Endowed with a 46-hour power reserve, this Chargé d’Affaires watch is equipped with an entirely exceptional movement: the very same caliber that once beat at the heart of the original model in 1956. This historical movement has been entirely restored using vintage tools and techniques, while meeting current standards of quality and finishing. This mechanical hand-wound Caliber CO 286 is fitted withtwo barrels, each with its own winding crown: one to control the hands, and the other the alarm. This arrangement makes it possible, alongside the central hour, minute and seconds hands, to power an alarm sounding for over 12 seconds on a particularly clear note. This mechanical gem is visible through the case-back and reveals the sound bridge engraved with the inscription “1956 – Chargé d’Affaires – 2012”.
