Just received my 7206 bracelet that I sent to CWR (Michael Young @ Classic Watch Repair) in HK. His little shop of elves do a great job. When I bought this bracelet a year ago, it had some reasonable stretch in it. Not ridiculous, but stretched nonetheless. Now it's practically NOS.
If you have a vintage bracelet that you're thinking of sending him, depending on the stretch, the finished product can be about 1 link shorter. He can add a link for you at additional cost.
I ve dealt with MY several times and his bracelet repair is excellent and well worth the $200.
I will be sending him my 6636 next.
