Patek Philippe at its most technically ambitious, the 5270G-013 is the modern Grand Complication that pairs a perpetual calendar with a true chronograph in one cohesive, column-wheel architecture. Introduced as the Ref. 5270 line in the early 2010s, this white dial variant is associated with a 2013 launch and is prized for its bright, high-contrast dial presence.
Power comes from the in-house manual-winding caliber CH 29-535 PS Q, a movement engineered specifically to drive both the chronograph and the perpetual calendar with long-term stability.
On the dial, the day and month apertures, integrated moon-phase at 6 o'clock, and additional perpetual calendar indications deliver the hallmark Patek Philippe signature layout for this caliber family.
The 41 mm case is crafted in 18K white gold and finished to the exacting standard expected from Patek’s grand complication tier, with a sapphire-crystal display back that reveals the movement’s key components. Unlike many perpetual calendar chronographs, the CH 29-535 PS Q family emphasizes smooth, traditional control with a sophisticated clutch and chronograph drive system.
At 30 meters water resistance, it is clearly positioned as a refined collector’s complication rather than a sports chronograph. In the market, the 5270G-013 remains an especially compelling buy for those seeking a modern Patek perpetual calendar chronograph.
