UOP Swiss Winding Issue

[rarebear]

Hi,
Got my first swiss movement yesterday and was really happy this AM I found it unwound ... Seems if I do not pull on the crown while winding it slips..

I know this can't be a $100 Asian winds eaiser than a $300 Swiss watch..


Whats the problem?
Is there any thing I can do?

Thanks

What movement is it? In what watch? Did you hand-wind it when you got it?

All I know is it is suppose to be a Swiss
I guess it is what comes in the UOP .. I am not sure of model number..

I just checked its a 2824 eta

I felt it slipping last night when I tried to wind it before bed and thought is was fully wound but was dead by this AM when I checked it..

I thought I hand wound it fully but I have to pull on crown while winding or it slips even when watch is unwound..

Is this normal for this movement ?
