Nomos Glashütte 437 Tetra Ochra
Drawn from pigments once treasured by artisans and ancient Egyptian royalty, Tetra Ochra glows with golden light. With its strikingly square case, this watch balances contemporary aesthetics with artisanal tradition. It also represents a philosophy—that true brilliance is found in the harmony of craft and character. The hand-wound caliber DUW 4001 at work within illustrates this with meticulous precision.
The Tetra model is known for its distinctive square case, with double lugs adding a decorative touch.
The sub-seconds dial combines accents in red and two contrasting shades of yellow to create a distinctly personal timepiece that reflects the wearer’s own sense of style.
The ocher yellow dial of this watch pairs effortlessly with gold—and silver, thanks to the rhodium-plated hands.
At work within: the manual DUW 4001 caliber from NOMOS Glashütte, which features the NOMOS swing system—our proprietary escapement.
At just 6.5 millimeters in height, this slender dress watch sits elegantly on the wrist. The gently angled lugs ensure a perfect fit.
Made in Glashütte, Germany: Precision timekeeping, award-winning design, and exceptional craftmanship—perfect all around.
Crafted for character—and as an elegant companion on the wrist.
