Not to mention the (to my eye) more pleasing pushers and lug design of the original.
Sometimes the brands seem to act like they make cars...when a new generation provides new levels of performance or capability. In watchmaking, by contrast, you can readily compare new and old models.
I guess one might argue that the simplified purchase experience and manufacturers warranty may be worth a premium...but the value of that is in the eye of the customer.
Cheers,
