The Rolex GMT Master comes with a black bezel or blue and red bezel, also known as the Rolex ” Pepsi” , and was created with the aviator in mind, in collaboration with Pan-Am Airways. Rubber B has developed a custom Swiss Made Vulcanized Rubber strap for the Rolex GMT which supersedes any competition in the choice field for replacement bracelets or nato style straps for Rolex watches. The open public forum of critique by our previous customers has proved a positive testament to the value and excellence our Rubber B Rolex watchband products have achieved. Rubber B is the absolute best choice when it comes to customizing your Rolex watch, and making it every bit as comfortable and elegant as a Rolex bracelet should be.
