In reply to A.C. Ratone.

Although all winders work differently, rotating one full turn every 10 seconds sounds a bit slow. One possible cause for this may be that if the winder has an inexpensive motor, then the weight of the watch could be impacting its rotation speed, resulting in fewer rotations per day than what should occur. Additionally, it is also possible that the motor is starting to give out, and so it is not able to run at its proper capacity.
