"Sorry, could you tell me what time it is..." Sure, it's quarter past seven. "...in Geneva?" Sorry - quarter past eight. "And the date?" No problem, it's the 15th today. "Don't suppose you know what phase of the moon we're in?" Leave me alone.
Now, we're not saying you're likely to encounter the above request, but on the off-chance we can now recommend you the perfect timepiece.
In celebration of its 175th anniversary, Patek Philippe is releasing the bizarrely-named World Time Moon - a watch that incorporate's the manufacturer's mechanical skills and design flair. In addition to the self-winding mechanical movement showing 24 world time zones, the lower half of the watch face is given over to indicating the phases of the moon - marked by the passage of two highly rendered moons on metallized glass discs.
These complex workings are housed within a supremely elegant white gold 39.8mm case, with a hand-stichted Alligator strap. With only 1,300 set to be made, you'll have to move faster than a lunar body if you're hoping to get your hands on one. We hear they're particularly popular with the Gothic crowd.
