OEM watch builds or aftermarket replacement
1. Is this a genuine ETA movement?
Yes. It is a Swiss ETA factory-original caliber 955.432, not a copy or refurbished unit.
2. Does the movement include a battery?
No. A battery must be purchased separately. Use a high‑capacity 55.0 mAh battery to achieve the stated 188‑month lifetime.
3. Does the movement have a seconds hand?
This movement is hours/minutes only – no seconds hand. The stop motor technology exists but has no visible effect.
4. How do I install it?
Install hour and minute hands, and cut the winding stem to the correct length. Professional watchmaker installation is recommended.
5. Is the theoretical 188‑month battery life realistic?
Theoretical value under optimal conditions (recommended battery, moderate temperature, infrequent setting). Actual life may be slightly shorter, but still far exceeds typical quartz movements.
