A. Lange & Söhne - Lange 1 Fuseaux horaires

The LANGE 1 TIME ZONE makes it particularly easy for travellers to keep track of time when they cross over from one time zone to the next. Its dial indicates home time and the current time in a second time zone at a single glance. The applicable time zone can be set with pushbutton convenience. For this purpose, the watch features a rotating ring with the names of 24 cities that represent the respective time zones. A push piece moves the ring forward in steps of 15 degrees to the East, causing the hour hand of the subsidiary dial to advance in one-hour increments as well. An ingeniously designed synchronisation mechanism allows the zone time displayed on the subdial to be effortlessly swapped to the main dial. The hands in the small dial then assume the positions previously held by the hands in the large one.

With the new LANGE 1 TIME ZONE in the noble white-gold case, these settings can now be effortlessly performed in the dark as well. This is assured by luminous hands and appliques in rhodiumed gold on the decentrally arranged main and subsidiary dials
and in the power-reserve indicator. Thus, with its luminescent face, this A. Lange & Söhne paragon always delivers a reliable indication of the time en route and at home, by day and by night, around the globe.

The heart of this new member of the prominent LANGE 1 family is the manufacture calibre L031.1. In terms of horological finesse, it offers everything that explains why aficionados around the world associate the name A. Lange & Söhne with the ultimate in watchmaking artistry: typical quality hallmarks such as the three-quarter plate made of untreated German silver, screwed gold chatons, the twin mainspring barrel for a^power reserve of more than three days, the elaborate whiplash precision index adjuster, the hand-engraved balance and intermediate-wheel cocks, and the ingenious outsize date display which in the LANGE 1 TIME ZONE is connected with the time displayed on the main dial. Given these assets, every trip is a moving experience.
