Complications Men's - 5205R 40 mm, rose gold with olive green alligator-skin strap, self-winding caliber 324 S QA LU 24H/206 with annual calendar | Reference Number PP310171

Patek Philippe presents a variation of its patented annual calendar with this model, reference 5205R-011. 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 controlled by self-winding caliber 324 S QA LU 24H/206. The annual calendar needs 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 rose gold, and supports an olive-green, two-tone dial with a subtle black gradient, and ultrafine sunray decoration for emphasis.
