Reference:16518: Difference between revisions

Line 111:

Auction and specialist sources document early floating and inverted-6 dials, later tritium markings, and the transition to Luminova and Super-LumiNova. Serial letters can help date an individual watch, but the 16520 chronology should not be copied into a complete 16518 factory table without a matching gold-case record.

The gold-case references share some dial changes with the 16520, while also carrying stone, mother-of-pearl, and gem-set options that are not ~~represented by~~ the steel reference’s standard dial sequence.

Champagne examples are common in the surviving record. White, black, mother-of-pearl, lapis, and sodalite examples are also documented, but the surviving auction set is not a complete factory option list.

Diamond-set hour markers are another documented gold-case option, with Karyn Orrico's "Gold Standard" piece for Sotheby's taking a 1993 S-serial 16518 as an example. Pavé bases and pavé-with-coloured-stones (ruby, sapphire) layouts exist on top of that, ~~generally on later production where~~ the ~~gem-set programme was running at higher volume. Which exact~~ pavé layouts ~~shipped from the factory~~ and ~~which were~~ aftermarket gem-setting is ~~uneven across the published literature~~; any pavé 16518 outside a Sotheby's or Phillips lot record needs case-by-case authentication.

Some listings describe tropical or faded dials. These should be assessed individually because dial ageing, refinishing, and the Patrizzi-style sub-dial-ring reaction are separate issues.

The 16518 case is 40mm in 18k yellow gold, the steel 16520 profile in solid gold. Lugs are heavier and fuller than on the manual-wind 6263YG and 6265YG that preceded it~~, and~~ the gold weight ~~makes the watch sit substantially heavier~~ on the wrist. Crown guards are integrated into the case as on the rest of the cal 4030 family. The 700-series Triplock crown sits at 3 o'clock, screw-down, sealing on three rubber gaskets. Water resistance is rated to 100m / 330ft.

Lugs are heavier and fuller than on the manual-wind 6263YG and 6265YG that preceded it; the gold case also changes the watch’s weight and balance on the wrist.

Water resistance is rated to 100m / 330ft.

The bezel is engraved 18k yellow gold with the tachymetre scale, and its font and scale chronology run in parallel with the steel reference. Earliest production carries over the 50-200 graduation with "UNITS PER HOUR" at 3 o'clock. The late-1989 transition moves the legend to 1 o'clock and runs the scale 60-400; from 1990 onward the legend stays at 1 o'clock with only 200 and 240 marked around 3 o'clock. Service-replacement bezels are the same forensic problem here as on the 16520, and a swap shows up as a bezel generation that does not match the dial.

== Bracelets, end links, and clasps ==

The 16518 is a leather-strap reference. Original-equipment delivery was alligator with an 18k yellow gold deployant buckle; the bracelet configuration is the 16528. Aftermarket gold Oyster fitments do surface on individual 16518 cases at the dealer tier, usually pulled from a 16528 or a Day-Date 18038 and refitted with an 18k yellow gold end-link to the 20mm 16518 lug spacing. They are not original delivery, and ~~the market prices them accordingly~~.

They are not original delivery and should be recorded as later fitments.

The deployant buckle is 18k yellow gold throughout the run. Rolex supplied an alligator strap with the gold deployant. Strap colour and originality vary among surviving examples, so the strap should be recorded separately from the clasp when assessing period-correctness.
