Patek Philippe Reference 2526 A yellow gold wristwatch with black enamel dial, Made in 1955 Dial: black enamel Calibre: cal. 12-600AT automatic, 30 jewels Movement number: 761'510 Case: 18k yellow gold, screw down case back Case number: 687'237 Closure: brown unsigned leather strap and 18k yellow gold Patek Philippe Henri Stern buckle Size: 35 mm diameter Signed: case, dial and movement Accessories: Patek Philippe Extract from the Archives confirming production of the present watch in 1955 and its subsequent sale on 22 September 1955 Patek Philippe introduced their first model featuring the legendary caliber 12'''600 AT self-winding movement, in 1953. The reference 2526 would become an international success and can be found in all precious metals with or without bracelets, and in various dial configurations. The present lot is cased in yellow gold and fitted with a black enamel dial. Enamel dials are, to this day, used sparingly because it is delicate, costly, and difficult to produce –however, Patek chose to use enamel on the reference 2526 for a different reason; it was meant to last forever since enamel dials are not susceptible to the oxidation and moisture damage that can harm the finish of metal dials. Additionally, the dial on the present lot is known as a first series dial, which is distinguishable by the small dimples in the enamel surface that can be seen underneath the top and bottom of each baton hour marker and the long applied baton index at 6 o'clock. These early dials have these dimples since the hour markers are actually set into the dial themselves using pins while all later dials have hour markers glued to the solid enamel surface. Among the plethora of different variations, black dial 2526’s are the most appreciated because of the incredible rarity and unsurpassed appeal of the iconic black dial. 百達翡麗 型號2526 黃金腕錶，備黑色琺琅錶盤，1955年製 附帶後補資料庫精粹
