For the pleasure of the eyes: Lange 1815 Moon Phase Emil Lange in Rose Gold.
Rose Gold cases and Black Dials work very well together.
The 1815 MP Emil Lange is no exception to that. Even if I favor the platinum version, it doesn't lack charm, in rose gold.
This one is one of the vey rare colored gold watches I would consider having, one day, to make a pair with my platinum.
