Here is the case I used that I took the bezel from. I then had to use a dremel and various grit of sand paper to thin the bezel enough where the locking ring would fit and hold the bezel in place (you will end up removing all of the clicking steps and a bit more to make it fit). The original bezel didn’t have a click feature either so it stays true to original functionality. Hope this helps.
