Four years of R&D, four barrels, four balance-springs, four pushes on the single push button and 437 parts serve to activate the first chronograph measuring two distinct times and the difference between them: the Tambour Twin Chrono. Designed by the Fabrique du Temps Louis Vuitton, this unusual horological complications proves particularly timely and apt for the brand which is serving as official timekeeper for the Louis Vuitton Cup and the America’s Cup, taking place this summer in San Francisco. The format of the regatta requires the ability to measure the race time of both participants, as well as the difference between their respective performances. This highly sophisticated movement consists of two column-wheels. The time indication is adjusted using the crown at 2 o’clock and features automatic winding, while manual winding (via the crown at 4 o’clock) supplies the energy for the double-chronograph function. The pusher at 7 o’clock makes this ingenious instrument incredibly easy to use: the first push takes place at the start of the race; the second memorises the time taken by the yacht to cross the finish line first (appearing on a counter at 7 o’clock) and triggers measurement of the time difference with the next boat; while the third indicates the duration of the second yacht’s race (at 4 o’clock) as well as the difference in minutes (white hands) and seconds (red hands) between the two (at 12 o’clock). A final push resets the counters to zero ready to time a new match. In an ultimate touch of refinement, this limited edition world-first function appears against an exceptionally aesthetically intense Grand Feu enamel background.
