The ETA 1260 is a vintage manual-wind mechanical movement produced by ETA in Switzerland during the 1950s and 1960s. Known for its reliability in dress watches, it features a compact design with sub-seconds at 6 o’clock.
Key Specifications
Size and Height: 10.5-11.5 lignes diameter, approximately 3.95 mm thick, making it slim for elegant cases.
Functions: Hours, minutes, and small seconds subdial; manual winding only, no automatic rotor.
Jewels: Typically 17-18 jewels for reduced friction and longevity.
Frequency: Standard 18,000 vph (2.5 Hz), with power reserve around 40-45 hours.
Historical Context
Introduced post-WWII, the ETA 1260 powered affordable luxury watches from brands like Pontiac, including the Pontiac Nageur diver and gold-plated dress models. Variants like Cal. 1280 and 1281 expanded the family with minor tweaks for specific applications. Its simple architecture made it ideal for servicing, though modern repairs may require donor parts due to rarity.
Usage and Legacy
Common in 1950s Pontiacs and other mid-tier Swiss brands, the 1260 exemplifies ETA’s early dominance in workhorse calibers. Collectors value it for vintage restorations, but performance issues post-servicing—like balance jewel problems—highlight the need for skilled watchmakers. Today, it’s a favorite among horology enthusiasts for its clean aesthetics and historical charm.
