Patek Philippe Grand Complications 5470

Patek Philippe's Grand Complications 5470P-001 is a chronograph in a 41 mm platinum case. The case measures 13.68 mm thick and is fitted with an interchangeable solid and sapphire crystal caseback, allowing the movement to be viewed. Inside is the manual-winding calibre CH 29-535 PS 1/10, a monopusher chronograph with small seconds and a central hand that reads tenths of a second. The blue varnished dial carries white gold Breguet numerals and luminous hands. A diamond is set at six o'clock on the case. The watch comes on a navy calfskin strap with contrasting hand-stitching, closed by a platinum folding clasp. Patek Philippe rates the case to 30 metres of water resistance.
