PATEK PHILIPPE, REF. 5140J-001, A FINE 18K YELLOW GOLD PERPETUAL CALENDAR WRISTWATCH WITH MOON PHASES AND 24 HOUR INDICATOR

Initially introduced in white gold in 2006, Patek Philippe Reference 5140 replaced the 32 year reign of the beloved Reference 3940. A year later, such as the present lot, Reference 5140 was produced in yellow gold. Thanks to the impressive Patek Philippe inhouse Caliber 240Q, which is also found in Ref. 3940, a perpetual calendar, moon phases, leap year, and 24 hour indicator are all able to fit into a compact 37mm case while maintaining an impressive thickness of only 9mm.

It takes an exceptional amount of fine watchmaking to achieve such as feat, proving Patek Phillipe as a superior manufacturer. Caliber 240Q is able to achieve automatic self-winding while maintaining slimness through the utilization of a microrotor. The 22k yellow gold microrotor acts as a double edge sword by allowing the viewer to fully appreciate the Côtes de Genève, Anglage, and Perlage finishing techniques while maintaining automatic self-winding capabilities. The present lot, Reference 5140J is an exceptional contemporary wristwatch that will remain a timeless classic with rich DNA an history.
