Patek Philippe 2526 ivory, black or breguet dial

The Patek Philippe Reference 2526 is notable as the brand's first serially produced automatic wristwatch. Introduced in 1953, it marked a significant technical advancement for Patek Philippe, housing a self-winding movement at a time when manual-wind mechanisms were still prevalent. This reference is recognized for its clean aesthetic and robust construction, establishing a foundation for future automatic timepieces from the manufacture. The watch features a 35 mm case, available in 18k yellow gold, 18k rose gold, or platinum. It is powered by the caliber 12-600 AT, an automatic movement with a Gyromax balance and a solid gold rotor, offering a power reserve of approximately 40 hours. The crystal is acrylic, protecting a silver dial that often features enamel. The case design is characterized by its smooth bezel and often includes a screw-down case back, contributing to its water resistance. For collectors, the Reference 2526 is highly sought after due to its historical significance as Patek Philippe's inaugural automatic model. Variants exist with different dial configurations, including those with applied indexes and small seconds, which can vary between the gold and platinum versions. The presence of original bracelets, particularly on rose gold models, can also add to its collectibility, as these were less common than leather strap configurations.
