Just acquired this watch with claim it had been recently serviced (yes, I know) and it’s running incredibly fast. Second hand makes it around in 48 seconds. Timed over an hour and it gained 12-13 minutes. That’s fast! It’s in beautiful condition so may decide to keep it. Any guess at what’s going on? Is it conceivable that something happened in shipment to cause that? I’ve never had a working watch that ran so fast. Thank you.
