With my 21j Presidential: Most screws were stripped and would not back out I ended up cutting links with a Dremel to remove them. With an ETA Submariner that came originally from Trusty Time, the screws came out and in with no problem. The quality of the bracelets on Rep Rolexes does seem to be a problem. The $20 watches at Walmart seem to have better bracelets; this is something the Rep Manufactuers need to improve.
