I called today Panerai (factory) and they could not tell.
What I learnt is that the watch is about to be discontinued (it is not being produced since some time in effect).
They will inform me next week about the definitive status if the crystal, but I am pretty sure the answer will be plexi...
I am super perplexed what to do now..being a leftie, I could go for the 372 (assuming it has sapphire), but I was so sold to the idea of a destro... π
Grazie ancora Sergio,
Alex
