From enthusiasts to collectors alike, all eyes were captured at Baselworld 2011 with the introduction of Patek Philippe Reference 5270. The timepiece marked the latest iteration from the legendary Patek Philippe Perpetual Calendar Chronograph family that began with Reference 1518 in 1941.

Reference 5270 differentiates itself from its predecessor (Ref. 5970) by increasing the case diameter to 41mm while decreasing the case thickness by 1mm. Achieved through in-house caliber CH 29-535 PS Q, an additional feature of a day/night indicator further pushes the movement as an impressive feat of engineering. The subsidiary registers are also playfully lowered just below the central axis.

The present lot, Reference 5270P-001 is crafted from platinum with a matching platinum deployant clasp. Like all timepiece crafted in the most noble metal from Patek Philippe, a diamond is subtly placed between the lower lugs. The lovely salmon dial helps drive the vintage aesthetic of the complicated timepiece, in additional to the white gold leaf hands. A sapphire case back allows for one to fully appreciate the hand finished Côtes de Genève and anglage beveling of the manual-winding movement.
