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, thus further expanding the functionality of this watch. Now, the new edition of the LANGE 1 TIME ZONE showcases a 950-platinum case combined with a rhodium-coloured dial made of solid silver, resulting in a decidedly classic look, a first for this model.
