This is a genuine circuit block electronic module for the MIYOTA/CITIZEN 0S80 quartz movement, designed for the 0S80 series two‑hand (hour, minute) minimalist quartz calibers. The module integrates a quartz oscillator and CMOS integrated circuit, generating a precise 32,768 Hz time base frequency to drive the stepper motor for accurate hour and minute hand movement. As an original OEM replacement part, it provides a direct solution for repairing movement failures caused by water ingress, battery leakage, or aging electronic components.
Genuine MIYOTA Part – Japanese factory‑original for 0S80, not a copy, ensuring perfect fit.
High-Precision Time Base – Integrated 32,768 Hz quartz oscillator provides a stable and reliable time reference.
Two‑Hand Minimalist Design – Drives only hour and minute hands, ideal for ultra‑thin or minimalist watches.
Low‑Power CMOS Circuit – With an SR626SW (377) battery, it delivers a typical battery life of 3‑5 years.
Cost‑Effective Repair – Replaces only the faulty circuit board instead of the entire movement, offering significant cost savings.

MIYOTA/CITIZEN 0S80 quartz movement (common in ultra‑thin ladies‘ watches, minimalist fashion watches, and some two‑hand models from brands like Casio, Seiko).
Repair of non‑running movements, inaccurate timekeeping, or no response after battery replacement.
Particularly suitable for failures caused by water ingress, battery leakage corroding the PCB, or aged electronic components.
Professional watch workshops, DIY enthusiasts.
1. Is this a genuine MIYOTA circuit board?
Yes. It is a Japanese factory-original part for the 0S80 movement, not a third-party copy.
2. How can I tell if the circuit board needs replacement?
Symptoms: the movement does not run with a fresh battery; no pulse output detected on a timing machine; visible corrosion on the PCB due to moisture or battery leakage.
3. Is this module compatible with other two‑hand movements like 0S90?
Not necessarily. The PCB dimensions and contact layout may differ between 0S80 and 0S90. Verify the original circuit board shape. Use only for 0S80 movements.
4. Does the new circuit need calibration after installation?
No. Timekeeping accuracy is determined by the quartz crystal. New factory circuits are pre-calibrated to standard accuracy. A timing machine check is optional but recommended.
5. What should I pay attention to during installation?
Disconnect the battery before handling. Align the circuit block with the locating pins and contact pads on the mainplate, ensuring good contact between the metal springs and the coil leads. Use non-magnetic tweezers and anti-static precautions. Professional installation is recommended.
