Serial: 681063 / Mvt 723500
Circa: 1954
Reference: 2509J

CASE: 35mm, 18K yellow gold, screw back

DIAL: Champagne dial with yellow gold applied hour markers, subsidiary seconds at 6 o'clock

MOVEMENT: Calibre 12-400, manual wind, 18 jewels

CONDITION REPORT: The dial is original and untouched and retains an even and rich champagne color. The transparent coating (zappon) has slight crazing, which is not visible to the naked eye, but shows it to be present and original. The case appears to have been polished in the past, but is still thick and very attractive.

NOTES: Comes with Archives extract confirming production in 1954. In production between 1950 and the late 1960s, reference 2509 is the twin of its contemporary reference 2508. The difference among the two models is that the 2508 has sweep centre seconds, while the 2509 features subsidiary seconds. The current example features strong hallmarks, a well-preserved dial, and of course its original soft iron dust cap. Introduced during a period when Patek Philippe emphasized both elegance and technical resilience, the reference 2509 was notable for its robust waterproof case, manufactured by Taubert & Fils, a respected case maker known for its screw-back designs. This added durability, combined with the anti-magnetic properties provided by the soft iron inner cap, made the 2509 a rare blend of understated aesthetics and practical engineering.
