CORUM Admiral’s Cup Challenger 40 Chrono Diamonds

The CORUM Admiral’s Cup Challenger 40 Chrono Diamonds is an elegant and sporty timepiece in a 40 mm diameter that perfectly suited to feminine wrists of those who love for adventurous life.

Responding to the new trends, CORUM has created a subtle alliance in the Challenger 40 Chrono Diamonds between the signature characteristics signaling its belonging to the Admiral’s Cup line, and a set of delightfully refined feminine details.

The three counters are adorned in Polynesian mother-of-pearl, black or white according to the version. The twelve-sided bezel sparkles with 66 diamonds (totaling 0.92 carats), while the openworked central hour and minute hands create a light, dynamic aesthetic.

Finally, the Corum key serving as a counterweight to the central sweep seconds hand sets the perfect finishing touch to this exquisitely delicate watch face.

However, it is perhaps the chronograph function that best expresses the authentic strength of this timepiece. Equipped with a mechanical automatic movement with a 42-hour power reserve – COSC chronometer-certified Caliber CO984 – the CORUM Admiral’s Cup Challenger 40 Chrono Diamonds displays the hours, minutes, small seconds at 3 o’clock, along with a sweep seconds hand, a 30-minute counter at 9 o’clock, a 12-hour counter at 6 o’clock and a date window at 4.30.

Dressed in a polished and satin-brushed steel case fitted with a rubber strap, or in 18-carat red gold with a crocodile strap and gem set dial, this extremely chic chronograph is available in a choice of black or white. It is water-resistant to 100 or 50 meters depending on the version.
