For the pleasure of the eyes: Ulysse Nardin Marine Tourbillon Close up.
I worked form an official picture, and focused on the enamel grand feu dial.
Even if I am not fan of tourbillons in a plain dial, I must say that I would happily make an exception for this one.
M4... You are a lucky guy to own such a marvel.
Best,
Nicolas
