ETA SA 1260

The ETA caliber 1260 is a Swiss movement manufactured by ETA SA, produced during the 1950s and 1960s. It features 15 or 17 jewels with Incabloc shock protection, though some executions shipped without it. The movement can be identified by the "1260" stamp located under the balance wheel. It was used in Pontiac Nageur watches and vintage Tudor timepieces. Production has been discontinued.
