Christophe Claret presents the Kantharos, a single-pusher chronograph with a cathedral gong strike that resounds with each change of the automatic chronograph function. The watch acoustically signals start and stop before they are read off on the wrist. The column-wheel friction system, inspired by automobile mechanics, prevents the hand from jumping when the chronograph starts, making the measurement more accurate. Useful, functional and playful at the same time, the device plays on sensory, manual and acoustic interactivity between the instrument and its owner. In addition to this important complication, the timepiece houses a constant-force escapement, visible at 6 o'clock on the dial side. The latter, in layers, is traversed by the hour and minute hands, retrograde and jumping respectively: made of titanium and rubies, the hands are coated with luminescent material. The counters, inspired by the instruments on board an aircraft, offer an original disc display system: on the first, in sapphire, the numbers are displayed; on the second, black and white, below, is a red indicator. The movement, a mechanical self-winding movement, uses the first components made of M-15X, a material produced by a sintering process, a manufacturing technique that guarantees a homogeneous microstructure and an extremely fine grain. Housed in a 45-millimetre diameter titanium and white gold case and visible through the sapphire crystal back, the movement was designed, developed and assembled in-house (558 components, 75 jewels, 48-hour power reserve).
