how high is the crystal on a gen sub

[bklm1234]

I heard it's 1mm high (from the insert). But today when my coworker showed me his TT, it looks rather low (I couldn't find a ruler to measure it). It doesn't even look 1mm high. The beveling is definitely on the entire portion of the crystal sitting above the insert, which is not the case on cn subs, the beveling is only like half of the crystal above the insert. This is what I always refer to "lacking the submariner look". So gen owners please tell me how high it is, please.

The crystal is thick, beveled and nicely polished. I'm not sure what your friend has but it is a distinct characteristic of rollie subs.
