UNIDIRECTIONAL
ROTATABLE BEZEL
The Oyster Perpetual Deepsea Challenge
allows divers to safely monitor their
dive time thanks to the unidirectional
rotatable bezel. This bezel is fitted
with a 60-minute graduated Cerachrom
insert made of ceramic, a material that
is resistant to environmental effects.
Before the dive
Before beginning your descent, turn
the bezel until the triangle on the
graduation is opposite the minute hand.
It indicates the beginning of the dive
and is visible in the dark thanks to a
phosphorescent capsule.
During the dive
The duration of the dive is indicated on
the graduation on the Cerachrom insert
by the minute hand.
For safety reasons, the bezel turns only
counterclockwise. Accidental rotation
of the bezel can therefore only shorten
the dive time.
