The initial idea according to Corrigia was to have a watch with whom he could quickly change his 5,5-6mm thick straps. Therefore the distance in between the case and the end of the lug is a few mm longer compared to a panerai. Than of course is gotta be a divers watch. Therefore a protection of the crown. There are many other brands who have a crown protection eg. Omega ๐ Than a watch out of bronze with the maximal amount of bronze to enjoy the patina. Therefore you have wider bezelโฆ.
They might look somehow similar but to me they are actually pretty different on mine point of view.
At the end people will say that all my panerai watches look the same - lol - and i will deny ๐๐๐ โฆ
