As a toolwatch...
This is a very solid watch, the EWA too, but the esthetic of the EWC is even more appealing, and much more balanced, well, to me, again...
Yep, the RG EWA is the Rossi Edition.
Here the EWC in SS ( Boutique Edition, which is a very LE ):
Here the Platinum Edition ( also a LE ) of the same odel ,with a stunning ruthenium dial...
Best.
