When it comes to travel-focused timepieces, the Lange 1 Time Zone ranks up there with the best of them. For 2020, the German watchmaker is updating the watch with a slightly revised dial and an all-new movement. The revisions to the dial includes a change to the day/night indicators, which have been moved to the center of the sub-dials, improving readability while creating a cleaner, more streamlined look. An arrow applique has also been added at 5 o'clock, indicating the reference city, showing red for daylight savings and standard time when white. The second time zone is displayed on the smaller sub-dial and can be easily changed with the corrector button at 8 o'clock. The updated Time Zone also features a brand new L141.1 movement and a 72-hour power reserve that is achieved with a single spring barrel.
