Corum tackles an extremely complex equation in its new Admiral’s Cup Seafender 47 Tourbillon Chronograph. Its tourbillon is powered by an automatic caliber – in itself a rarity for this major complication – that in addition beats at a high frequency of 4 Hz as compared with 3 Hz for most classic tourbillons, an equally rare occurrence in the domain of Fine Watchmaking.

This remarkable oscillation speed of 28,800 vibrations per hour ensures exceptional precision, further reinforced by the automatic winding system ensuring a constant level of energy. The tourbillon performing one full turn every 60 seconds stages a fascinating show within its generous 14.08 mm carriage, while the small seconds spins around its circumference. The fact of being fixed to a micrometrical triple screw ensures finer adjustment and more constant precision.

The performances of this complex orchestration are backed by remarkable resistance, reinforced by a lever escapement featuring Gluycdur pallets. This rare degree of sturdiness that is indeed almost unheard of on a tourbillon model, makes the Admiral’s Cup Seafender 47 Tourbillon Chronograph particularly adaptable to daily living, since the watch can be freely worn in both urban and sporting contexts.

Clearly designed for daily wear, the Admiral’s Cup Seafender 47 Tourbillon Chronograph displays an aura of sporting elegance accentuated by the iconic nautical pennants on the inner bezel ring and the twelve-sided shape of the case.

Stylishly flaunting its generous 47 mm diameter, it is fashioned from aluminum with an anthracite grey ceramized coating. Its exploration of materials science led Corum to adopt the MAO (micro-arc oxidation) technique invented in Germany in the 1960s, but not industrialized until 2006 thanks to computerization and technological advances in the domain of equipment. The particularly innovative treatment used by Corum is accomplished by an electrical, physical and chemical transformation of aluminum immersed in a water bath.

This patented ecological method makes the watchcase truly exclusive and features a number of advantages. The ceramization technique gives aluminum a ten-times longer lifespan by making it harder than steel. It is also anti-abrasive and protects against corrosion, while lending an extremely beautiful aesthetic touch and an extremely pleasant feel.
