Lot 229

Patek Philippe Genève, Movement No. 733071, Case No. 2625847, Ref. 2509, Cal. 27-AM 400, 35 mm, circa 1964
A very fine, elegant Geneva wristwatch with auxiliary seconds - "Large Calatrava"
Case: 18k gold, screw back, movement protection cap. Dial: silvered. Movm.: bridge movement, Geneva quality hallmark, Gyromax balance.
Reference 2509 was produced from 1950 to 1967. The large Calatrava has a slightly larger case than the classic model and and an unusually screwed back. The cases were made by Taubert & Fils in Geneva (initialed FB in the back), the leading supplier of water-resistant cases who delivered to Patek Philippe as well as to Vacheron Constantin.
A striking detail is the luminous dial - the luminous mass of indexes and hands is Tritium, which is unusual for this reference.
