·As I mentioned in the other thread, strap size is reference specific, not just based on case size. I believe a 12296 takes a 20mm strap. However it also depends on the brand somewhat as there are variations in accuracy of the actual strap size. So if you google this ref you will see 18mm, 19mm, and 20mm straps being used.
