Patek Philippe Grand Complications 5270

Patek Philippe Grand Complications 5270P-015 is a chronograph in a 41 mm platinum case. The case measures 12.4 mm thick and carries two-tier lugs with a fully polished finish. A diamond is set at six o'clock on the case. The dial sits under a sapphire crystal, and the caseback is also sapphire, showing the movement within. Inside is the manual-winding calibre CH 29-535 PS Q, combining a chronograph with a perpetual calendar that tracks day, month, leap year and moon phase alongside small seconds and a tachymeter scale. The watch is fitted to a black composite strap, closed by a platinum folding clasp rated along with the case to 30 metres of water resistance.
