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.
The skeletonized dial and movement of the elegant chronograph reveal deep insight into the fascinating world of a perfect mechanical watch.
