Patek Philippe Annual Calendar Regulator 40.5mm 5235G-001 – Silver Dial

Patek Philippe Annual Calendar Regulator 40.5mm 5235G-001 – Silver Dial

A regulator dial separates the hands rather than stacking them: minutes sweep from the centre, hours sit in a subdial at twelve and seconds run at six, a layout borrowed from the precision clocks watchmakers used to set other watches. Patek combines it with the annual calendar, showing day and month in apertures, and drives both from the 31-260 with its Silinvar escape wheel and Spiromax balance spring inside a 40.5mm white gold case.

2017 with original papers; presentation box included. Mint.
