Article Summary

August 7, 2006 For two centuries, perhaps the rarest of watchmaking complications has been the equation of time. Measuring the difference between the length of the solar day which constantly varies over the course of the year and the length of the standard 24 hour civil day, an equation of time display has graced only the most exclusive watches and clocks. Even more refined and exclusive has been an equation of time display which shows both solar time and civil time with two separate minute hands. In all of watchmaking history, only a handful of the most important clocks and pocket watches have featured this form of dual time, “equation marchante” display and they have been so exclusive that nearly every one has been an historically significant piece. Blancpain unveiled a limited series of 50 pieces of the first equation marchante wristwatch in 2004. Now to mark the seventh anniversary of Blancpain’s partnership with the Monaco Yacht Show, Blancpain has created a special limited edition Le Brassus series watch featuring an evolution of its equation marchante movement.
