Rolex will not service a watch that has been modded in any way. If an owner simply replaces the bracelet with a different one, Rolex will not service the watch. Their position is the appearance is a fundamental aspect of the product. They did not put the "Rolex" brand on the altered product, so it is a counterfeit product. The altered product is not their design. Rolex has successfully taken legal action against companies selling altered watches with the "Rolex" brand on them, on the basis that they meet the definition of counterfeit. This is not to say it is illegal for an owner or third party to execute any mod they want. CRK may feel the same way as Rolex. That said, I sympathize with the OP. A washer seems like a small thing to ask for.
