Complications Men’s - 5205G 40 mm, 18k white gold with black alligator-leather strap, 324 S QA LU 24H/206 automatic manufacture caliber with moon-phase display and annual calendar | Reference Number PP310156

Patek Philippe presents a variation of its patented annual calendar with this model, reference 5205G-013. It arranges apertures in an arc to indicate the day of the week, date, and month. The moon phase with integrated 24-hour display at six o’clock is especially prominent. The complex mechanics are governed by a self-winding 324 S QA LU 24H/206 caliber. The annual calendar need only be corrected once per year when February changes to March. The case, meanwhile, measures 40.0 x 11.36 millimeters, is made of 18k white gold, and supports a two-tone dial with a simple appearance, subtle black gradient, and ultrafine sunray decoration for emphasis.
