I have a Seiko 5 "Military" w/ a 7S26 movement (I think),
And a Seiko 5 Sport "Military" w/ a 7S36B movement.
My average day, is wearing either watch for 8 hours of work (which includes a good amount of moving around and using my hands) plus 4-6 more hours at home (which can be busy, working in the garage or what not).
If I take my watch(s) off say at 8pm, by 8 or 9am the next day, they are unwound. Is that normal?
