Patek Philippe is for the first time combining the patented Annual Calendar and the Travel Time display system. The technical originality of this Annual Calendar lies in the fact that it always indicates the exact date for local time. In order to provide this original functionality, the engineers have developed a new self-winding movement with a Travel Time mechanism controlling the Annual Calendar and enabling date correction in both forwards and backwards directions.

No less than eight patent requests have been filed for this Caliber 31-260 PS QA LU FUS 24H, relating to elements improving precision, efficiency, reliability, security and user friendliness. This model comes in a new Calatrava-type case rimmed with a Clous de Paris hobnail guilloched pattern. The vintage-style dial is distinguished by its anthracite color and its slightly grainy texture reminiscent of oldtimer cameras. This new reference is teamed with two interchangeable straps: one in beige calfskin with a nubuck finish and the other in black calfskin with an embossed fabric motif and beige topstitching.

A disc, decorated with golden stars and two golden moons against a blue or white background representing the sky, rotates within an aperture. The disc is cut from a wafer of corundum crystal (sapphire).

Gold was condensed onto the disc by means of a vacuum process through a photographic mask to create the shape of the moons and stars.  The aperture is cut at its upper edge in order to represent the lunar cycle.

During the first days of each lunation, the leading edge of a golden moon becomes visible as a crescent on the left of the aperture and appears to wax as it emerges beyond the curved edge of the aperture representing the lunar terminator.

Half way through the lunation, the moon appears full. It then wanes as it disappears behind the terminator on the right of the aperture.

As the moon vanishes, the second moon on the disc is ready to appear on the left.
