Crafted to celebrate the company’s 175th anniversary, the Patek Philippe World Time Moon Watch blends old and new by pairing the company’s world time mechanism that first appeared in the 1930s with an all-new central moon-phase display.

The multi-part dial features two rotating scales for the world time function (the outermost scale lists cities, and the inner rotating scale doubles as a 24-hour dial and day/night indicator. The new moon phase display is especially interesting because it is the first time Patek has rendered the moon so realistically, here on two superimposed metallized glass discs.

The hour hand is a new design meant to recall the Southern Cross constellation – completing a poetic design trifecta on the watch dial consisting of the earth (cities), moon (center display), and stars (the hour hand). Another nod to the brand’s anniversary is visible on the dial – the limited edition World Time Moon uses Patek Philippe’s hometown of Geneva to represent Central European Time. (Paris is usually listed for this time zone.)

Limited to just 1300 examples, the USD 48,000 Patek Philippe World Time Moon Watch measures 39.8 mm and comes with a hand-stitched alligator strap.
