SS Oyster Braclet wear/tear question:

[Kris]

When purchased brand new, how long does it generally take for one to see signs of stretching/warping of the pin in the links of a 904L SS Oyster braclet?

I'm assuming it isn't the links that are stretching, but rather the pins/screws that hold the links together that are bending under wear-stress.

Which would promote faster braclet stretching, a braclet that is tighter around the wrist or one that has more slack?

Has anyone here ever heard of a Rolex SS oyster braclet snapping from ordinary (general day-to-day) wear or is the worst that usually happens is that the braclet is just stretched out and warped to the point where it's ugly and a new braclet is in order?
