Historical significance
A. Lange & Söhne Odysseus 40 mm Skeletonised 18k sits within A. Lange & Söhne's Odysseus line, introduced in 2022. It carries the house codes established since 1845 — 18k rose gold case, skeletonised dial and in-house automatic micro-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.
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

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.
