A watch that defines what collectors call “museum condition.” This Patek Philippe Ref. 2526, in 18K yellow gold, is triple-signed by Patek Philippe and the legendary Caracas retailer Serpico y Laino — on the dial, caseback, and bracelet. Accompanied by a Patek Philippe Extract from the Archives (31 October 1958), it stands among the finest surviving examples of this historically important reference.
The 2526 is more than a dress watch — it’s Patek’s first automatic wristwatch, powered by the Calibre 12-600 AT, a movement regarded by many as one of the most beautifully finished automatics ever made. The MK2 enamel dial remains untouched, with applied hour markers and flawless surface — a rarity, since most vintage enamel dials show cracks or restorations.
The case retains its original factory geometry, with sharp lugs and crisp bevels that confirm it has never been polished. Completing the piece is its original Gay Frères Type D brick bracelet, signed and dated to the first quarter of 1958 — matching perfectly with the watch’s production date.
For collectors, this example checks every box: originality, provenance, and condition. A true grail for the connoisseur of mid-century Patek Philippe.
