A timepiece for globetrotters is the A. Lange & Söhne Lange 1 Time Zone that is now available in platinum with a rhodium colored dial. A watch that displays the time at home and in another time zone in one glance with ring-shaped day/night displays and the daylight-saving time indication for the second time zone expand the already high degree of functionality. This year, the monochrome color combination adds a timeless elegance to the technical sophistication.

The simultaneous display of two zone times is one of the most useful additional functions in precision watchmaking and is highly valued by globally interconnected watch connoisseurs. In 2005, A. Lange & Söhne endowed this complication with a distinctive face in the Lange 1 Time Zone. In addition to home time, this unique timepiece displayed the time in a second zone, easily selected thanks to the cities on the city ring representing 24 time zones.

In its second generation, presented in 2020, the cosmopolitan model was equipped with the new manufacture calibre L141.1, featuring an intuitive indication of daylight-saving time. Now, the new edition of the Lange 1 Time Zone showcases a 41.9 mm case in .950 platinum combined with a rhodium-colored dial made of solid silver, resulting in a decidedly classic look.

By placing the ring with the 24 reference cities on the periphery, the distinctive, off-centered dial architecture of the Lange 1 watch family is not impaired. Home time and zone time, the outsize date and the power-reserve indicator are all clearly visible at any given time. While the larger time circle indicates home time, the smaller time circle displays the time in a second time zone with a pointer pointing to the corresponding city on the 24-city ring.

When the corrector button at 8 o’clock is actuated, the city ring switches in the easterly direction by one time zone. At the same time, the hour hand in the small subsidiary dial advances by one hour and now indicates the zone time of the city —and corresponding time zone— at which the gold applied arrow marker points.

The indication of daylight-saving time constitutes a refined technical feature. A color segment in the arrow indicates whether the selected city and time zone implement daylight-saving time; if this is the case, the small aperture is filled in red, and if standard time is observed in this location all year round, the background remains unchanged.

To distinguish between day and night in both time zones, the Lange 1 Time Zone features colored ring-shaped day/night indicators linked to the hour hands. They are placed in the center of each time circle and inform the wearer whether the respective time indication is valid for the first or the second half of the day. When the hour hand is in the dial-colored area, the display refers to the interval between 6 a.m. and 6 p.m.; when the blue background appears, it refers to the interval between 6 p.m. and 6 a.m. Perhaps not the most intuitive way to indicate this, but definitely a convenient indication to have on a world timer.

Additionally, the Lange 1 Time Zone is endowed with an ingeniously designed synchronization mechanism that allows the zone time to be transferred from the smaller subsidiary dial to the larger one, thus making it possible to define a new main time as home time. When the crown is pulled in the second position, the times of both zones can be adjusted synchronously. However, if the time zone correction button is pressed and held, the hour hand of the time zone dial will be stopped in its position. Now, the defined new main time can be set independently of the time zone. Finally, it may be necessary to correct the outsize date, which is connected with main time, by actuating the date correction button at 10 o’clock.

The manual wound calibre L141.1 is fully visible via the display case back and when fully wound, it provides a power reserve of 72 hours.
