According to the Breitling website the size of the interhorn width is 24/20 for the Navitimer World. It may be a dumb question but what does the 20 represent? I've seen some nice straps on Strap Culture that I'm interested in that say 24/24. Does this mean that I can use them because of the first number 24? If yes does that mean anything 24 will fit without restrictions? Sorry if this is a double post but i tried search and I couldn't find anything. Thanks for the help!!
