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.
