CORUM Admiral's Cup AC-One 45 Skeleton


Mechanical exploration

With its new Admiral’s Cup AC-One 45 Squelette, Corum offers a full immersion into the heart of its intricate horological workings. The airy architecture of a finely openworked mechanism, together with the transparency of remarkably modern date disk and the lightness of the titanium clothing the case with its iconic lines, all contribute to earning this new model a place of its own within the world of Fine Watchmaking.

Right from its launch in 1960, the Admiral’s Cup asserted itself as a frontrunner in the field of design with its powerful style emphatically defined by a twelve-sided bezel unlike any other. It was the kind of model destined to find its way through the decades with the
tranquil assurance of those that have their finger firmly on the pulse of time and are able to anticipate trends. Ever since, it has consistently surprised observers by its ability to show up in consistently avant-garde compositions.

The new Admiral’s Cup AC-One 45 Squelette is no exception. At the heart of its grade 5 titanium case beats a high-precision (28,800 vph) mechanism: automatic Caliber CO 9000.

For the first time, this movement with its 42-hour power reserve appears in an entirely openworked architecture that draws all eyes to explore the heart of its intricate gear trains with their resolutely contemporary finish. Its power of attraction is further heightened by the absence of a dial, while a highly original transparent date disk bearing fully visible numerals lends an even more modern touch to the overall effect.

While their base is applied on an anthracite-colored dial, the Superluminova-enhanced hour-markers are extended to the point where they appear to be levitating around the rim of the date disk. This play on contrasts and depth effects is accentuated by the galvanictreated
inner bezel ring, duly framed by the Admiral’s Cup iconic nautical pennants.

The generously sized 45 mm grade 5 titanium case with its layered construction is topped by its famous twelve-sided bezel, while black PVD inlays are strategically placed between the various elements to create an even more powerful effect. While the titanium features
alternating polished surfaces and satin-brushed side plates, the sapphire crystal bears the metallized Corum logo. The equally transparent caseback offers its own perspective on the CO 9000 movement, and particularly on the finely openworked, Corum-personalized oscillating weight. Alongside its remarkable style, the case also boasts impressive water resistance to 300 meters. An extremely elegant black crocodile strap fitted with a grade 5 titanium folding clasp sets the perfect finishing touch to this new Admiral’s Cup AC-One 45
