NOMOS Glashütte Tetra plum

Tetra plum, the new timepiece from NOMOS Glashütte, features a rich purple dial that pays tribute to nature’s bounty. Its stainless steel case measures 29.5 by 29.5 millimeters.

The silver accents on the numerals, indexes, and hands add a sophisticated touch to this appealing timepiece. The eye-catching complication between twelve and one o’clock is a power reserve indicator, reminding the wearer when it is time to wind the watch.

Tetra plum is powered by the hand-wound NOMOS caliber DUW 4301, which also features the NOMOS swing system—itself a fruit of many years of labor. This proprietary escapement is designed and developed in-house, which is an exceptional achievement in the watchmaking world.

The round sub-seconds dial adds a contrasting touch to the clean-cut corners found elsewhere in Tetra. The overall aesthetic is harmonious and modern, with a timeless elegance that suits a wide range of wrists. Tetra plum will be available at selected retailers from October.
