This Patek Philippe Pocket Watch comes in 18K Yellow Gold Case of diameter 55mm. Features include perpetual calendar, moon phase and minute repeater. Movement : Manual Winding
A repeater is a complication in a mechanical watch that chimes the time on demand by activating a slide-piece. Minute repeaters chime three different sounds; the hours with a low tone, the quarter-hours by a sequence of two tones and the minutes by a high tone
The perpetual calendar shows the right date “perpetually”, coordinating the cycle of long and short months with the leap years. It is a complex mechanism of cams, jumper springs and ratchets that puts a load on the movement. The mechanism distinguishes between months of 30 and 31 days, and leap year.
