Lot Essay

Accompanied by Patek Philippe Extract from the Archives confirming production of the present watch in 1868 and its subsequent sale on 7 October 1870.

This watch is one of the earliest perpetual calendar watches made by Patek Philippe. Whereas the aperture for the phases of the moon is normally showing "upwards", the present layout is rather "hanging". No other watch by Patek Philippe is known with such a display, supporting the idea that at the time of its manufacture the perpetual calendar mechanism was still in its infancy.
