I have a SMPO XL (2200.50.00) and I was finally able to locate a gently used OEM rubber strap (98000145) for a decent price but it lacks spring bars. Fom what I've garnered searching the forum, one uses a longer spring bar on the strap than on the bracelet. I was able to find a great deal about the subject on the 42mm SMPO (20mm/19mm) but not on the big boy. I would deduce that it's probably (22mm/21mm) but I'd like a confirmation as well as recommendations or where to purchase replacements. Also, if anyone has a good bead on where to get a replacement tang buckle (O94512022) for the strap, that would be lovely.
This watch is my pride and joy and I definitely do NOT want to mess up something as seemingly trivial as a spring bar and suffer the horrible consequences of it failing.
