In beautiful condition, this is the vintage Sea-Dweller ref. 1665 aka 'Great White' with super-domed Plexiglas. 

From the first year of production (1977), this Mark I dial was the first all white print SD. Unmistakable vintage warmth and the combination of the matt charcoal dial, rich creamy tritium hours markers and matching hands, make for a super collectable dive watch. Inside the caseback are numerous etchings from Rolex watchmakers after routine servicing. Fitted to the 93150 Oyster Fliplock bracelet, powered by the automatic 1570 movement, and covered by our 2 year comprehensive warranty.
