Chronoswiss Opus Chronograph New Edition

Chronoswiss presents a new edition of the Opus Chronograph by unveiling two new skeleton models. These new skeleton chronograph models highlight the Lucerne based independent watch brand’s mastery in contemporary and classical skeletonising.

Chronoswiss Opus Chronograph New Edition

The mechanical clarity of the classical Opus Chronograph is achieved by dexterously paring away all superfluous material, leaving nothing but a filigreed skeleton – which functions just as well as when fully fleshed.

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, hugging the wrist more comfortably.

Chronoswiss Opus Chronograph New EditionThanks to the double anti-reflection treatment of the sapphire crystal, the skeletonising can be admired clearer than ever before. And in line with contemporary user-friendly needs and expectations, the watertightness has been upgraded to 100 metres.

In the limited edition version, the subdials showing date, chronograph hours and minutes and small seconds are blue and orange.
