The reference the company restarted on. Calibre L901.0 was Lange's first movement in over forty years, and it set the construction rules everything since has followed: a three-quarter plate rather than separate bridges, untreated German silver that oxidises to a warm tone instead of being plated, and a balance cock engraved by hand — so no two are identical, and the engraver's work is the one part of the watch that cannot be repeated exactly.
- German silver contains no silver. It is a copper-nickel-zinc alloy, used because it is harder than brass and because Lange leaves it unplated.
- Every balance cock is hand-engraved individually, which is why the pattern differs between two otherwise identical watches.
- The three-quarter plate and untreated German silver are structural to how Lange builds movements, not finishing options.
