I have an Everest strap , not a Rubber B , but it was $ 230 ish after taxes . OP , I was just like you . I used to think what a ripoff , its just a rubber strap . Why would anyone think this is a good idea ? Then I tried one on , and my opinion did a complete 180 degree turn . The feel isn ' t like any rubber strap you ' ve felt before . Its SO comfortable , fits perfectly , looks like an OEM strap , and honestly an amazing strap . I won ' t be able to convince you that $ 200 for a rubber strap is a good idea or a good buy . The only way you ' ll know is if you try one on . In fact , if you go to a Rolex AD and try on the contentuploads 201503 RolexYachtMastertel 55 E v e r o seGoldCeramicaBlogtoWatch 8 . jpg , that strap feels very similar to the Everest strap I have .
