The NOMOS Tetra Gold 27 418 showcases a distinctive square shape, encased in an elegant 27.5mm 18-karat yellow gold housing. The white, silver-plated dial is complemented by striking tempered blue hands and powered by the manually wound DUW 4001 caliber. This model adheres to the renowned compact Tetra design, featuring a geometric case profile, a small seconds indicator, and a unique stepped lug construction. With dimensions of 27.5mm in width and height, and a lug-to-lug distance of 38.5mm, this timepiece is topped with a sapphire crystal that protects both the front and the case back, allowing a peek at its intricate movement. The striking gold crown and the distinctive double-stepped lugs further highlight the watch's elegant aesthetic while showcasing a water resistance of 3 atm. The finely printed indexes and square minute track can be found on the dial, which also hosts a round small seconds sub-dial situated at 6 o'clock. The central display indicates hours and minutes, while the small seconds completes the reading.

This caliber boasts 17 jewels, offers a power reserve of up to 53 hours, and incorporates the NOMOS swing system, all visible through the transparent sapphire case back.
