Hah , ok . Sure , I don ' t own an Everest or Rubber B strap but I have tried on the Yachmaster with rubber Rolex calls it Oysterflex from a couple of Rolex boutiques and I also owned briefly an Oris Aquis on rubber , which in my opinion is the best rubber strap on the market . I got the Aquis strap for $ 200 it came with the bracelet and I still think that was overpriced , and it was about onpar with the Oysterflex which comes with a glidelock submarineresque clasp . something I ' ve not seen on any of these aftermarket Rolex straps . You ' re entitled to your opinion obviously , but $ 200 for two 6 inch pieces of rubber and about a quarter ounce of stainless steel is ridiculous from a pure economics standpoint . The only reason these things cost as much as they do is because they ' re for luxury watches plain and simple .
