Q1: Is this a genuine ETA part?
A: Yes — this is an ETA 201.001 movement coil block, an original ETA caliber component for the 201.001 quartz movement. It is a genuine ETA part designed to match original factory specifications, not an aftermarket copy.
Q2: What does the coil block do in a quartz movement?
A: The coil block is part of the stepping motor in a quartz movement. It works with the IC (integrated circuit) and magnet to generate a pulsed magnetic field that drives the rotor (stepping motor), which in turn moves the gear train and hands. Without a functioning coil block, the movement cannot operate.
Q3: Which movement uses this coil block?
A: This coil block is designed specifically for the ETA 201.001 quartz movement — an ultra-compact quartz caliber. It is caliber-specific; using it with other ETA quartz movements (e.g., 255.111, 956.112) may not fit. Confirm your movement caliber (201.001) before purchase.
