Morning Andy.
It's a "shake 'n' go". There is no 'winding' as such. You don't need to worry at all.
Also, I noticed with a new Seiko 5 'Monster' I got which is the same 'shake 'n' go' as yours - that it stops pretty soon (within half a day at most) after you take it off. I don't believe this is anything to worry about either.
Hope this helps.
