But, without any doubt, I would go on the Cartier Santos Skeleton.
I'm not an annual calendar fan, as I much prefer simple dates or perpetual calendars.
Simple or sohisticated, but not half way, in my very personal opinion.
The 1815 Moonphase is a very nice watch, but for once, I would go on the more original Cartier Skeleton.
I love a lot these " industrial " and modern skeleton, and somehow, this Santos share something ( in the spirit ) with the RO jumbo.
Sporty, yet elegant.
Yes, without doubt, the Cartier, for once!
Best,
Nicolas
