It fit great and looks amazing.

René K. (Nieuwaal, NL)
Nice retro crystal.

Purchased for my Tudor Black Bay Pro homage watch. That is a GMT and requires sufficient space for the four hands. That is no problem with this crystal.

Stuart S. (Winscombe, GB)
Double Dome Crystal

The AR coating seems much improved since my first crystal a few years back.

Flat Sapphire Crystal

Very clear

Stuart S. (Houston, US)

Prefer to use Namoki crystals. The fit is spot on, and the gaskets are better.
