The weak link

Interesting question. It's difficult to say that vintage Rolex bracelets stretch more than any other brand. But most people wouldn't want to be walking around with a totally loose bracelet, and if they don't mind, they want to pay accordingly.

I think bracelet condition is usually disclosed because people buying the watch want know they will be able to wear it and it is a common enough question to be asked, that you mine as will include it in your listing if any stretch is present.

Almost any product you buy, that you intend on keeping for multiple years or even decades and beyond will likely experience some "wear and tear." They newer Rolex bracelets are more solid, but if you wear your watches often enough, the bracelet will eventually start to give.

If you clean your bracelet, you can probably reduce the grime that wears away at the metal, hopefully prolonging the life of your bracelet.
