The Dietrich OT‑1 isn’t just a watch—it’s a manifesto in steel and light. Launched in 2014 by French designer Emmanuel Dietrich, the OT‑1 was the inaugural model in his Organic Time series—a collection rooted in biomorphic form, architectural layering, and surprising visual depth. Dietrich, a Paris‑educated designer with 20 years of experience under his belt, set out to create something utterly different at an accessible price point

Encased in 316L stainless steel with black PVD coating, the cushion-shaped body measures 46 mm by 48 mm across with a height of 13.7 mm, weighing just 128 g—all balanced for wrist comfort, and fitting surprisingly smaller in person than on paper.

The dial is the heart of the watch’s identity. Composed of four concentric layers—alternating between sun‑brushed and vertical‑brushed dark grey—it builds from the movement itself up to the sapphire crystal. A rotating six‑pointed star replaces a standard seconds hand, sweeping past a partial sub‑dial, while a 24‑hour indicator at 9:30 reveals time in half-shadow, both presented with bright green Super-LumiNova accents.

Leaf-style hands, also lumed in vivid green, resemble sprouting shoots—tiny bursts of life set against industrial geometry. Beneath it all, the Miyota 82S7 automatic movement provides 40–48 hours of power reserve, hacking seconds, and day-night tracking—nothing pretentious, but entirely purposeful.
