Deep black and vivid green. Just two colors are enough to bestow a hypnotic visual presence upon the classic UR-101. With the new URWERK UR-101 Green Mamba, the independent Swiss manufacture returns to an essential form of radicalism: a case that absorbs light and a starkly contrasting dial that emerges directly from the shadows.
A Return to the Origins of Time in Motion
Originally presented at Baselworld in 1997, the UR-101 laid the conceptual foundations for URWERK: a time display liberated from traditional hands and a vision of watchmaking mechanics as a sculptural language. Nearly thirty years later, master watchmaker Felix Baumgartner and artistic director Martin Frei reinterpret this icon through a new lens of instinctive simplicity.
In this edition, the signature wandering hours display driven by twin satellites traverses an emerald green arc. The numeral emerges in a technological, luminescent hue—evoking spaceship control panels or the watchful eyes of a mamba—all housed within an asymmetrical case finished in Panter Black coating as a pure sci-fi aesthetic nod.
Compact Architecture and Avant-Garde Spirit
Featuring a restrained size of 41mm in diameter and 10.3mm in thickness, the black PVD-coated steel case acts as a protective shield, rendering the object itself almost invisible to allow the time indication full prominence. Inside beats the self-winding UR-1.01V caliber, running at 28,800 vibrations per hour (4 Hz) and hand-decorated with traditional techniques including circular Côtes (azurage), sandblasting, and hand-beveled screw heads.
Strictly limited to 50 pieces worldwide, with a price tag of CHF 33,000 (excluding taxes).
