Rolex keeps very tight control over the supply of its watch components (bracelets included), so only Rolex will be able to supply you with a replacement clasp/bracelet. With that in mind, Rolex will also only sell you one if your watch was originally designed to have one (for example, Rolex will not sell a Glidelock clasp to an owner of a Submariner from the previous generation who just wants to upgrade their bracelet). All of that being said, it is not impossible to find bracelet components on the secondary market, so you may have some luck sourcing one through the various forums.
