The ETA 2502 is a vintage manual-wind mechanical watch movement produced by ETA SA, a cornerstone of Swiss horology known for reliable ebauches used across brands.
Key Specifications
Size and Beat Rate: 11.5 lignes diameter, 18,000 vibrations per hour (vph) for smooth sweeping seconds.
Power Reserve: Approximately 40-46 hours, typical for ETA 2500-series movements.
Jewels: 17 jewels, reducing friction in critical pivots for longevity.
Functions: Time-only with date complication at 3 o’clock; no quickset date—advance manually between 8-12 o’clock positions.
Design and Features
Crafted in the mid-20th century, the ETA 2502 belongs to the 2500 family, emphasizing simplicity and robustness for dress watches and mid-range chronometers. Its manual winding via a crown ensures direct barrel engagement, delivering consistent torque. The date mechanism uses a simple jumper system, reliable but requiring careful setting to avoid slippage.
Historical Context
Introduced around the 1960s, it powered affordable luxury timepieces from brands like Omega and Longines before automation dominated. NOS (new old stock) units remain available for restorations, often missing minor parts like hour wheels. Collectors value its no-frills construction amid ETA’s shift to higher-beat calibers.
