Watch winder's

[Gingerbread Man]

My girlfriend wants to buy me one for my birthday. I'm all up for it, or I was, but upon reading reviews it seems that they don't last long until a motor gives out.

Is this a simple repair, something that seemingly has to be done every other year??

Recommendations for a good one if possible.

Also, I don't wear my watches daily. If the watches are running 24/7, is that a downside to my current usage?

I will often go without wearing a watch for over a week if I don't go out. I have a few watches that could sit in it, so some will go in wore for a while, while others are chosen.

I get the more wear argument if running 24/7, but is that better than lack of use?
