    The difference in dial diameter between the 5A Japanese movement and the genuine product is 0.5 to 1mm
    The diameter of the dial of the 10A Swiss movement differs from that of the genuine product by 0.2 to 0.5mm

  • Multi-functional meter calibration and detection

    Daily deviation reference, amplitude reference, polarization reference
    Japanese movement ±10-15s/d 240°-300° ≤ 0.6ms
    Swiss movement ±5-10s/d, 270°-320°, ≤ 0.3ms
