How to remove this metal band?

[suby6]

I bought this old Russian manual watch for my girlfriend. After removing all of the removable links it is still too large for her tiny little wrist. If I can get the band off I can dremel off some extra links. Problem is it doesn't seem to be removable unless I am missing something. From the photos can anyone advise if they know how to get it off? One side of the pin/ mount seems to be a small hole, the other us a rounded bump. It doesn't seem to be a screw or normal pin.. Is this a rivet?? One almost looks like it may be a hex shape but they are so small I can barely see. I don't see there being a hex key small enough anyway..

 

If I drill it out where can I get new appropriate pins?

The brand is Chaika (seagull). Only paid $30 for it so not looking to spend a bunch of money on it..

Thanks for any guidance!
