The story behind this Corum Admiral's Cup Seafender
The story behind this Corum Admiral's Cup has its roots in the world of ocean racing. The brand has developed this collection with a distinctive dodecagonal case designed to incorporate the flags of the International Code of Signals. With reference number 753.231.06/0371, the range is geared towards diving under the name Seafender. This model stands out for its left-handed configuration. This design offers an ergonomic advantage to right-handers as it prevents the controls from hitting the back of the hand when the wrist is bent. This limited edition of 888 pieces adapts the nautical instrument to the demands of underwater use.
Case, movement and strap of this Admiral’s Cup Seafender
The design of this timepiece centres on a 50 mm titanium case. This lightweight metal, with a brushed finish, is paired with matt black vulcanised rubber on the bezel and the off-centre controls on the left-hand side. A helium escape valve is positioned at 4 o’clock to ensure water resistance to 300 metres. The matt black dial features luminescent applied hour markers and a flange adorned with monochrome flags. The display comprises a chronograph sub-dial at 9 o’clock and a compass-rose-shaped seconds hand at 3 o’clock. The self-winding mechanical movement, calibre CO 753, powers the watch with its 27 jewels. It offers a 48-hour power reserve and operates at a frequency of 28,800 vibrations per hour. The textured rubber strap fastens with a titanium pin buckle.
Why this Corum watch
This model catches the eye with its balance between a large case size and optimised comfort, achieved by the reversed layout of its controls. The pre-owned market offers the chance to acquire this numbered series, which is no longer available through official channels. The owner will appreciate the technical contrast between the lightness of the titanium construction and its striking presence on the wrist. The monochrome aesthetic gives this timepiece a subtle, contemporary look.
