Breitling do calf and crocodile leather with tang or deployant in a number of colours as well as the Diver Pro II and Ocean Racer rubber straps. DP II is available on tang or deployant, OR is only on deployant. You may also be able to find a discontinued Siver Pro rubber on tang. Finally there is a metal bracelet option, the Pro II.
