Rolex Sea-Dweller 1665 - MK1
rare MK1 execution - flawless dial - beautiful look
SoldCompared to the Submariner, the Sea Dweller was always Rolex's more professional diving watch. In addition to the higher water resistance, the Sea Dweller had the newly developed helium valve. This allowed the inner pressure in the watch to be diminished faster during the decompression and thus the breaking of the crystal could be avoided, which was the case with the Submariners. There are also visual differences to Submariner such like a larger case and the absence of the Cyclops lens above the date at 3 o'clock.
