Rolex Sea-Dweller – Ref. 16660 “Triple 6” – “Nice Patina Dial” – Year 1986 – Official Rolex Service 2023 – Watch Only

The Rolex Sea-Dweller 16660 “Triple 6” is a landmark model in the evolution of Rolex’s professional dive watches. Produced in the mid-1980s, it introduced major technical improvements over its predecessor, making it one of the most appreciated transitional references among collectors.

This example, with a 9-million serial (1986), features a highly attractive “nice patina dial” with naturally aged, warm and uniform lume on markers and hands, giving the watch exceptional vintage character. The bezel remains true to its original construction: stainless-steel bezel with black anodized aluminum insert, as used in pre-Cerachrom production.

Crafted in Oystersteel, the 16660 marked a technological leap with the introduction of sapphire crystal, a redesigned helium escape valve and increased water resistance up to 1,220 m, reinforcing its status as a professional tool watch for deep diving. The bracelet retains its period-correct clasp with code J12.

Inside beats the Rolex calibre 3035, an automatic COSC-certified movement operating at 28,800 vph and offering the convenience of the quickset date function, along with improved stability and reliability—key strengths of this generation.

The watch underwent an official Rolex service in 2023, ensuring optimal performance according to factory standards.

This piece is offered watch only, without box or papers.
