Need help on Hora Mundi 3700 problem
Bought a pre-owned 3700 world timer. Just got it back from a service in Switzerland via Swatch Toronto.
The watch's minute hand loses 2 minutes a day. The seconds hand runs correctly (-1 second/day). After testing, I have identified the issue, the date change at midnight.
At 10 pm, the watch runs correctly. At 11 pm, it loses a minute. By midnight, it loses 2 minutes. The seconds hand runs correctly. After the date change, the watch runs correctly again.
IN the morning, the watch is still off by 2 minutes, but no more than that.
Everything else works fine, date change and world timer dial.
So, what's happening? Anyone else had this experience?
