I bought a totally new watch, as far as I know you can't add the diamond bezel alone. About 2 months after that I bought the black with diamond bezel and diamond center. A month after that I got my X the black with diamond markers, and then after that I got a good friend of mine the white with diamond markers. Everyone who has seen this watch and who I've given them to has LOVED them. So congrats on owning such a lovely timepiece
Now if only I could get my bf to fall in love with the diamond bezel chrono
