This is a genuine Ronda Caliber 1009 quartz movement circuit block, also compatible with Ronda 1006 movements. The module integrates a quartz oscillator and CMOS integrated circuit, generating a precise 32,768 Hz time base frequency to drive a stepper motor for accurate hour, minute, seconds, and calendar functions. As an original factory replacement part, it quickly repairs movement failures caused by water ingress, battery leakage, or aging electronic components without replacing the entire movement.
Genuine Ronda Part – Swiss factory‑original for Caliber 1009/1006, not a copy.
Integrated Quartz Oscillator – Provides a high‑accuracy 32,768 Hz time base.
Multi‑Function Support – Drives hour, minute, seconds hands and calendar (date/day, depending on version).
Low‑Power CMOS Circuit – Delivers ultra‑long battery life (typically 5‑8 years) with the appropriate battery.
Cost‑Effective Repair – Replaces only the faulty circuit board, far cheaper than a whole movement.

Ronda Caliber 1009 and 1006 quartz movements (common in mid‑range Swiss and Asian brand three‑hand watches, e.g., some Tissot, Certina, Swatch models).
Repair of non‑running movements, inaccurate timekeeping, abnormal calendar function, 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, brand service centers.
1. Is this a genuine Ronda circuit board?
Yes. It is a Swiss factory‑original part for Caliber 1009/1006, not a copy.
2. Are the circuit boards for 1009 and 1006 movements interchangeable?
Yes. Ronda 1009 and 1006 share the same circuit block and are directly interchangeable.
3. How can I tell if the circuit block needs replacement?
Symptoms: the movement does not run with a fresh battery; no pulse output detected on a timing machine; calendar does not advance (non‑mechanical fault); visible corrosion on the PCB due to moisture or battery leakage.
