The Twenty~4 collection welcomes its very first complication: a perpetual calendar, one of Patek Philippe's most emblematic Grand Complications.

Thanks to ultra-thin self-winding 240 Q caliber, the non-gemset case has retained its elegant slimness. The calendar indications appear in three subdials, complemented by a moon-phase aperture, thus creating one of the most recognizable faces among Patek Philippe perpetual calendars.

The silver-toned dial is distinguished by its double vertically and horizontally satin-brushed finish reminiscent of shantung silk fabrics.
