Corum Admiral’s Cup Legend 42 Tourbillon Micro-Rotor


Corum Admiral's Cup Legend 42 Tourbillon Micro-Rotor rose goldCorum has added a tourbillon model to its yachting-inspired Admiral’s Cup collection of watches — specifically, a tourbillon with automatic winding via a microrotor — a timepiece whose steel-case version retails for under $50,000.

The Admiral’s Cup Legend 42 Tourbillon Micro-Rotor has a 42-mm-diameter case and the 12-sided bezel, with 12 nautical pennants indicating the hours, which has become familiar to fans of the Admiral’s Cup line, first introduced by Corum in 1960. The case has sapphire crystals in the front and back, and is water-resistant to 30 meters.

The dial, in silvery gray, has an outer ring adorned with a snailed pattern and 11 applied hour indices — gilded in the rose-gold model, and rhodium-plated in the stainless steel model. The hour indices line up with the nautical pennants, which are transferred on the dial’s flange. The inner ring of the dial has a barleycorn pattern and an applied Corum logo beneath the 12 o’clock position.

The dauphine-style hands for the hours and minutes are openworked, faceted and, as with the indices, rhodiumed for the steel version and gilded for the gold one.

The watch’s centerpiece, its 12-mm tourbillon carriage, is located at 6 o’clock. It features an openworked tourbillon bridge that is either gilded and polished (rose-gold model) or rhodiumed and polished (steel model). The small seconds tick away in rhythm with the movement of the tourbillon.

At the heart of the watch is the automatic caliber CO503, which beats at a frequency of 28,800 vph and boasts a 60-hour power reserve. It’s powered by a 17-mm microrotor that is decorated with circular côtes de Genève and bears an engraved Corum key emblem. These and other decorative touches are visible through the screwed-down sapphire caseback, including côtes de Genève on the upper part of the plate and vertical satin-finishing on the lower part, as well as a Corum logo engraved on the bridge.

Tourbillon watches with automatic movements are rare, and those powered by microrotors are rarer still. With this in mind, the U.S. retail price on the Admiral’s Cup Legend 42 Tourbillon Micro-Rotor is a somewhat pleasant surprise: only $43,000 for the stainless steel version and $59,500 for the rose-gold model — well below the going rate for many other Swiss-made tourbillon watches. The watch is limited in production — only 15 pieces will be made in rose gold, only 30 in a rose-gold-steel combination (not pictured), and 75 in steel.

    Very Nice! but a yachting-inspired watch with 30m only? hmm that’s a bit silly in my opinion, but still a great design and i love the use of a micro-rotor!
