My good friend and R-L-X.de owner Hannes helped me purchase a custom sapphire caseback for my Daytona this summer. Ever since seeing photos of his Zenith Daytona with a sapphire caseback, I've wanted one. When I got my new Daytona in April, and knew I had a Parachrom Bleu hairspring, I knew I had to finally order the caseback.

Here are some photos:

Be warned that while this German site has an English page, apparently the owner doesn't speak much English.

I'm quite thrilled with mine - the case is SLIGHTLY thicker with the new caseback, and my watch fits just a smidge tigher - but not enough to even let out a space in the fine adjustment.
