Coming from Vacheron Constantin today we have a very special watch. At the 2011 SIHH, VC showed one of the most complete world-timer wristwatches ever made in the Patrimony Traditonnelle World Time. This single crown worldtimer shows every single timezone on the planet, which includes the 24 timezones, in addition to the half and quarter hour timezones. So that’s 37 timezones, without a single pusher, and it also displays day/night via an incredible rotating sapphire crystal. The watch is downright incredible, and has become one of the most desirable watches in VC’s collection. The thing is, it was only available in pink gold, until today.

First, how does it work? Well, you can watch this (very old and admittedly poorly filmed yet still interesting) movie we shot of the watch the day it was launched, being explained by VC artistic director Christian Selmoni.
