The Geophysic is less famous than the Reverso and the Polaris.
When you have a Reverso or a Polaris on the wrist, people notice it.
When you have a Geophysic on the wrist, only Watch nuts notice it.
That is a fact based on several years of tests.
No doubt that the Tribute to Geophysic won't change this perception. A Watch which is more discete than the TT Polaris, TT DSA or TT Reverso.
As for the plexy versus the sapphire, like you I prefer the plexy, but at least the sapphire is slightly domed, and, personally, I don't find it is a big issue.
Best, and thanks for your elaborated input, my friend.
