The very first complication in the Twenty~4 collection and the first non-gem set round Twenty~4, this rose gold perpetual calendar is distinguished by its dial in an elegant sunburst olive green color that is both subtle and modern. Beating at the heart of the entirely polished case is self-winding 240 Q caliber, an ultra-thin movement endowing the watch with an elegantly slim profile. The complete day-date-month calendar automatically takes into account the varying lengths of the months, including leap years. The rose gold bracelet features a patented fold-over clasp secured by four independent catches.
