Watch winder question

[Skywalker]

I have a few watches with swiss and asian 7750 movements in them...the only watch winder I have is a bidirectional winder with my rolex on it (needs to be bidirectional).

Is there any harm in putting the 7550 watches in the bidirectional winder? Or is the only issue that they might not become fully wound?

My winder can be set to either bidirectional or a single direction. When set to bidirectional the 7750 would always die on the winder. Maybe if you doubled the wind speed it would work, not sure because I just set mine to single direction

.....and make sure when wearing your 7750 to only move your wrist in one direction
