I have a Limes Thousend. It has no straps or pins because- well I don't even remember why. I think they got lost moving. Anyway, it's not just a normal spring double flange type deal. It goes in through one end and screws into the other end of the watch case. It's one piece- it's not ones where you have mini screws at each end or anything. I can't seem to find any. I'm sure it's simple, but I'm a little lost. Thanks!
