Have you ever heard of swapping out the plexi crystal on the 372 for a sapphire ?
Never heard of that and not really sure why someone would even want to do that as the plexi is actually and integral part which makes this watch what it is. I don't know. some other's opinions may differ, but I like my watches to replicate the gen in as many ways as it possibly can. the plexi is actually part of the aesthetic look of that watch and without that I believe would change the way it looks and presents itself.
