A lot of people say that the correct measurement is from 8h to 2h. That's how Patek Philippe does for instance.

And if you measure the case from 8h-2h, you get 40mm in Sub and GMT II and 38.57 in Daytona

And please, here do you measure to see only a .45mm difference?

Cheers

I believe it. My GMT ll looks big vs. Daytona. Daytona looks same as my Speedy Reduced. Bezel and lugs create optical illusion?
