This is a genuine MIYOTA coil block (Part No. 246-137) for 5R21 and 5R32 movements, made in Japan, designed for ultra-small quartz calibers. It serves as the core drive component of the stepper motor, converting electrical pulses from the circuit board into magnetic force to drive the gear train. The 5R21 is a two-hand movement while the 5R32 is a three-hand movement—both are ultra-small calibers specifically designed for ladies’ watches. This product is brand new and original, intended for repairing movements that fail due to open circuits, short circuits, or corrosion damage to the coil.
