ROLEX SEA-DWELLER Reference 16600 – Year 1990 – Excellent Condition – Tritium Dial, Hands & Bezel Pearl

We are delighted to present you this excellent Sea-Dweller 4000 in stainless steel on its Oyster bracelet.

For sale is a highly sought-after Rolex Sea-Dweller 16600 from 1990, a classic tool-watch that perfectly represents Rolex’s heritage in saturation diving. This example is in excellent condition and stands out with its original tritium dial, matching tritium hands, and tritium bezel pearl—a detail increasingly rare and highly appreciated by collectors. The warm patina that develops on tritium over time adds unmistakable vintage charm while preserving full legibility.

Designed for extreme underwater environments, the Sea-Dweller 16600 is equipped with Rolex’s iconic helium (gas) escape valve. This valve was developed in collaboration with professional saturation divers and allows helium molecules that accumulate during deep-sea missions to safely escape from the case during decompression. This innovation prevents crystal blow-outs and ensures the watch remains perfectly sealed and ready for the next dive—proving why the Sea-Dweller has long been trusted by diving professionals across the world.

With a robust 40 mm steel case, unidirectional rotating bezel, and the reliable Rolex calibre 3135 automatic movement, this reference delivers both durability and precision. Whether worn as a daily companion or preserved as a collectible piece, this Sea-Dweller is a timeless icon that only becomes more desirable with age.

A fantastic opportunity to acquire a vintage Sea-Dweller with full tritium lume, excellent overall condition, and the unmistakable character only early 16600 models offer.
