The Grande Class Open this year faced a new challenge, a complication capable of showing the time simultaneously in 24 different locations in the world: Tokyo, Paris, New York and even Hong Kong at a glance. Thanks to a rotating disk anchored by the hour hand, it is possible to tell the time in any time zone and, in addition, determine whether it is night or day with the help of the sun or the star pictured on the disk. This is easily done by setting the city you are in at twelve noon and activating the crown situated at 11 o’clock.
Moreover, the Grande Class Traveller Open Multicity has a Grande Date with a three-disk patented exclusive mechanism that enables the date to be displayed very visibly occupying minimal calibre space.
To these technical features we have added a totally unique design displaying the cities on a spiral, giving the dial a sophisticated aesthetic in contrast with the sober 46 mm case. It is available in two versions: rose gold - classical and precious – as well as the more modern stainless steel. And of course a sapphire glass caseback, integrated black crocodile strap, triple folding clasp and the well known love for detail that is typical of all Zenith timepieces.
