Evolution
Opus Chronograph
Purple Rain
A fearless tribute to 30 years of an icon. The skeletonized chronograph reborn in bold purple, merging legacy with radical modernity.
The Icon Reimagined
To celebrate 30 years of the iconic Chronoswiss Opus, we reimagined a true classic — and gave it a bold new attitude. The Opus Purple Rain brings the iconic skeletonized chronograph into a new era, with a vibrant purple CVD-coated titanium case and a UV-reactive white strap that transforms to purple in sunlight. Its open-worked dial reveals every beat of the chronograph mechanism, framed by floating bridges and deep contrast. Limited to just 30 pieces, this is a fearless tribute to one of the most legendary timepieces in Chronoswiss history.

Movement
C.741S
At the core of the Opus Purple Rain beats the Chronoswiss Caliber C.741S — a skeletonized automatic chronograph movement refined for transparency and performance. Visible through the open architecture, it features black galvanized bridges and a CVD-coated, skeletonized rotor, adorned with subtle Côtes de Genève. With central chronograph seconds, 30-minute and 12-hour counters, a small seconds display, and an analog date function, the movement delivers both function and finesse. Operating at 28,800 vibrations per hour with a power reserve of 46 hours, it is the mechanical pulse of this reimagined icon.
Materials
Titanium Grade 5
Chronoswiss increasingly favors titanium for its lightness. It has the best strength-to-weight ratio among metals, making it highly sought after in aerospace. Additionally, titanium is corrosion-resistant and skin-friendly. For its creations, Chronoswiss exclusively selects the toughest available titanium alloy, Grade 5.
Complication
Chronograph & Date
The Chronoswiss Opus features a sophisticated chronograph mechanism with central stopwatch seconds, a 30-minute counter at 12 o’clock, and a 12-hour counter at 6 o’clock — allowing precise measurement of elapsed time. A small second at 9 o’clock ensures constant running time, while a cleanly integrated date at 3 o’clock adds daily utility to this mechanical masterpiece.
Coating
Chemical Vapour Deposition (CVD)
Chronoswiss harnesses the versatility of CVD coatings to infuse watch cases and dials with vibrant hues like blue, purple, and color-shifting tones. This complex gas-phase process enables precise, uniform coatings even on complex surfaces, optimizing for durability, resistance, and aesthetic appeal.

Innovation
The Magic Strap
The Opus Purple Rain comes fitted with a white leather strap that holds a hidden surprise: It is UV-reactive. As soon as sunlight touches the surface, the strap transforms into a vivid purple hue - a dramatic, almost alchemical shift that mirrors the energy of the piece itself. Indoors it stays crisp and clean; outdoors, it comes alive. A playful yet refined nod to transformation, time, and light.
Our Vision
When Chronoswiss introduced the Opus in 1995, it was more than a chronograph — it was a statement of transparency, engineering, and independence. As one of the very first fully skeletonized automatic chronographs, the Opus defied convention by exposing what others concealed. Three decades later, we continue that legacy with a bold reinterpretation of the original vision. The Opus remains a technical marvel, reimagined with modern materials and fresh proportions. What began as an avant-garde breakthrough has become a modern mechanical icon.
