URWERK has long been known for bending the rules of haute horlogerie, but its latest creation, the UR-150 Blue Scorpion, takes this reputation further into uncharted territory. Limited to just 50 pieces and priced at CHF 90,000, the new timepiece transforms timekeeping into a mechanical performance—part kinetic art, part horological rebellion.
Beneath its domed sapphire crystal, the UR-150 presents a hypnotic spectacle. Three satellites orbit within a flying carousel, while a retrograde hand sweeps across a 240° arc, only to snap back in a lightning-fast return at the turn of each hour. This perilous ballet, faster than the eye can catch yet impossible to ignore, reshuffles time with unnerving precision. In Martin Frei’s words, it is “a game of uncertainty and wonder,” where satellites pivot and regroup before delivering clarity in an instant.


To make this mechanical theatre possible, the watch employs a cam-and-rack system inspired by automatons, synchronized with a speed governor to control energy. Each satellite is tilted ten degrees for legibility, a seemingly small adjustment that demanded significant complexity. For master watchmaker Felix Baumgartner, the achievement is less about component count and more about harmony: power, inertia, and fluidity working as one.
The retrograde hand itself frames the hour satellite in a skeletonized embrace, before pouncing on the next hour with a precision that borders on alchemy. Every spring, every gear, has been meticulously designed for maximum energy efficiency, a hidden choreography that ensures the spectacle remains flawless.


Despite the drama of its name, the UR-150 Blue Scorpion exudes refinement. Smooth lines, organic forms, and an ergonomic case lend elegance, while blue ALD-coated components, titanium finishes, and hand-painted Super-LumiNova details underscore its modern artistry. It is as much a bold aesthetic statement as it is a technical triumph.
The case, crafted in steel with a titanium back, measures 42.5mm by 51mm with a height of 14.8mm, designed to sit comfortably on the wrist. Inside beats the Caliber UR-50.01, operating at 28,800 vph with a 43-hour power reserve, powered by an automatic winding system governed by twin turbines. The strap, a high-performance hybrid rubber, completes the watch’s fusion of performance and sophistication.
The watch’s exclusivity is amplified by its symbolic edition size: only 88 pieces, a number considered lucky by founder Roger Dubuis, highlighted on the tachymeter scale as a subtle tribute. Every one of its 333 components meets the demanding standards of the Geneva Seal, with 16 distinct hand-finishing techniques applied to ensure perfection.


In essence, the UR-150 Blue Scorpion is more than a timepiece—it is an object of intrigue, a design that blurs the boundaries between fine watchmaking and kinetic sculpture. For collectors, it represents the rarest of unions: clarity achieved through chaos, elegance born from audacity.
URWERK, since its founding in 1997, has remained steadfast in its mission to rewrite the rules of time. With the UR-150 Blue Scorpion, it does so again, reminding us that horology at its highest level is not just about measuring minutes but about shaping moments of awe.
