CORUM Admiral’s Cup Seafender 47 Tourbillon GMT

The Admiral’s Cup Seafender 47 Tourbillon GMT by CORUM combines sporty lines and benchmark horological complications, namely a tourbillon and a dual time zone.

With its tourbillon at 10.30 and the GMT function at 6 o’clock displaying the second time zone, this Admiral’s Cup Seafender powered by the automatic C0397 movement, is entirely in tune with the noblest traditions of Fine Watchmaking.

The first automatic tourbillon model in the Admiral’s Cup collection with its ultra-precise movement beating at the frequency of 4 Hz (28,800 vibrations per hour), this sports tourbillon – which is particularly resistant thanks to its micrometrical screws – is also distinguished by its “turbine” design. Beneath each “turbine”, a wheel moves in the opposite direction to the effect created by the turbine.

These intriguing shapes work their magic with a tourbillon that appears to be floating in mid-air beneath a V-shaped bridge and a tourbillon carriage enhanced by the Corum key symbol.

The extremely readable hour and minute dual time-zone display, positioned at 6 o’clock, is complemented by the three-quarter circular day/night indicator at 7.30.

The pointer-type date indication appearing in a subdial at 3 o’clock sets the perfect finishing touch to the harmonious visual appeal of this sophisticated and elegant watch endowed with a 50-hour power reserve. Note the discreet presence of a pusher at 4 o’clock designed for smooth and easy adjustment of the dual time-zone display.

With its generously sized 47 mm diameter, the Admiral’s Cup Seafender Tourbillon GMT is distinguished by its two logos, Corum and Admiral’s Cup, engraved directly on the inner face of its anti-reflective sapphire crystal – a feature also found on the screw-down back.

The model is available in two versions. The first is the epitome of originality and lightness, with its case, bezel and crown guard in 7075 aluminum featuring an electro-plasma treatment that makes this material harder by endowing it with a light yet ultra-sturdy character. The ceramization (electro-plasma) process gives the 7075 aluminum a dark gray shade.

The dial is adorned with a Clous de Paris motif and rhodium coated hour-markers, as well as skeleton hour and minute hands, a dauphine-type date pointer and rhodium coated dual time-zone hands enhanced with superluminova for nocturnal readability.

The collection’s characteristic nautical pennants are positioned between the hour-markers and the inner bezel ring. The 18K gold version features hands and hour-markers in the same material and also superluminova treated.

Both models are water-resistant to 50 meters and fitted with a crocodile leather strap complete with a folding clasp in grade 5 titanium or 18K gold, engraved in both cases with the Corum logo.
