I have a couple of the IWC/Porsche Design watches on which this (as well as the P'6530) is based. Obviously, I can't comment on the specifics of Eterna's execution of the design, but the design itself is inherently comfortable, light and modern, yet classic. If you've been tempted by the (now vintage) IWC versions, but are afraid of the vintage aspect, or of paying for IWC service, this watch looks to be a great option.
