A. Lange & Söhne 136.029 Lange 1 Time Zone White Gold Black Dial (2021)

The Lange 1 stands as A. Lange & Söhne's most iconic modern reference — announced October 24, 1994 as one of the four foundational watches following the brand's revival after decades of dormancy imposed by East German communist expropriation. Its asymmetric off-center dial layout was revolutionary, and the outsized date display was the first in modern watchmaking history. The Lange 1 Time Zone debuted in 2005 as the traveler's iteration, and reference 136.029 represents the third-generation update released in 2020 — the first movement change to the Time Zone in fifteen years, powered by the new in-house Caliber L141.1. Configured in white gold with a black solid silver dial, this remains one of the most sophisticated dual-time wristwatches ever produced.

The 41.9mm case in 18-karat white gold measures 10.9mm thick, framing the black solid silver dial with applied white gold hour markers. The signature layout displays home time with Roman numerals at upper left, second time zone at five with Arabic numerals, outsize date at twelve, small seconds, power reserve indicator, and a rotating city ring for 24 reference cities operated by the pusher at eight. The hand-wound Caliber L141.1 — 448 parts with three-quarter plate in untreated German silver and hand-engraved balance cock — delivers a 72-hour power reserve, completed by a hand-stitched black alligator strap with white gold pin buckle.
