There are videos on YouTube about how to change the insert. Same process only once you pop the bezel off, you remove the washer and then just push for the bezel back on.
Amazing!! Great build. I actually think a build like this looks better than gen. We are so anal about every detail that the final thing ends up being better than the ones from the factory. Stunning. Love the strap too.
Here you go. Allegedly recently serviced and everything. Not suggesting I like it as much as I like yours. Personally I like the way yours looks better. However this is likely not a Franken but an original genuine so could be a great deal for a member that prefers the way this one looks. http://forums.watchuseek.com/showthread.php?t=2608018
