As the 1966 Blue Moon showed, moon-phase watches can be a draw without the need for extra features, but I've always felt a perpetual calendar best shows off a lunar compli­cation The Audemars Piguet Royal Oak Selfwinding Perpetual Calendar Ultra-Thin is as cutting edge as watches get The design is gorgeous, of course, featuring the iconic industrial octagonal silhouette of the Royal Oak case, but the genius is the thin­ness of the watch and its movement.

Finally, we have the most gorgeous moon-phase indicator I've seen in a 2019 watch, the Vacheron Constantin Overseas Perpetual Calendar OK, OK, if a watch costs HK$610,000 it had better be a looker as well as a technical marvel Inside, the watch is a calibre 1120 movement with 40 hours of power reserve.

The ultra-thin 41.5mm case is made of pink gold and the watch comes with a choice of leather or rubber straps. . Source
