Finally found a reasonably priced JB Champion in great condition. Problem is, I can't seem to tighten it with one hand. Any tips or tricks out there? Mine seems to get stuck as you try to shorten it at the folding clasp.
I'm not sure of the exact nature of the problem you are describing but here are a few pictures I've shared before to help others get the feel for how the bracelet works and how to tighten it and secure it on your wrist.
You should PERMANENTLY adjust the length first. Then the bracelet is ready for wear and can be easily locked on with one hand.
