Rolex

Original condition never polished or refurbished.

In order to extend the life wear of older Rolex bracelets when they become loose it is common practice  to have them refurbished / tightened (replacement of  of tubes and pins in the bracelet).   When refurbishment is done outside of Rolex, the replaced tubes/pins are  non Rolex parts.   Rolex will refuse to service or accept the watch for repairs in their Rolex Service Centers when refurbished outside of Rolex.
