## Product Description
This is a genuine Ronda Caliber 6004 quartz movement circuit block, the core electronic control unit of the movement. The module integrates a quartz oscillator and CMOS integrated circuit, generating a precise 32,768 Hz time base frequency, which is divided to drive a stepper motor for accurate hour, minute, and seconds hand movement. 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.
## Key Features & Function
- **Genuine Ronda Part** – Swiss factory‑original for Caliber 6004, not a copy.
- **Integrated Quartz Oscillator** – Provides a high‑accuracy 32,768 Hz time base.
- **Low‑Power CMOS Circuit** – Delivers ultra‑long battery life (typically 5‑8 years) with the appropriate battery.
- **Direct Stepper Motor Drive** – Outputs stable pulses for precise second‑hand stepping and hand motion.
- **Cost‑Effective Repair** – Replaces only the faulty circuit board, far cheaper than a whole movement.

## Applications
- Ronda Caliber 6004 quartz movement (common in entry‑level three‑hand watches from Tissot, Certina, Hamilton, etc.).
- 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, brand service centers.
## Frequently Asked Questions
**1. Is this a genuine Ronda circuit board?**
Yes. It is a Swiss factory‑original part for Caliber 6004, not a copy.
**2. 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; visible corrosion on the PCB due to moisture or battery leakage.
**3. What should I pay attention to during installation?**
Disconnect the battery first. Align the circuit block with the locating pins and contact pads, ensuring good contact between the metal springs and coil leads. Use non‑magnetic tweezers and anti‑static precautions. Professional installation is recommended.
**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. Is this module compatible with all Ronda 6004 variants (with or without date)?**
The Ronda 6004 family typically uses the same circuit board; the date function is mechanical and not driven by the electronics. Thus, the module is universal. However, verify the original PCB shape.
