For their restrained use of text on the dial. Needless lines of text could have easily killed this one. Using the historic font and Omega were perfect in this reinterpretation. The Ag .925 is discreet enough that it doesn't detract. A brilliant dial, well...
I understand from the less-than-terrific local Omega boutique that there's also a 'Sedna' gold version floating around somewhere. I'd be interested to see that one too in due course.
