They are not curved end straps but almost have an “end piece” like on Rolex models. And it seems like the spring bars need a very small piler to grip it. My two tools can’t grip the spring bar shoulders at all.
The UN strap system looks very nice. And it fits “OK” on my wrist. But with this larger piece, I want to get an aftermarket curved end strap that allows the strap to actually bend at the spring bar so as to fit my wrist better. But with a curved end so as not to loose the integrated look so much.
