Patek Philippe 5970R Perpetual Calendar Chronograph 18K Rose Gold Silver Dial

This Patek Philippe Perpetual Calendar Chronograph reference 5970R-001 is the rose gold expression of the reference that closed Patek's great line of Lemania-based grand complications. Its manual-wind caliber CH 27-70 Q, based on the Lemania 2310, pairs the chronograph with a perpetual calendar and moonphase in the compact, balanced format that made the 5970 an immediate successor to the 3970 and a different proposition from the larger watches that followed. For a collector who wants that last chapter rather than the modern reset, this is the reference that draws the line cleanly. In 18k rose gold the case measures 40mm across and 12.9mm thick, a size that gives the watch more presence than its predecessor without disturbing its dress proportions. The silver dial keeps the display unusually legible for so information-dense a watch. Few Patek references tie classical complication, transitional significance, and such resolved proportions together quite this neatly. This particular example has been in the safe for over 10 years, making it an outstanding collector example.
