This is a genuine MIYOTA coil block (Part No. 246-112/246-119) for the 1M02 movement, made in Japan, designed for the 1M02 quartz caliber. 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 for accurate timekeeping. The 1M02 is a 10½ ligne 3-hand day-date movement (hour/minute/second, day/date at 3 o’clock) commonly found in various quartz 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.
