Patek Philippe 5140G Perpetual Calendar Ultra Thin 18K White Gold Silver Dial SEALED

This Patek Philippe Perpetual Calendar reference 5140G-001 carries forward one of the maison's most refined modern calendar lines. Replacing the 3940, it kept the same self-winding ultra-thin caliber 240 Q while enlarging the case, giving the watch a broader, more contemporary stance without disturbing the proportions that made its predecessor so enduring. For a collector drawn to Patek's long run of discreet perpetual calendars, that continuity is exactly the point. Its perpetual calendar is paired with a moonphase display, all driven by the caliber 240 Q, one of the firm's most elegant automatic movements. In 18k white gold, the case measures 37.2mm across and 8.5mm thick, a size that preserves the reference's dress character while giving it more presence than the 3940. The silver dial keeps the watch in the restrained register that suits the model. It stands as the larger successor to one of Patek Philippe's defining perpetual calendars, produced until 2016, before the line moved again with the still bigger 5327.
