Pandora Type Euro Style Watch Band

I was eager to get this to make a Christmas Bracelet watch in this style. I had several nice beads for it. As you know they add up. When I made up the watch,I was unhappy,It looked great but the beads fall off when it is opened.

I am new to working with this style but the unscrewing ends for me on this did not work, Maybe you can make it work better,or know how to add a safety catch, I am sick of it so when the other comes will probably put it up . I am sticking with my old way and will just make the Euro bracelets instead I hate losing but it is not the first time my skills and desire did not match up.At least maybe someone can make it better...

There are three pieces.The attachment to the watch is the claw type,Each end has a screw type end Ends fit in the one piece fold over clasp.

The beads pictured and the watch pictured are not included they are soon to have a new life here..
Yo offset my loss will just be mailing it in an envelope.Will post it the day after paid.

Thanks for looking
