It' difficult to argue with this logic
I too was in the market for the 1815 RG / black dial (current generation), but it didn't fit my wrist particularly well, so ended up with the VC Cornes de Vache in steel.
I am really happy I did, as the combination of silver dial, blue undertones and white metal makes it more versatile in a casual / smart casual outfit, very much like the 1815 you picked.
Well done, Sir. Enjoy this wonderful watch.
