The skeletonized dial and movement of the elegant chronograph reveal deep insight into the fascinating world of a perfect mechanical watch.
Opus Chronograph
The 2020 version of the exceptionally complex 300-part masterpiece Opus Chronograph – which in 1995 advanced the skeletonising chapter at Chronoswiss – has been thoroughly updated. It now offers a modern geometry with a 41-millimetre case and shorter lugs.

Movement
C.741S
At the core of the Opus Chronograph 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
Stainless Steel
Chronoswiss relies on stainless steel for its durability and sheen. With excellent resistance to corrosion and scratches, stainless steel provides a perfect balance between longevity and aesthetics. Chronoswiss primarily uses high-quality stainless steel in its watches, ensuring everyday practicality along with timeless elegance.
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.
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.
