Designer

Reinhard Meis & Günter Blümlein

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 Lange 1 44 mm Blue Quartz sits within A. Lange & Söhne's Lange 1 line, introduced in 1954. It carries the house codes established since 1845 — quartz tpt case, blue "grande tapisserie" dial and in-house tourbillon, manual-winding — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

  • The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
  • The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

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.
