I like the modernity those many shades of grey bring to the watch. And the contrast between this modern finishing and the "tradition" of the subscription_watch-like movement is for a great re-interpretation of Breguet history and DNA.
I'll add here that since the watch wears much bigger than it is thanks to the quasi absence of bezel, the 37mm version is more than enough. I see the trick they played with the 40mm version which shares the same movement as the 37mm but with a larger case and dial as bad marketing.... but that's only my opinion.
