Last year completed the 25 years of Lange 1, a watch that marked the revival of A. Lange & Söhne and perfectly epitomizes the Saxon brand’s watchmaking philosophy. As a part of the celebrations, A. Lange & Söhne released ten anniversary editions of Lange 1’s different versions, including the Lange 1 Time Zone – a watch for people who travel, work, and communicate across the globe. For 2020, the brand has revealed a new version of the world time watch which arrives with several updates, along with a new manufacture caliber. The latest Lange 1 Time Zone retains the overall design of the predecessor and the dimensions of the case. It still has a diameter of 41.9 mm and a height of 10.9 mm. The dial displays the time at home and a second zone at a glance, with the home time subdial taking up a larger real estate on the dial than the world time – we usually get to see the opposite in world time watches. One of the more prominent changes in the new iteration of the Lange 1 Time Zone comes in the form changed day/night indicators for home time and zone time. While originally the watch had rotating arrow hands, the indicators have moved to the centers of the two time circles. The new ring-shaped indicators are not only more intuitive to read, they are now a lot more homogenous to the design by seamlessly blending into the time displays.
Another convenient feature on the new Lange 1 Time Zone is the innovative daylight saving time indications. The golden arrow applique at 5 o’clock that indicates the reference location for the zone time on the city ring has a tiny aperture. When the aperture turns red, it indicates that the corresponding city has a daylight saving time regime and the time has to be adjusted accordingly. For other cities, the display appears on a bright background. Other features like the convenient adjustment of the second time zone based on a switchable city ring with 24 time zones and the unique synchronization mechanism that makes it possible to transfer zone time from the smaller to the larger dial have been retained from the predecessor. What’s new for the 2020 iteration is the new manufacture caliber L141.1. the new movement’s 72-hour power reserve is achieved with only one spring barrel. Additionally, it also gets a classic screw balance and a freely oscillating balance spring crafted in-house and calibrated for a frequency of 21,600 semi-oscillations per hour. The sapphire-crystal caseback gives a view of the beautifully appointed movement, which includes the three-quarter plate made of untreated German silver, screwed gold chatons, blued screws, an elaborate whiplash precision index adjuster as well as hand-engraved balance and intermediate-wheel cocks. The new Lange 1 Time Zone is available in three versions: white gold case with black dial, pink gold case with argenté dial, and yellow gold case with champagne dial. The last one is limited to just 100 examples.
