LANGE 1 TIME ZONE

A timekeeper for cosmopolites

In 1884, the attendees of the International Meridian Conference resolved to adopt a shared time system: the world was subdivided into 24 time zones. But the conquest of watches with time-zone displays did not occur until the 20th century, when it became possible to quickly traverse several time zones on board an aircraft. 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.

In the LANGE 1 TIME ZONE, the smaller scale shows the time in a second zone. In the LANGE 1 TIME ZONE, the applied arrow marker at 2 o’clock points at the name on the city ring which represents the time zone that is being displayed.

The large numerals scale indicates home time, the smaller one shows that of a second zone. Each of the 24 time zones is represented by a city name on the city ring. An applied arrow marker at 5 o’clock points at the name on the city ring, which represents the time zone that is being displayed. A time-zone correction pusher allows the city ring and the zone time to be simultaneously advanced by increments of one hour, corresponding to an eastbound trip around the world.
