Winding the GMT II, Perhaps Too Much?

[finance21]

I have been giving the GMT some rest lately, switching time between a few other watches periodically during the week. I do not own a watch winder, so of course I end up having to wind the Rolex GMT II perhaps once maybe twice per week. Now, I am sure this has been discussed however, could not find anything on this topic.
Does anyone know if I can wind the watch once, twice per week (assuming it runs out of juice) without causing damage to the watch? My guess is that it is O.K. since the movement is robust however, your thoughts are appreciated.
