The discovery of a previously unknown highly complicated watch by Patek Philippe is always eagerly awaited and incredibly exciting, all the more so when it is an almost certainly unique piece. As is the case with the present exceptional horological Patek Philippe masterwork, no other examples are known to exist. This watch has evidently been carefully preserved and has survived in almost untouched condition for nearly 120 years. This, combined with the very large and heavy 60 mm pink gold case, perfect 24-hour dial and movement with a unique repeating mechanism and combination of complications, make it a very special watch indeed. Additionally and quite incredibly, the original Certificate of Origin and sales receipt has remained with the watch. This watch is very likely one of the most important newly discovered 19th-century Patek Philippe watches of recent years.

The movement: Patek Philippe No. 97443 has the following complications:
–
24 hour train the hour hand making one full revolution once in 24 hours This requires a completely specially constructed movement with wheels of a higher tooth count so that the hour wheel revolves at half the speed of a standard 12-hour watch. In consequence, therefore, the dial is numbered with the hours from 1 / 24 to allow for this.
–
Full 24 hour repeating The unique feature of watch No. 97443. When the repeating slide is activated, the hours are struck in full from 1 o’clock right up to 24 strikes for a time between midnight and 1 am.
–
Quarter repeating After the hours are struck, if the time is after 15 minutes past the hour, there is a further double strike for each elapsed quarter-hour, up to three double strikes after 45 minutes past the hour.
–
Special type five minute repeating Watch No. 97443 has in addition to the full 24-hour and quarter repeating an unusual type of five minute repeating. The usual manner of striking for a five-minute repeater is a strike for each elapsed hour and then a further single strike for each elapsed five minutes thereafter. However, in the present watch, after the 24 hours and quarters have been struck, up to a further two single strikes are sounded for each fi ve minutes after each quarter and every ten minutes after each quarter.
–
Chronograph With safety locking bolt on the case and co axial button in the crown for all three operations. Without leap-year indication on the dial. The calendar mechanism of this watch makes an automatic correction for the lengths of the days in the month and leap years.
–
Moon phases Indicate the waxing and waning of the moon during its 29½ day cycle. The indication scale for the moon’s age is on the periphery of the aperture.
