If I put a Spring Drive movement close to a mechanical movement, would the mechanical movement get magnetised by the Spring Drive?

In reply to Manan.

Thank you Peter – this helps. It will be interesting to observe this. Maybe Deployany / Grand Seiko should do a short video on this.

If the watch is keeping time during the exposure accurately it’s comparable to a METAS certified Omega. Of course the Omega doesn’t stop. But nonetheless

In reply to Manan. Yes! The hands stop when exposed to a magnetic field of sufficient magnitude. But the watch continues to keep timing. And the watch will automatically advance the hands to the correct time when the field is falls below the threshold.

So the watch is affected by magnetic fields when exposed and later returns to normalcy once the exposure is not there?
