The ETA 2512-1 is a compact manual-wind mechanical movement from ETA, ideal for ladies’ watches during the quartz era transition.
Overview
Developed in the late 1970s, the ETA 2512-1 exemplifies efficient Swiss engineering for smaller cases. Produced roughly from 1976 to 1983, it prioritizes reliability with a bare finish and modern construction borrowed from movements like the ETA 2410. Its 7 3/4”’ diameter (about 17.2mm) and 2.85mm height suit slim designs without a seconds hand.
