	The cleanest documented professional-diving 16660 provenance chain is the Sotheby's Geneva 2026 Lot 92 Godart to Johansson chain detailed in the COMEX auction anchors. Two divers across 23 years, with the 1991 transfer at 450m North Sea saturation as a documented historical-event marker.		The cleanest documented professional-diving 16660 provenance chain is the Sotheby's Geneva 2026 Lot 92 Godart to Johansson chain detailed in the COMEX auction anchors. Two divers across 23 years, with the 1991 transfer at 450m North Sea saturation as a documented historical-event marker.

	~~==Tertiary-source corrections==~~

	"16660 used cal 3135 from 1988" is wrong. Every factory 16660 carries cal 3035. The cal 3135 launched in 1988 in the Datejust and Submariner 16610 but entered the Sea-Dweller line only with the reference change to the 16600 in 1989. Italian Watch Spotter's caliber timeline carries the error.

	"Wikipedia 16660 dimensions and movement" is wrong. Wikipedia's English Sea-Dweller article attributes 1989-2009 production, cal 3135, 15.5mm thickness, and ceramic bezel to the 16660. That's the 16600 spec set mislabelled (and the 16600 didn't have a ceramic bezel either; that's the 116600). Two-generation conflation.

	"Matte = early, glossy = late" is broadly true with documented exceptions. Late matte examples surface in the 8.0M-8.5M serial range (1983-early 1984), overlapping with early glossy production. First-batch matte COMEX cases (3001-3099) occasionally carry glossy MK3 dials, documented as service replacements rather than factory-original configurations.

	"Spider crazing is UV damage" is incomplete. UV and thermal cycling accelerate the failure, but the underlying cause is Stern's lacquer chemistry; the dials were defective from delivery and the environment merely exposed it. Rolex paid for service replacements freely, which itself confirms manufacturer-defect liability.

	"Triple Six refers to Satanism" is tongue-in-cheek collector chatter, not the etymology. The nickname derives from the reference number's three sixes. Rolex's own period marketing called it the "Sea-Dweller 4000."

	"All factory 16660s are SCOC chronometers" is only partly accurate. The dial says SUPERLATIVE CHRONOMETER OFFICIALLY CERTIFIED on glossy SCOC dials; first-batch matte COMEX (3001-3099) carries a two-line text omitting SCOC. Every 16660 is COSC-certified through the cal 3035 internally, but the dial print convention differs by batch.

	"James Cameron wore a Sea-Dweller for the Mariana Trench dive" is only partly accurate. Cameron wore an experimental Deepsea Challenge (51mm prototype). Not a 16660; not even the production 116660, but the prototype that the 116660 evolved from. The 116660 D-Blue Cameron commemorative followed in 2014 as a tribute, not as the watch Cameron actually wore on the dive.

	"50 vs 100 matte COMEX 16660s" is contested. Phillips says "fewer than 100." Some collector traditions read the 3001-3099 batch as up to 99 units; some sources count only 50 confirmed matte issuances. The 100-unit reading has the cleanest published support; the 50-unit reading appears in dealer summaries without primary documentation.
