The 16718 is the all-gold member of the 16710 generation, the 18K case-and-bracelet sister to the steel [[Reference:16710|16710]] and the two-tone [[Reference:16713|16713]]. Production is generally dated from 1989 to about 2005, when the 116718LN replaced it with a Cerachrom bezel. Caliber 3185, the 40mm Oyster case, and the independently adjustable local-hour GMT mechanism match the period 16710 architecture. Catalogues document black, brown sunburst, white, and gem-set dials.
The 16718 is the all-yellow-gold branch of the 16710 generation, alongside the steel [[Reference:16710|16710]] and two-tone [[Reference:16713|16713]]. Sources date the five-digit gold reference to the late 1980s or early 1990s and place its replacement by the 116718LN in 2005. It uses caliber 3185 for most of the run, a 40mm Oyster case, and the independent-hour GMT mechanism. Documented dials include black, brown, white, and gem-set configurations.

Within the five-digit GMT-Master II line the 16718 runs in parallel with the all-steel [[Reference:16710|16710]] and the two-tone [[Reference:16713|16713]] Rootbeer, and from 2005 with the ceramic 116718LN that replaced it. What it replaced in turn was the [[Reference:16758|16758]], built from 1979/80 to 1988 on caliber 3075, whose local hour moved only with the 24-hour hand in the synchronized manner of the original GMT-Master line.

The gold case-and-bracelet positioning carries over from the 16758. The independently adjustable local-hour mechanism and sapphire-crystal Oyster case with crown guards distinguish the 16718 generation. The next-generation gold GMT is the 116718LN, from 2005, running caliber 3186 under a Cerachrom ceramic bezel with a Maxi dial, Super Case, and solid-centre-link Oyster bracelet.

Production began in 1989. The 16718 entered the catalog as the gold partner to the new flyer-GMT 16710, retiring the 16758 it succeeded. The end year reads 2005 across editorial coverage and major-house lots, lining up with the Baselworld launch of the 116718LN as the 50th-anniversary green-dial replacement. A "2003" end date sometimes circulates; it traces to the steel 116710LN launch year, since the all-gold 116718LN is a 2005 release.
Production began in 1989. The 16718 entered the catalog as the gold partner to the new flyer-GMT 16710, retiring the 16758 it succeeded. The available editorial and auction material places the end of the five-digit all-gold reference around 2005, when the 116718LN was introduced with a Cerachrom bezel and green anniversary dial. A 2003 date appears in some listings but is not used here as a production endpoint.


Collector and auction references place a no-holes case and laser-etched coronet on later examples, often around 2002–2003. The exact transition and case-stamp notation require inspection of the individual watch.
A case-stamp transition runs c.2002–2003 alongside the steel and two-tone sisters, when the lug holes drop and the laser-etched coronet appears on the sapphire crystal at 6 o'clock. The 16718 follows the same case-revision sequence as the 16710 and 16713, although the gold case stamp is sometimes catalogued without the "T" suffix the steel sister carried.

Caliber 3185 powers most of the run, carrying over unchanged from the 16710 and 16713. It is a 31-jewel COSC chronometer beating at 28,800 vph with a 50-hour reserve, hacking seconds and a quickset date, a Glucydur balance regulated by four Microstella screws, and Kif Elastor shock protection. Its documented 3185 configuration uses a Nivarox hairspring with Breguet overcoil. The 16718 record does not establish a factory 3186 transition. The flyer mechanic with its independently adjustable local hour is the architectural break from the linked-hand 3075 that ran in the 16758.
Caliber 3185 powers most of the run, carrying over unchanged from the 16710 and 16713. It is a 31-jewel COSC chronometer beating at 28,800 vph with about a 50-hour reserve, hacking seconds, and a date that advances through the independently adjustable local-hour hand, a Glucydur balance regulated by four Microstella screws, and Kif Elastor shock protection. Its hairspring is flat Nivarox with a Breguet overcoil; the blue Parachrom arrives later, on caliber 3186. The independent local-hour hand is the main functional change from the linked-hand 3075 used in the 16758.


Published reference tables and auction records identify caliber 3185 for the 16718. A 3186 found in a 16718 case should be treated as an individual movement or service question and checked against the movement and serial documentation.
Late-production examples may carry the upgraded caliber 3186 with its Parachrom blue hairspring and the spring-loaded date mechanism that cured the 3185's GMT-hand creep. Where that changeover falls on the 16718 specifically is documented inconsistently, and the bulk of documented examples read cal 3185 throughout the run. A 3186 in a 16718 case is worth checking against the serial before money changes hands.

Black is a documented sport configuration. Early examples can have raised or nipple-style markers with tritium plots; later examples use applied markers with gold surrounds. The black insert is one documented pairing. Claims about relative dial stability or aging depend on the individual dial.
Black is the standard sport configuration: glossy black lacquer carrying nipple markers in earlier production and applied indices with yellow-gold surrounds later. A nipple marker is a precious-metal cone with a tritium plot at its centre. It pairs most often with the all-black aluminium insert. Black and brown dials show different ageing and service histories; condition should be judged from the individual watch.

The brown/rootbeer configuration pairs a brown sunburst dial with a brown-and-cream 24-hour insert. Some period brown dials show finish changes or flaking; originality and condition require inspection. No regional demand claim is asserted here.
The signature gold-rootbeer configuration is brown sunburst lacquer with applied yellow-gold nipple markers, paired with the brown-and-cream "rootbeer" insert. Brown dials can show surface damage or refinishing. The available sources do not establish a single failure pattern or a regional demand history that applies to every example.


The term "Sundust" belongs to a different surface treatment, the one on modern Everose Daytona, Datejust, and Day-Date production. The period GMT dial is called brown sunburst or rootbeer.

The serti is a factory gem-set variant on the standard 16718 architecture, a champagne or silvered ground carrying diamond hour markers and triangular rubies at 6 and 9 in place of the nipple markers and luminous plots. Auction and collector references document gem-set GMT dials with diamond markers and colored-stone accents, including ruby accents at the cardinal positions. That layout differs from common Submariner Serti examples. Bracelet pairing should be checked on each watch.

The cited 16713 and 16718 examples use diamond markers with triangular ruby accents on champagne or silvered grounds. Serti configurations are often seen on Jubilee bracelets, but bracelet pairing is not a factory rule.

The bezel itself is solid 18K yellow gold and the colour comes from the insert, a bidirectional 24-hour aluminium ring in one of two factory finishes, black or brown-and-cream "rootbeer." Pepsi (red and blue) is a steel 16710 option and never reached the gold case.

Aftermarket diamond-set bezels exist on 16718 cases. Factory origin cannot be inferred from the case reference or appearance and requires provenance and construction checks.
The reviewed major-house material does not establish a factory pavé bezel for the 16718. A diamond-set bezel on an individual watch requires case and provenance review; its presence alone does not establish factory delivery.

Two factory 18K bracelets fit the 16718. The Oyster 78368 is the three-link, sport-leaning option and turns up most often under black dials. The Jubilee 8386, sometimes with the hidden "Super Jubilee" clasp, is the five-link dress option and pairs most often with serti and rootbeer dials.

Clasps are 18K Fliplock Oyster or hidden-crown Jubilee. The bracelet codes date the bracelet and not the watch head, so a clasp dating later than the case points to a swap or a service replacement. Both bracelet families appear in period examples; the bracelet date and construction should be checked separately from the watch head.

The table records a small set of auction and catalogue examples. Current prices vary with metal condition, dial, bracelet, completeness, service history, and provenance; no general range or premium ladder is asserted here.
The auction and dealer record is smaller than the steel 16710 record. Results vary with dial, case condition, bracelet, papers, service history, and whether gem-setting or bezel work is original. The listed lots should be read individually; they do not establish a fixed price band or a universal serti premium.
