Patek Philippe Complications 5212

Patek Philippe Complications 5212A-001 has a steel case measuring 40 mm across. The case stands 10.79 mm thick and pairs with a sapphire crystal set into the display back. The self-winding calibre 26-330 S C J SE drives the watch, with a power reserve of 35 hours. This weekday calendar combines day, date, month and central seconds functions on a silvery opaline dial with handwritten-style numerals. A pin buckle in steel closes the light brown calfskin strap. Patek Philippe rates the case to 30 metres of water resistance, modest by sport-watch standards but typical for a dress complication of this kind.
