The ETA 2837 is a reliable automatic mechanical watch movement from ETA SA Manufacture Horlogère Suisse, part of the Swatch Group. Produced briefly in the mid-1970s, it powers vintage Swiss watches with day-date complications, known for its precision and quick-set features.
Key Specifications
Size and Build: 11.5 lignes (25.60mm diameter, 5.10mm height); 17 jewels.
Frequency: 36,000 beats per hour (5Hz) for smooth sweep seconds; 40-hour power reserve.
Functions: Hours, minutes, sweep seconds; quickset day (2 languages) and date.
Features and Performance
The movement includes a hacking seconds hand for accurate time-setting and belongs to the ETA 2800 family, evolving from manual-wind models like the 2821. Its high beat rate enhances timing stability, ideal for chronometer-grade watches like the Mido Commander. Robust construction ensures durability under daily wear, with easy servicing using standard ETA parts.
Historical Context
Introduced around 1974-1975, the 2837 targeted mid-range automatics amid the quartz crisis. Variants include the slower 28,800 bph 2836; it’s less common today but prized by collectors for vintage restorations. Spare parts remain available from suppliers, supporting ongoing repairs.
