CORUM Admiral’s Cup AC-One 45 Double Tourbillon


Chronometric precision accelerator 

Regarded as the epitome of sporting chic in the noblest sense of the term, the Admiral’s Cup now welcomes an eminently complicated new movement: hand-wound Caliber CO 1008. This exclusive mechanism features nothing less than a double tourbillon, combined with a retrograde date and an ingenious time-adjustment system.

For over two centuries, the tourbillon has been a symbol of chronometric precision. Designed to compensate for gravity-induced rate variations in vertical positions, it remains one of the major complications that is the hardest to produce. Corum has achieved an authentic tour de force in equipping its new Caliber CO 1008 with not just one but indeed two parallel-mounted tourbillons, dedicated to ensuring remarkable reliability backed by a generous 72-hour power reserve. And the feat doesn’t stop there, since this masterfully
orchestrated mechanism is fitted with a retrograde date and a particularly innovative timeadjustment device. Simply by pressing the crown pushbutton, the wearer can bring the minutes hand instantly to the 12th index so as to set the exact time – and this can be done up to five minutes before or after a full hour.

Contemporary and sophisticated
Embodying an authentic horological challenge, Caliber CO 1008 finds the perfect stagesetting in the iconic twelve-sided case of the Admiral’s Cup – born in 1960 and redesigned in 2013, while remaining staunchly true to the signature codes that have earned it legendary status. Based on a contemporary architecture featuring alternating polished and satin-brushed finishes, its layered construction comprises black PVD-coated titanium inserts appearing in turn between the case back and middle and then between the bezel and the case middle – all contributing to a masterfully structured aesthetic approach.

Available in 18K red gold or grade 5 titanium, the case of the Admiral’s Cup AC-One Double Tourbillon stylishly displays a generous 45 mm diameter enhanced by an immediately recognizable design. Clearly cut out for adventure, it is endowed with impressive water
resistance to a depth of 300 meters.

The dial swept over by luminescent hands and hour-markers is adorned with an exclusive design specially developed for Corum: the split pomegranate motif. Forming small diagonally-incised squares, this composition creates an elegant depth effect accentuated by the inner bezel ring stamped with the emblematic nautical pennants of the Admiral’s Cup collection.

While the two tourbillons spin on the lower part of the dial, a dynamic red arrow points to the retrograde date segment appearing on the upper part like an extension of the two carriages.

The dazzling style of the Admiral’s Cup AC-One 45 Double Tourbillon continues on the bridge side, where the transparent back reveals the beauty of the mechanical caliber oscillating at a frequency of 21,600 vibrations per hour (3 Hz). The movement’s modern execution features a horizontal satin-brushed finish and anthracite grey engravings.

Mounted on a mainplate made of cupro-beryllium, a particularly wear-resistant copperbased alloy, it testifies to a determination to endow exceptional horological complications with remarkable long-term reliability. The Admiral’s Cup AC-One 45 Double Tourbillon is thus set to continue, for many years to come, beating to the pulse of watchmaking mingling outstanding performance and powerful emotions.
