Patek Philippe’s first automatic wristwatch, the legendary reference 2526 was introduced to the market in 1953. Launched with the celebrated caliber 12'''600 AT, Patek Philippe’s first automatic movement, it is by many considered to be the most beautiful self- winding movement made by any manufacturer.

The reference was produced in yellow gold, pink gold, white gold, and platinum, with all metals fitted with either metal or enamel dials. Those fitted with black dials, like the present lot, are especially rare and sought after. From the first series of dials produced, the dial exhibits beautiful flares around the tops and bottoms of each minute marker. When originally manufactured, the first series dial incorporated holes to secure each baton hour marker – a high cost production method that Patek later abandoned.

With only few examples known, this particular example stands out from the group, having no cracks whatsoever, and with an extract stating the watch was born with a black enamel dial. Another highly unusual feature of this dial is the "SWISS MADE" and "SWISS" designation at the bottom of the dial, which must have been a requirement of local custom authorities where Patek Philippe would ship watches.

It remains in excellent overall condition with strong definition to the case and lugs, and a hallmark present between the lugs. Accompanied by the Extract from the Archives confirming the black dial, this exciting watch can be considered as an ultimate treasure for collectors.

The present watch is one of 18 known yellow gold examples with a black dial.
