newcomer to the Extreme line. Its helium valve, its secure rotating bezel and its hyper-luminescent hour-markers
make this imposing and sophisticated watch a genuine instrument for professionals.
Created in 1960, the Admiral’s Cup watch by Corum is an authentic icon for all devotees of nautical sports
and diving. Its twelve-sided bezel and its nautical pennants have been forging a legend for over 50 years.
This emblematic collection is now built around three specific worlds: the Heritage line with its elegant design
and classic functions; the sporty and distinguished Competition line suited for wear on all occasion; and finally
the sturdy and sophisticated Extreme line designed for adventurers. The latter family now welcomes the new
Admiral’s Cup Seafender 48 Deep Dive model, water-resistant to a full 1,000 meters.
The term “diver’s watch” is strictly governed by the corresponding ISO standards. The Admiral’s Cup Seafender
48 Deep Dive meets all these essential criteria: its imposing case in grade 5 titanium, measuring 48 mm in
diameter and 18.9 mm thick, is fitted with a screw-down crown and can withstand 100-bar pressure corresponding
to a depth of 1,000 meters. This authentic diving instrument is also equipped with a decompression valve placed
at 9.30 on the case, just below the inscription “1000M”. This device serves to vent the helium that may build up
inside a watch during a prolonged stay in a hyperbaric chamber. Without this valve, the gas would be liable to
expand and cause irreversible damage.
Careful monitoring of immersion times is crucial when diving. Thanks to its 120 graduations, the unidirectional
rotating bezel of the Admiral’s Cup Seafender 48 Deep Dive is accurate to the nearest half-minute. Moreover, in
order to guarantee perfect readability even in the darkness prevailing at great depths, the hands and hour-markers
are covered, depending on the version, with either black superluminova or an even more luminescent bi-light
This generously sized watch is equipped with a movement to match its ambitions: automatic Caliber CO947
endowed with a 42-hour power reserve and chronometer-certified by the COSC. It displays central hours and
minutes, small seconds at 9 o’clock, and the day and date at 3 o’clock.
The Admiral’s Cup Seafender 48 Deep Dive comes in two versions: the first, with its polished and satin-brushed
grade 5 titanium case and bezel and its orange hour-markers is available in a 200-piece limited series; while the
second, featuring a PVD blackened grade 5 titanium case and 18-carat red gold bezel, is to be issued in an 100-
piece limited edition. Both are equipped with a black vulcanized rubber strap fastened by a titanium pin buckle.
