Rolex Oyster Perpetual Sea-Dweller 43mm, Reference 126600-0002

The new Rolex Sea-Dweller 43mm is a latest addition to the Swiss brand’s deep diving watch family. It belongs to the ref. 126600 series.

In 2017, Rolex released a new generation of its Sea-Dweller watches as a replacement of the Reference 116600 series. Featuring a 43mm diameter case in Oystersteel and the self-winding 3235 calibre, the Sea-Dweller Ref. 126600 maintains a water resistance of 1,220 metres or 4,000 feet.

The first model from this generation is Reference 126600-0001, which features a black dial with red SEA-DWELLER inscription as a tribute to the Single Red prototypes produced in the 1960s. In 2021, Rolex replaced this model with a new reference 126600-0002.

The majority of the aesthetic and technical characteristics of both references remain same. A notable difference is that the new Rolex Sea-Dweller 126600-0002 comes without the Fliplock extension links.
