Lot Essay

With Patek Philippe Extract from the Archives confirming production of the present watch in 1959 and its subsequent sale on 26 March 1959.
Consigned by an important private collector this watch has never been offered in public before. Obviously seldom used if at all, it is preserved in excellent, original overall condition, showing hardly any surface wear. The case is full and retains its original case proportions to the best extent, reflected by the incredibly sharp edges to lugs and the crisp gold mark. The dial has never been restored or cosmetically enhanced in any way. The hard enamel signature is, consequently, as raised as the connoisseur would expect.

In close to new condition, the present reference 2597 is doubtlessly one of the most attractive examples of this celebrated reference to appear in public in recent years.

Reference 2597
Reference 2597 with calibre 12'''400 HS for heures sautantes or jumping hours was launched in 1958. This highly ingenious system was patented by Patek Philippe in 1959, Swiss Patent 340191 for a "Time Zone Watch". The model was made in two versions, the first, features an independently adjustable hour hand whereas the second, such as the present watch, includes an additional hour hand.

Examples of both versions of reference 2597 are illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, pp. 238 & 239.
