This is a genuine ETA 2671-705 escape wheel, an original Swiss-made component corresponding to article number 10 for the ETA 2671 automatic movement. As a critical part of the escapement (the regulating organ of the watch), this wheel interacts with the pallet fork and balance wheel to convert rotational energy into precisely divided time intervals.
This brand new original part is essential for watchmakers restoring proper timekeeping when the original wheel becomes worn or damaged.
Genuine ETA Part – Swiss factory-original, perfect fit for Caliber 2671.
Escapement Core – Works with pallet fork and balance to convert gear train energy into stable oscillation.
Precision Machined – Accurate tooth geometry for efficient power transfer.
Essential for Service – Common failure point for inaccurate timekeeping, stoppage, or low amplitude.
Compatible Movement – Designed for ETA 2671 automatic (common in ladies‘ watches).

ETA 2671 automatic movement (common in ladies‘ Tissot, Mido, Longines, Hamilton, etc.)
Repair of severe timekeeping errors, stoppage, or low amplitude not resolved by cleaning and oiling
Replacement of escape wheels with worn teeth, bent pivots, or damaged jewel holes during service
1. Is this a genuine ETA escape wheel?
Yes. It is a Swiss ETA factory-original part (2671-705) for Caliber 2671, not a copy.
2. What are the symptoms of a damaged escape wheel?
Symptoms: very fast or slow timekeeping; stoppage or intermittent running; very low amplitude; irregular ticking noise.
3. What should I pay attention to during installation?
The escape wheel sits between the mainplate and escape bridge. Ensure both pivots drop into jewels and the teeth properly engage the pallet fork. Follow the ETA technical guide. Professional installation is strongly recommended.
4. Does this part fit other calibers like 2671 variants?
Yes, it fits all 2671 variants (e.g., 2671-2). Not for 2892, 2824, or other calibers.
5. Is regulation required after replacement?
Yes. After replacing the escape wheel, check amplitude, beat error, and rate, and adjust as needed. Use a timing machine for final verification.
