This is a genuine Ronda Caliber 7003 circuit block electronic module, specifically designed for the Ronda 7003 quartz movement. As the core electronic component, it regulates timekeeping precision and ensures reliable operation of the movement.
Ideal for repair professionals and watchmakers, this replacement module offers a practical solution for restoring functionality to Ronda 7003 calibers without replacing the entire movement.
Genuine Ronda Part – Produced by Ronda Switzerland, not a copy or generic component.
Core Electronic Component – Contains quartz oscillator and IC to generate precise stepper motor pulses.
Compatible Movement – Designed specifically for Ronda Caliber 7003 quartz movement (typically three‑hand with date or two‑hand).
Brand New – Unused factory stock, no electronic aging or performance loss.
Cost‑Effective Repair – Replace only the faulty circuit instead of the entire movement.

1. Is this a genuine Ronda circuit block?
Yes. The product is clearly a genuine Ronda part, not a third‑party copy or generic replacement.
2. Which movements is this circuit block compatible with?
It is specifically designed for Ronda Caliber 7003 quartz movements. Different calendar variants may share the same circuit, but verify with your movement‘s parts diagram. Not compatible with 7004, 7005, or other calibers.
3. How can I tell if the circuit block needs replacement?
Symptoms include: fresh battery but movement does not run; no pulse output detected on a timing machine; grossly inaccurate timekeeping; or visible corrosion from moisture damage.
4. What should I pay attention to during installation?
Disconnect the battery first to avoid short circuits. Align the circuit block with the alignment pins and contact pads on the mainplate, ensuring good contact between the metal springs and the coil leads. Inspect the coil for continuity. Use non‑magnetic tweezers and anti‑static precautions. Professional installation is recommended.
5. Does the new circuit need calibration after installation?
The timekeeping accuracy of the Ronda 7003 is determined by the quartz crystal. New factory circuits are pre‑calibrated to standard accuracy (approx. ±15‑20 seconds per month). No user calibration is needed, but it is good practice to check pulse frequency with a timing machine.
