When A. Lange & Söhne re-emerged from East Germany in 1994, the Lange 1 was the watch that announced them. Off-center main dial, the big-date complication that defined the modern haute-horlogerie category (big-dates predate the Lange 1.
IWC's Da Vinci Perpetual ran one in 1985, but the Lange 1 is the design that made the complication a flagship feature of a flagship watch), 38mm case, hand-wind. The current 191.039 is the fifth-generation Lange 1 (caliber L121.1, launched 2015), with subtle dial proportion tweaks and a refined power-reserve indicator.
Designed by Günter Blümlein and Reinhard Meis, the Lange 1 launched in 1994 alongside three other references that established Lange's design vocabulary. The big-date was inspired by the historic Dresden Semper Opera House clock. The L121.1 refined dial proportions using the golden ratio and improved chronometric stability.
Available in red gold, pink gold, white gold, yellow gold, and platinum.
Common things to check: case-material verification (the price difference between platinum and pink/yellow gold is substantial, verify hallmarks on the case-back); papers (a Lange 1 without papers in this price bracket is essentially unsellable at market, provenance is everything); dial originality (the off-center Lange 1 dial is the most-imitated layout in modern haute-horlogerie; verify dial finishing under loupe); the hand-engraved 'A. Lange & Söhne' wordmark is hand-finished, replacements aren't field-feasible; case finishing (Lange's polished/brushed alternation is hand-applied, over-polished cases lose definition).
