This is a wonderful example of 18k yellow gold Patek Philippe ref. 2526 retailed by Serpico y Laino. The rarity of the present specimen is enhanced not only by its outstanding condition but also by the signature of the retailer Serpico y Laino – Patek Philippe’s agent in Caracas – signed on the enamel dial and the initials “S.&L.” stamped on the case back.
The "type D" guilloché brique-form original gold bracelet was manufactured by Gay Frères (founded in 1835 in Geneva) with “GF” initials stamped on the buckle.
The push/pull 18K yellow gold crown is  adorned with sculpted opposing 'Ps', which makes it very distinctive. Patek used this style of crown for only a short period of time and then discontinued it.
The ref. 2526 is really just one model among a handful that used Patek Philippe's very first self-winding caliber – 12-600 AT – though many refer to the 2526 as being Patek's first automatic.
This reference can be divided in three distinct series:
- First series: domed case back, enamel dial and riveted indexes. The dial presents flared holes under each index to allow for their setting.
- Second series: domed case back, enamel dials with the numerals glued to the surface. The dial presents only two flared holes for the hands.
- Third series: flat case back, and in later examples metal dial.
It was then replaced in 1960 by the model ref. 3428 (the so called fourth series), equipped with the second generation self-winding movement, calibre 27-460.
