back, with crown guards present and a Triplock crown sealing to 300m. It wears substantially heavier than the steel 16610 of the same generation.

The crystal is sapphire with a Cyclops magnifier. The blue or black aluminum bezel insert can scratch, fade, and be replaced. Cerachrom arrived with the 116618 successor.

Collector references describe an early ‘Flat 3’ insert font in some examples, with a flatter form at the 15-minute numeral. It can support a parts assessment, but replacement inserts and overlapping production make it an identification lead rather than a stand-alone date rule.

The inner rehaut is plain on early and mid-production watches. Late examples carry the engraved ROLEX ROLEX text.

Hallmarks follow the standard Rolex precious-metal marking of the period. Helvetia bust with "G" Geneva assay mark through the mid-1990s, then the St. Bernard dog Barry mark from 1995 onward.

Along with lume type, the bracelet is one of the primary authenticity and dating checkpoints on a 16618, running on the same transition schedule as the two-tone 16613.

Early bracelet: 93158

The early bracelet is a full 18k gold Oyster with Fliplock clasp, and it is prone to stretching over time. Gold is softer than steel, and daily wear on a heavy gold case will eventually open play between the links. Stretch is common on well-worn examples and a known condition factor at market. The 93158 is associated with early production. Sources disagree about end-link construction within the reference, so the hardware should be checked on the individual bracelet rather than inferred from the bracelet number alone.

Later bracelet: 93258 (solid end links, SEL)

The 93258 is associated with solid end links, called SEL in collector shorthand. The change is generally placed around 2000, but no complete factory cutoff is published. Bracelet construction and stretch should be checked directly.

The 93158-to-93258 change can help assess fitment, but it is not a stand-alone authenticity rule. A later watch with an earlier bracelet may reflect a replacement, retained original, or incomplete provenance. A circa-2005 blue-dial lot sold by Bonhams in February 2020 (hammer GBP 18,000 against a GBP 8,000–12,000 estimate) was fitted with a 93258 Oyster bracelet and a clasp stamped OP2, corroborating the 93258 fitment on that later production.

Clasp date codes follow the standard Rolex scheme of the period. An S stamp indicates a service replacement. The code dates the bracelet alone; the watch head's own age is a separate question.

Special branches

The page's documented branches are gem-set or special dials, including the champagne configuration catalogued by Bonhams. No military or institutional branch is asserted here without a named catalogue record.

No-holes case (D-serial onward)

Rolex Forum documentation places the no-holes case on the 16618 at around the D serial (roughly 2005–2006), following the same timing as the steel 16610 and two-tone 16613. Earlier examples have drilled lug holes; D-serial and later examples do not. The change is a useful lead when combined with serial, movement, bracelet, and service evidence; it is not a stand-alone authenticity test.

Historical market and auction record

Auction records document both blue and black configurations, along with gem-set and early examples. The dated lots below are individual observations; condition, originality, papers, bracelet components, provenance, venue, and date all affect the result. No current reference-wide price band is asserted here.

Modern pricing benchmark

The 126618 successor uses a 41mm case, caliber 3235, and Cerachrom bezel. Current retail and secondary prices change over time, so no comparison or discount is stated here.
