Not completely sure what you are asking, so let me try and cover every possibility
The Breitling bracelet clasps have changed a little in the last few years but the bracelets are unchanged.
There is only one Navitimer bracelet (the one that is 7 pieces wide), although it's available in different sizes and different watches in the Navitimer range require different shaped end links.
You can also fit a number of straps. Breitling produce calf and crocodile leather, both with either tang or deployant clasps, the Diver Pro rubber strap on tang, the Ocean Racer rubber on deployant and the Diver Pro II on either tang or deployant.
Hope the question was answered there somewhere.
