This model was introduced in 2020. The dial is crafted from solid silver and graced with solid-gold appliques and hour markers. The hands are made of white gold.

In the new LANGE 1 TIME ZONE, the day/night indicators for home and zone time have been shifted to the centres of the two time circles. Together with the hour hand, they inform the user whether the time indication applies to the first or second half of the day. The new indication of daylight-saving time in the gold applied arrow marker offers an additional time parameter: if a red segment appears, the selected city implements daylight-saving time. The manufacture calibre L141.1, that assures the precise rate of the watch, is new as well.

The additional “second time zone” function is a particularly popular complication, especially because more and more people travel, work and communicate intercontinentally. Thus, the LANGE 1 TIME ZONE is the perfect companion for frequent travellers and cosmopolites: it shows home time and the time in a second zone at a single glance. Each of the 24 time zones is represented by a city name on the city ring. The city ring and the zone time can be simultaneously advanced in increments, corresponding to an eastbound trip around the world.
