To celebrate its 60th anniversary in 2015 Corum has created a timepiece that reimagines the iconic haute horlogerie complication in a profound yet practical manner.

With a tourbillon carriage mounted on enlarged ceramic ball bearings for resilience, the movement of the Admiral’s Cup Legend 42 Flying Tourbillon has the bridge and base plate machined from stainless steel, instead of the typical, softer brass. Only with the stiffness and strength of steel were the movement’s designers able to achieve the remarkable visual effect of the tourbillon seemingly floating as it makes one revolution a minute.

With the base plate and bridge terminating at four and eight o’clock on both sides of the movement, the tourbillon appears to be suspended in mid-air. But it is actually tethered to the movement by the two slender steel arms that are part of the bridge.
Finished with a fine straight graining, the base plate is visible through the smoked sapphire dial with a red gold galvanized Corum logo at nine o’clock. Just above it is the fan-shaped retrograde date display. Centered on a snail shaped cam that controls the retrograde function, the date hand crisply jumps from one day to the next, until it reaches the 31st. Then it jumps straight back to 1, marking the start of a new month.

From the rear, the view through the sapphire display back is equally panoramic. The caliber CO 016 is equipped with a micro-rotor decorated with the Corum logo in 18k red gold. Just 17 mm in diameter, the micro-rotor has a winding efficiency of two, meaning it can wind the mainspring to its full autonomy of 72 hours.

The facetted, skeletonized and gilded hour and minute hands, in red gold, are elegantly legible against the smoked grey sapphire dial. The chapter ring bears the 12 nautical pennants. Positioned as the hour markers, the pennants are a subtle reminder of the nautical heritage of the Admiral’s Cup. Echoing these pennants is the 12-sided bezel of the red gold case. With a 42 mm diameter and just 13 mm high, the case is constructed to be elegant yet robust, with a water resistance of 50m.

The watch is fitted with a brown crocodile leather strap.
