Most of the newer Breitling bracelets are adjusted with fine screws, such as jewelers screws, rather than pins. A question often asked is how do you adjust them? In fact, here is an email that someone sent me a couple of days ago:

“hello…i stumbled upon this site in search of info on the old colt automatic. i just purchased a NOS Colt Auto I (ca. 2005) and was wondering if you can point me out to articles on how to size the fighter bracelet..”

So I figured I would post a Youtube video demostrating how this is done. I accidently went off screen at one point but its still servicable! Hope this helps:
