I normally wear it everyday (works as well in a suit as blue jeans). The CS comes in second place, (the Dato is a distant third) I think because of the big date of the Octa that is so important to me at work. But I suppose its the typical iconoclastic dial that really seals the deal for me. Not to mention its 38 mm size that suits me perfectly. Simply said, it natually finds itself on my wrist most of the time. Of course if I had a Resonance there might be serious competition !
As for the Bordeaux, I need little prompting in that department !!
