NOMOS Tetra Basalt | Ref. 440

The NOMOS Tetra Basalt embodies elemental sophistication through its minimalist square design and deep volcanic-inspired hue. The basalt-gray dial evokes strength and calm, its mineral tone lending a grounded yet striking presence on the wrist. Contrasting accents of anthracite, fuchsia, and yellow in the sub-seconds dial bring unexpected vibrancy, while the rhodium-plated hands and polished stainless steel case create a harmonious balance of modernity and refinement. A symbol of contemporary German craftsmanship, this timepiece seamlessly transitions from day to evening, complementing silver jewelry and tailored style alike. Ref. 440 Inside, the Tetra Basalt is powered by the hand-wound DUW 4001 caliber from NOMOS Glashütte, featuring the brand’s proprietary NOMOS swing system for exceptional precision. At only 6.5 millimeters thick, this ultra-slim watch offers effortless wearability and understated luxury. With its architectural case, double lugs, and timeless aesthetic, the Tetra Basalt reflects the essence of Bauhaus-inspired design, clean, balanced, and enduringly elegant.
