Corum Admiral Cup Seafender 48 deep dive, a true professional diving watch. According to FHS regulations, “Diver’s watches must be water resistant to 330 feet. They must also have a time controller and meet the standards provided by NIHS 92-11 (ISO 6425): brightness, shock resistance, magnetic resistance, and robustness.”
Seafender 48 is equipped with a 48mm x 18.9mm solid grade 5 titanium case, which can withstand pressures far greater than the ISO 6425 diving watch standard. In fact, the depth level of 1000 meters is actually ten times better.
The helium escape valve located between the 9 o’clock and 10 o’clock positions on the side of the case allows the watch to decompress after saturation diving. This is a feature required by true professionals, but not required by the ISO standard. Corum replica
The black dial and striking orange luminous markers and hands provide excellent visibility at night and, most importantly, underwater. Corum’s iconic twelve-sided curved sapphire crystal is a thicker version to ensure maximum water resistance. The internal anti-reflective coating allows a clear view of the dial under all lighting conditions.
The case is brushed, except for the lugs and the top of the crown are polished. The huge screw-in crown has a Corum key. The version number, waterproof rating and cheap Corum watch logo are engraved on the solid titanium back cover.
Powering Seafender is a COSC-certified Swiss-made 24-jewel automatic movement with an operating frequency of 28,800 vph (4Hz). The unidirectional rotating bezel with 120 clicks allows the wearer to accurately track dive time. A 24 mm wide black vulcanized rubber strap with a titanium buckle and pins can hold the watch firmly even when wearing a diving suit.
