Patek Philippe Calatrava 5227

Patek Philippe's Calatrava 5227J-001 is a 39 mm yellow gold watch with a case measuring 9.24 mm thick. The case-middle carries fine curved scalloping through to the lugs, keeping the profile understated. A sapphire crystal covers the ivory lacquered dial, and a sapphire case back sits beneath a dust cover with an invisible hinge, so the self-winding calibre 26-330 S C is visible when the cover is opened. That movement drives a central seconds hand and a date aperture, and it holds a power reserve of 35 hours minimum. The watch is fitted to an alligator leather strap with square scales, closed by a yellow gold prong buckle. Patek Philippe rates the case to 30 metres.
