Patek Philippe Calatrava 4997

The Patek Philippe Calatrava 4997/200G-001 is a women's Calatrava in white gold, its case measuring 35 mm across and 7.4 mm thick. The watch is set with diamonds, adding sparkle alongside the deep blue dial. Inside is the self-winding calibre 240, an ultra-thin movement with a 22K gold mini-rotor and 48 hours of power reserve. A sapphire crystal covers the display back, letting the movement show through. The dial's midnight blue comes from dozens of layers of translucent lacquer applied over an embossed wave pattern. A navy blue calfskin strap closes with a white gold pin buckle to match the case. Water resistance is rated to 30 metres.
