Interesting, who is the builder quoted?
I very much like the ceramic Sub I bought from Prowatch-Polo (whatever happened to him?), can't find any big flaws on it, seems to be truly well made.
But I don't use the glide-lock function at all, guess I fear it will eventually get messed up.
That's a real weakness in the rep world - often you can't use the functions of the original design - chronos, waterproofnesss etc.
