LANGE 1 TIME ZONE MODEL, REF. 116.025, CASE NO. 172'492, CIRCA 2008

Introduced in 2005, the Lange 1 Time Zone is a prime example of the brand's exceptional watchmaking skills, skillfully blending several complications, aesthetics, readability and simplicity of use. The model features two eccentric dials each with its own independent day/night indicator. The wearer can simply select the desired time zone to be shown on the larger dial, be it home time, local time while traveling, or any other time zone they'd like, thanks to an effortless adjustment system. A pusher and revolving city ring make it easy to set the second time zone: each press advances the secondary dial's hands by an hour and one notch. The oversized date is automatically synchronized with the larger of the two dials.

Powering the watch is the manufacture's hand-wound calibre L031.1, featuring the brand's signature three-quarter plate made of untreated German silver and decorated with Glashütte ribbing. When fully wound, the twin mainspring barrels provide an impressive three-day power reserve. Perfect legibility is guaranteed by A. Lange & Söhne's patented twin-disc mechanism for the oversized date display, one of the brand's most recognizable features. It furthermore has a hack feature, activated when the crown is pulled out, a characteristic very appreciated by collectors looking to set their watch to the second.

A second generation of Lange 1 Time Zones was presented in 2020, featuring a new updated calibre L141.1, equipped with an intuitive indication of daylight-saving time and a newly designed rhodium-coloured dial made of solid silver.
