Grand Complications Platinum Celestial Watch ref. 6102P-001 6102P-001

The Celestial is distinguished by its mobile sky chart reproducing the visible movement of the stars, as well as the position and phases of the Moon. An ellipse placed on the underside of the watch crystal defines the sky opening as visible above Geneva and all cities on the same latitude. The date is displayed by a central hand moving over the dial circumference.
