PAM with A7750 runs OK on wrist but stops in winder

[Valmor]

Received recently - PAM 1499 with inverted A7750. All looks OK when I wear it, running smooth, rotor movement seem fine at a glance. But when I leave it in winder - it stops after some time. Winder OK, no issues with other watched including a7753 Chopard. Tried all settings - CW(recommended), CCW, Bi-Dir, all rpms up to 1000 - still stops. Any ideas how it happens? Should I worry or nothing to bother?

Have you tried fully winding it at the beginning of the day?. How long is the power reserve off of the winder?

I winded it 3 days ago, wear for 10-12 hours/day and it running OK since that with no rewind. Don't think that clone 7750 can go that long with no automatic winding.

The 7750 should have 35+ hours of reserve when fully wound (mine see over 40). You should be able to set it down and the next morning it's still running and accurate.
