This automatic caliber 315 movement is rhodium-plated with fausses côtes decoration and the stamp of the Seal of Geneva quality mark. It is constructed with 316 parts and contains a straight-line lever escapement, a shock absorber mechanism, and a 21K gold rotor. The mechanism oscillates at 21,600 vph (3Hz). It has a self-compensating, free-sprung balance spring and a patented Patek Gyromax balance spring that compensates for cold, heat, isochronism, and five positions.
Three correction push-pieces to adjust the calendar indications:
Month correction at 2 o'clock, date correction at 4 o'clock, and day of week correction at 10 o'clock . The dial, case, and movement are all signed.

This Annual Calendar mechanism distinguishes between months of 30 and 31 days. The ingenious mechanism is entirely rotary, without the uneven movements of cams and springs in the conventional perpetual calendar.

Patek Philippe produced this model from 1996 to 2005 and was named "Watch of the Year" in 1996; the watch was a phenomenal success in Switzerland. In addition to its aesthetic and technical qualities, the Annual Calendar featured a complication deemed "useful," simple to operate, and brand new to the watchmaking industry.

Warranties & Repairs

At Twain Time, trust is our timepiece's best friend. Our commitment to quality spans every pre-owned watch and mechanical marvel in our collection. Should the unexpected occur, count on us to swiftly make things right. We treasure our clients' satisfaction and trust above all else—this ethos echoes through every member of our team.

Each pre-owned watch undergoes meticulous, non-invasive mechanical scrutiny and servicing if needed. This ensures they not only meet but exceed our stringent standards for accuracy and functionality.

Rest easy knowing that unless otherwise noted, our pre-owned watches come with a robust warranty—either full or limited—spanning twelve months. However, this doesn't cover damages from misuse or accidents. Given their age, some watches may require gentler treatment than when they were brand new.

For those watches serviced by their original manufacturers, they bear the manufacturer's guarantee, surpassing our standard warranty.
