THE HEART OF THE
SEA-DWELLER MODELS
OYSTER PERPETUAL
SEA-DWELLER
The Oyster Perpetual Sea-Dweller,
guaranteed waterproof to a depth of
1,220 metres (4,000 feet), was designed
to accompany the pioneers of deep-sea
diving. Its helium escape valve and
unidirectional rotatable bezel make it a
true professional diving instrument.
Its dial offers exceptional legibility thanks
to the Chromalight hour markers and
hands. The 43 mm case is a paragon of
robustness. TheTriplock winding crown,
with a triple waterproofness system,
is protected by a crown guard that is
an integral part of the middle case.
The sapphire crystal, with a Cyclops lens
at 3 o’clock, is virtually scratchproof.
The Oyster Perpetual Sea-Dweller is
equipped with a self-winding mechanical
movement entirely manufactured
byRolex.
The Oyster Perpetual Sea-Dweller
features an Oyster bracelet with
an Oysterlock safety clasp, the Rolex
Glidelock fine-adjustment system and,
depending on the model, a Fliplock
extension link.
