Independent Geneva watchmaker URWERK has released the UR-101 Green Mamba, a limited edition of 50 pieces. The timepiece pairs a 41mm black PVD-coated steel case with an emerald-green wandering-hour display.
Why it matters
The release shows how independent Swiss maisons continue to use distinctive complications and limited runs to stand apart in the luxury watch market. Its small production run means access will be restricted to a limited group of buyers.
The caliber UR-1.01V beats at 28,800 vph (4 Hz) on 28 jewels and offers a 48-hour power reserve. The case is 10.3mm thick and pressure-tested to 30 meters / 3 ATM.
The players
URWERK
An independent watchmaker based in Geneva known for unconventional wandering-hour displays and avant-garde case designs.
The details
Time is read through wandering hours on two satellites, with minutes indicated along an adjacent scale on the emerald-green circular segment. The black rubber strap has black calfskin lining and is fastened with a black DLC-coated steel pin buckle.
Timeline
1997: URWERK's founding design was first shown at Baselworld.
The UR-101 Green Mamba was first shown at Baselworld, where the trade fair featured the model.
Roadmap
The UR-101 Green Mamba extends the wandering-hour concept URWERK introduced at Baselworld in 1997 into a new limited color variant. It reflects the continued use of signature complications by independent Swiss maisons to differentiate from mass-produced luxury brands.
Buyers interested in the UR-101 Green Mamba face a CHF 33,000 price excluding tax and a run of only 50 pieces. The limited availability means prospective owners will need to act quickly if they want one of the pieces.
The takeaway
Collectors looking at limited independent watches should weigh production size and price together, since a 50-piece run at this price point narrows availability quickly. Checking authorized URWERK retailers directly is the most reliable way to confirm stock.
