Rolex launched its first Sea-Deweller in 1967, a watch that incorporated a patented helium escape valve that regulated the pressure inside the watch case during deep water dives.
The 2017 Oyster Perpetual Sea-Dweller is likely to spend more time in board meetings than below the ocean, but it is still a technical divers’ watch, waterproof today to a depth of 1,220 metres (4,000 feet).
The new Sea-Dweller has a larger, 43 mm case and the new calibre 3235 movement.
New details not seen before on Sea-Dwellers include a cyclops lens to help read the date at 3 o’clock and the Sea-Dweller name being depicted in red for the first time.
