PATEK PHILIPPE PERPETUAL CALENDAR POCKET WATCH REF. 725/2J
The ref. 725 was the design inspiration for a long line of Patek Philippe perpetual calendars and perpetual calendar chronographs. It was made in two main series, the first with four subsidiary dials (such as this example) and the second with a triple calendar ‘American-style’ straight line indication.
It is pristinely preserved and offers the collector of pocket watches, or the first-time pocket watch collector the opportunity to own an iconic reference for a fraction of the price of its wristwatch equivalent, the ref. 1518.
Fewer than 100 ref. 725s were made in all configurations and fewer than 21 are known in yellow gold. Five examples of the reference are now part of the Patek Philippe Museum, a testament to the watch’s importance to the Patek Philippe lineage.
