Van Cleef & Arpels Midnight Planetarium Watch
If there was ever an item that should be rank top of my "things I wish I was ridiculously rich for," then this would be it!
This is part of Van Cleef and Arpel's Poetic Complications line of wristwatches. Think "Just like the anniversary clocks that my grandparent's have in their dining room that moves around in some weird time-dance every hour, on the hour," except a lot less...tacky.
There are a few different designs, all very breathtaking, but by far - the Midnight Planetarium is unparellelled.
