Diver watches
Specifically tuned to the needs of divers
wristwatch-type. To maximize water resistance
belongs to a single counter-clockwise rotating
bezel for measuring the dive time and the best
possible visibility under water. Another useful
feature is a scratch-resistant watch glass (sapphire
glass), because the scarring Diving a Past
articles can not be excluded.
Before the dive, the diver is the zero mark of the
bezel to the position of the minute hand. When
looking at the clock may then immediately past the
diving time to read. The reason for the adjustment
counter-clockwise only safety lies in thinking: If
the bezel rotated during the dive by mistake, then
they will always show an apparently greater
immersion time, and that the divers in the light
of the decompression time is always on the safe
side.
History
The merit of this epochal development to the House
Rolex, has with the invention of the screw housing
(1926) resolved once and for all the problem of
leakage. As a result of the implementation of the
theoretical studies towards a practical use was
the Oyster, which has practically become a synonym
for waterproof watches. But the name already
points out the special feature of this timepiece.
Furthermore, this clock was in 1927 in the center
of one of the first spectacular advertising
campaigns in the history of the wristwatch. The
athletic performance of Mercedes Gleitze who swam
the Channel in 15 hours, then filled the pages of
journals and magazines. On her wrist while she was
wearing a Rolex Oyster, the work on their arrival
on the other side of the canal is still perfect.
The interest of collectors for diving watches focuses, in addition to
historical examples, in particular models that represent in different ways
the concept of "sportiness". Doubtless this is part of the image of these
timepieces. The major watch houses are trying in various ways, which to be
fair. Patek Philippe Carlier, or some combination to prove the concept of
tightness with an original design, as the Nautilus and the Pasha. The Omega
Seamaster and the Submariner or Sea-Dweller Rolex's mainly emphasize the
technical component. All these models have in addition vorschraubter crown
and housing also has a one-way rotating bezel to the dive time to calculate.
