Engineered to be heard.

Every calibre tells time; very few sing it. The SMA-HH02 is the most complex movement ever conceived within Le Cercle des Horlogers — a hand-wound grand complication uniting a carillon minute repeater with a 60-second flying tourbillon. At the slide of a lever, a mechanism of hammers and gongs transforms the silent geometry of gears into sound, striking the hours, quarters and minutes with the clarity of a miniature bell tower. Around it, 536 components work in concert, each one designed, decorated and assembled by hand in our Geneva-area manufacture. It is not merely an engine of precision. It is an instrument.

Look closer. Measuring 34.40 mm in diameter and 9.80 mm in height, the SMA-HH02 beats at 3 Hz (21'600 vibrations per hour) on 51 jewels, with a 72-hour power reserve and an angle of lift of 52°. The finishing speaks the language of haute horlogerie: Côtes de Genève traced at 1.5 mm, cage bridges hand-bevelled and polished with drawn flanks, a hooped finish crowning the cage bridge base, and a diamond-bevelled balance wheel plated in 3N gold. The flying tourbillon, cantilevered and unobstructed, completes its revolution every sixty seconds — gravity's answer, rendered visible.
