·You're right; I had to bend two 19mm springbars slightly to find room for a strap there.
I wholeheartedly recommend using instant glue along with a socket wrench for casebacks. Nearly no chance of scratching anything and residue glue can be cleaned of easily with acetone. This is always how I open my new watches the first time...
The Jaxa is new and I mainly wanted to give it a go. Actually it seems pretty secure and I could get a fair bit of torque on, but I wouldn’t try harder than I did today. So tomorrow I’ll get it on the bench opener assuming I have an adapter that works for the caseback (which actually does look a bit awkward). If no luck with that I’ll have a go with superglue and a big nut.
