百達翡麗，精細及罕有，18K金自動上弦腕表，配乳白色琺瑯錶盤，由Gübelin銷售，型號2526，1954年製

With Patek Philippe Extract from the Archives confirming production of the present watch with raised gold hour markers in 1954 and its subsequent sale on 29 April 1955.

Reference 2526 and its successor 3428 are undisputedly amongst the most elegant and distinguished vintage watches ever made.

Reference 2526 was introduced to the market in 1952 and was Patek Philippe's first self-winding watch ever made, starting with movement number 760'000 (delivered in July 1953 to Mr. J.B. Champion, one of Patek Philippe's faithful clients. This watch, fitted with a gold bracelet, is today the pride of a discerning collector). The model features the legendary calibre 12-600 AT which was granted Swiss patent No. 289758 in 1953 for "a self-winding mechanism for a wristwatch movement using the energy supplied by a rotary mass causing an eccentric part to transmit a swinging movement to an organ of the mechanism".

The majority of reference 2526 was cased in yellow gold, a small series in pink gold and an exceedingly limited number in white gold and in platinum.
