The Lambda represents the very best that Nomos is capable of. It features an elegant tripartite gold case and a clean dial typical of the Nomos design language. The movement is the hand-wound caliber DUW 1001.
Reference 931 has a 42mm white gold case and a white silver-plated dial.
The hand-wound caliber DUW 1001 is a high-end movement created by Nomos according to the traditional Glashütte codes of watchmaking. It features 29 jewels, a double mainspring barrel providing it with 84 hours of power reserve, a power reserve at 12:00 and a small seconds indicator at 6:00. The multiple polished, screwed gold chatons, the hand-engraved balance cock and beveled edges, swan neck fine adjustment, and traditional 3/4 plate are a testament to the movement's overall high quality and precision.
