The Complete Calendar Openface 41mm Mens Watch 4020T/000R-B654 showcases the openworked sapphire dial revealing the Calibre 2460 QCL/2 movement, whose main plate and bridges are highlighted by anthracite NAC treatment. The triple calendar display, complemented by a precision moon phase, gains in depth through its functional and contemporary style. The dial is detailed with the complications of the day-date function under the 12 o'clock position, additionally providing the moon phase functionality positioned at 6 o'clock. Presented on a Mississipplensis dark grey alligator leather strap, the 41mm 18ct pink gold case hosts the dial, set beneath sapphire crystal glass for protection. Powered by a self-winding movement, this high precision watch is certified by the Hallmark of Geneva. The timepiece transparent case back and 40 hour power reserve is exquisite in the technical components of this timepiece.
