The Lange 1 is a modern classic of the watchmaking world, and since it was first introduced in 1994 the family has expanded to encompass elegant moon phases, tourbillons, perpetual calendars and more. One of the most sophisticated additions was the Lange 1 Time Zone in 2005, and 15 years after its launch the German watchmaker is giving the model a technical update with a new manufacture calibre.

The handsome watch effortlessly displays two time zones at a mere glance thanks to the layout of its signature asymmetric dial. While the larger counter displays the home time, the smaller can be set to a secondary time zone by adjusting the city ring, featuring 24 reference locations. This is easily adjustable; when the corrector button at 8 o’clock is pressed, the city ring jumps from west to east by one time zone, while the hour hand in the subsidiary dial advances by one hour.

The complication goes a step further, also indicating whether it is day or night in both home and secondary time zones. This is displayed via a rotating ring-shaped display at the centre of each subdial, featuring blue printed semicircles to indicate whether the time falls within 6am to 6pm or vice versa. The new Lange 1 Time Zone also has another convenient feature to let the wearer know whether daylight saving applies in their location. In the golden arrow positioned at 5 o’clock is a small aperture that turns red when the chosen city has a daylight saving time regime in place.

The new Lange 1 Time Zone is powered by the manufacture calibre L141.1, offering a power reserve of 72 hours. As with every A. Lange & Söhne, the movement is meticulously finished with details including screwed gold chatons, blued screws and hand-engraved balance and intermediate-wheel cocks, visible through the sapphire-crystal case back. This new model comes in three elegant dial and case combinations – white gold with black dial, pink gold and silver, and a yellow gold with champagne dial – the latter limited to 100 pieces.
