The Patek Philippe annual calendar in 18ct white gold, with customary 21ct yellow gold rotor (caliber 315 S QA, comprising 316 parts).
“The patented mechanism was first introduced in 1996 and makes it unnecessary to adjust the date display throughout an entire year. Only when February changes to March does the owner need to make a manual adjustment. Unlike the classical mechanism of the perpetual calendar, whose functions rely on jumper springs, cams and racks, the annual calendar is based almost entirely on a rotary mechanism. The wheels and pinions of this tirelessly turning mechanism run with minimal friction; the profile of the switching teeth are crafted with the utmost precision, thus achieving the best possible transfer of energy.
Protected by an international patent, this construction has been awarded numerous prizes by the readers and juries of special-interest publications.”
