Designer
In-house design studio
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
A. Lange & Söhne Zeitwerk 42 mm Blue Carbon sits within A. Lange & Söhne's Zeitwerk line, introduced in 2006. It carries the house codes established since 1845 — carbon tpt case, blue "grande tapisserie" dial and in-house automatic with 22k gold rotor — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history
A. Lange & Söhne has spent more than 181 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Lange 1, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Ferdinand Adolph Lange established A. Lange & Söhne in 1845, working from Germany at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every A. Lange & Söhne calibre produced today.
