Breitling spring bars

[van_damme1988]

Hi guys.

 

I am thinking of buying gen strap for my Superocean 42 and those spring bars comming from rep factory do not look very trustable, so the question is where/which should I buy? I know that I am looking for 20 mm spring bars  but I would like to buy those, which are gen or at least close to gen. I have done some reading and found this picture (from what i remember from that post is, that those on the left should be from SO42 and navitimer on the right):

 

 

I have done a little search and found these:

The only thing I am not sure is the diameter. Will these 1,78 mm fit rep lug holes and gen breitling 428x strap?

 

Thanks a lot for any answers
