Lot Essay

The present watch represents the state of the art in watch manufacturing from the heydays of complicated and ultra complicated timepieces. Uniting two of the main complications established at that time, being the perpetual calendar for the astronomical functions and the distinct minute repeating for the acoustic pleasure, it is furthermore enhanced by one of the best degree movements available at Patek Philippe and a high quality case.

The dial consists of seven parts and features the most desirable Breguet numerals and hands, the case is very high grade with a hidden hinge, becoming almost invisible following the curve of the case when the cover is closed. Naturally the movement incorporates all the characteristics the collector expects to find in a complicated timepiece made by Patek Philippe: wolf’s tooth winding wheels, calibrated escapement, swan-neck micrometer regulator, furthermore adjusted to five positions including heat, cold and isochronism.

Patek Philippe’s earliest known minute repeating perpetual calendar watch was made in 1874, no. 47’572. To date, only some 85 watches with these complications are known from the market or from publications, out of which around 60 were made before WW2, rendering them exceedingly rare.

A similar watch, no. 197’875, is illustrated in Patek Philippe Museum - Patek Philippe Watches, Volume I, p. 383.
