A. Lange & Sohne recently introduced a new version of their popular Lange 1 Time Zone watch. It features a slate grey dial with a new world time ring that now includes Santiago de Chile, in place of Caracas. The change was made because Venezuela changed its time zone from Atlantic Standard Time (UTC-4) to (UTC-4:30). The watch is powered by a manually-wound Lange L031.1 caliber in-house movement.

Comprised of 417 parts, the caliber displays traditional Saxon fine finishing, including plates in untreated German silver with Glashutte ribbing decoration, blued screws, a hand-engraved balance cock, and four jewels set in gold chatons. The caliber features twin mainspring barrels, which enable a 72-hour power reserve. Balance wheel frequency is 21,600 alternations per hour.

In addition to the famous off-set time display and outsize date function, the movement animates an innovative dual timezone display with two day/night indicators and an adjustable worldtime ring. A power reserve indicator shows the status of tension remaining in the spring barrels.

The A. Lange & Sohne Lange 1 Time Zone watch measures 41.9mm in diameter and is fitted with sapphire crystals on both front and back. The strap is made in hand-sewn crocodile and features a massive gold Lange buckle complete the ensemble.
