Not often one runs into the legendary Patek Philippe ref. 2526 and even less often, you run into a reference 2526 with a dial signed for Swiss retailer Gübelin —one of the oldest retailers in Switzerland founded in 1854. The Patek Philippe ref. 2526 was the first automatic wristwatch launched by Patek and introduced to the market in 1953. Fitted with the Patek Philippe 30-jewel automatic calibre 12-600 AT —Patek's first automatic movement— it is by many considered to be the most beautiful automatic movement made by any watch company and one that remains hidden under the solid case back of the reference 2526.
