I have a real nice rivet bracelet that came on a rep I bought. Ive never had a yuki to compare it with, but I have many rep rivet's and this is the only one with genuine construction like the yuki has.
I made the mistake of trying to open the holes to accept 2mm bars. I used a tiny punch and just slowly forced it through. I got the bars in, and when I installed it on a watch, the endlink fit is all wrong. The endllinks fit perfect before I did this I sent it along with some other work to Jmb and he manipulated them and got them better, but they are still off. Such a dissapointment! This is a really nice bracelet too. It's a stretch fit with spings that my jeweler had resized for me the correct way with pins too.
I implore you to not do what I did, you might be lucky but you'd be better off sending it to Jmb or someone to drill out.
