Sea-Dweller
Built for 1,220 meters, worn on wrists
The Sea-Dweller was born in 1967 from the needs of saturation divers — specifically the helium-escape valve required to survive decompression in pressurized habitats. The modern 43mm reference brings back the red 'SEA-DWELLER' text of the original 'Single Red' prototype, paired with a 70-hour movement.
