URWERK - UR-101 Green Mamba Limited Edition Watch
The URWERK UR-101 Green Mamba marks a striking return to the origins of independent Swiss watchmaking. Inspired by the original UR-101 unveiled in 1997, this contemporary interpretation combines a deep black case with an electrifying green time display. Limited to just 50 pieces worldwide, the Green Mamba celebrates URWERK's unconventional approach to horology, bringing one of the brand's founding designs into a bold new era.
Housed within a 41mm black PVD-coated steel case, the watch features URWERK's signature wandering-hour display, with two rotating satellites indicating the hours alongside the minutes. Vivid green SuperLumiNova enhances visibility against the darkened architecture, while a glare-proofed sapphire crystal protects the distinctive display. Powering the timepiece is the UR-1.01V self-winding calibre, operating at 28,800 vibrations per hour and delivering a 48-hour power reserve.
Completing the design is a black rubber strap with calfskin lining and a black DLC-coated steel pin buckle. Measuring just 10.3mm thick, the UR-101 Green Mamba combines distinctive aesthetics with refined proportions. A rare expression of URWERK's pioneering spirit, this limited-edition luxury watch offers collectors a remarkable piece of contemporary independent horology.

THE EVOLUTION OF AN ICON
A Bold Return to URWERK's Watchmaking Origins
The URWERK UR-101 Green Mamba Limited Edition revisits one of the most significant designs in the brand's history. First introduced at Baselworld in 1997, the original UR-101 established a distinctive approach to mechanical timekeeping, replacing conventional hands with an innovative wandering-hour display. Nearly three decades later, the Green Mamba reinterprets this pioneering concept with a striking new visual identity.
The design draws its character from the contrast between its black PVD-coated steel case and vivid green indications. Inspired by the elusive green mamba, the watch creates an almost futuristic appearance, with its illuminated display emerging from the darkness. The asymmetrical case and unconventional time presentation reflect the creative vision of URWERK co-founders Felix Baumgartner and Martin Frei.
Produced in a limited edition of just 50 pieces worldwide, the UR-101 Green Mamba represents an important connection between URWERK's heritage and its contemporary watchmaking philosophy. Combining an automatic movement with the brand's signature satellite-hour complication, this distinctive timepiece is designed for collectors who appreciate mechanical originality and independent Swiss horology.

URWERK - UR-101 Green Mamba FAq's
The UR-101 Green Mamba celebrates one of the earliest creations in URWERK's history. Originally unveiled in 1997, the UR-101 helped establish the brand's unconventional approach to displaying time and its distinctive mechanical architecture.
The Green Mamba introduces a contemporary black and green colour scheme while preserving the fundamental design principles of the original. With production restricted to 50 watches worldwide, it offers collectors a rare opportunity to own a modern interpretation of a historically important URWERK model.
Unlike traditional watches that use central hour and minute hands, the URWERK UR-101 Green Mamba features a wandering-hour complication incorporating two rotating hour satellites.
As the mechanism operates, the relevant hour travels along a curved minute scale, allowing the wearer to read the time through a moving numerical indication. The hour and minute markers are coated with SuperLumiNova, providing a vivid green appearance and improved legibility in low-light conditions.
This unconventional system is a defining feature of URWERK's approach to mechanical watchmaking.
The UR-101 Green Mamba is powered by the UR-1.01V self-winding mechanical calibre, developed to support its distinctive wandering-hour display.
Operating at a frequency of 28,800 vibrations per hour (4 Hz), the movement incorporates 28 jewels and provides a power reserve of approximately 48 hours.
Its construction incorporates copper, brass and ARCAP P40, with finishing techniques including snailing, sandblasting, satin-brushing and chamfered screw heads. These details reflect the mechanical precision and attention to finishing associated with URWERK's independent watchmaking.
The URWERK UR-101 Green Mamba is limited to just 50 pieces worldwide, making it an exclusive addition to the brand's collection.
Its restricted production, distinctive black and green design and connection to URWERK's original 1997 model make it particularly appealing to collectors interested in independent Swiss watches and unconventional complications.
