It really isn’t every day that something this special appears on the market. This Rolex Sea‑Dweller Ref. 1665 is being sold by the original professional diver owner.

Provenance

This watch carries exceptional, documented professional diving history, including:

• Used commercially for deep‑sea diving since purchase in 1976
• Documented evidence of dives in:
  • The Amazon Basin
  • The Baltic Sea
  • Commercial offshore projects around the world
• Known to have been worn during a salvage mission on the sunken ferry “Estonia”
• Diver’s badges and provenance documents available
• The sort of history almost never found with a surviving Sea‑Dweller

This is the type of Sea‑Dweller that collectors dream of — a watch that lived the life it was engineered for.

Our View

A genuine tool‑watch legend. The 1665 is already one of the most important Rolex dive watches ever made, but an example with this level of real diving history, original diver ownership, multi‑decade Rolex service trail, and confirmed use on major salvage missions makes it genuinely irreplaceable. In our view, this is not only excellent value but also an exceptional long‑term investment.
