If the Submariner is a workhorse underwater, then the Rolex Oyster Perpetual Sea-Dweller 4000 is the entire cavalry. The Sea-Dweller, introduced in 1971, is a heavier-duty version of the Submariner, with a thicker case and crystal.
The Sea-Dweller incorporates a helium escape valve for withstanding decompression, and is guaranteed to operate perfectly at 4000 feet or 1220 meters of water depth.
Other features include:
- 40mm - all steel
- Black dial
- Black unidirectional rotating bezel
- Perpetual rotor self-winding movement
- Oyster fliplock bracelet with extension links
- Helium escape valve
Chosen time and again by professional divers and especially saturation divers, this watch thrives where few others can even survive.
