This watch is so underrated it's ridiculous. Using the same Lemania base movement as the Patek 3970/5970, Vacheron has made a perpetual calendar chronograph that is unlike any other. It's got a unique, art-deco style that is interesting without being over the top. But the truly killer feature is the engraved moonphase disc. Check out the video review to see what it's like "in the metal".
