Chronoswiss expands its iconic Opus family by presenting the new skeletonised Opus Chronograph Flag. Made of stainless steel, this new model sports a skeleton dial with blue, white and red highlights.
On the new model, the bridges of the Chronoswiss Calibre C.741S movement have a galvanic black finish, which provides a shadowy backdrop to the sweeping hours, minutes, seconds, date and the bright red chronograph seconds. You will also see the skeletonising clearer than ever before, as the curved sapphire crystal is now getting a double anti-reflection treatment.
Around for more than a quarter-century, the Opus architecture has been thoroughly updated. Its new geometry combines a 41-millimetre diameter with shorter lugs hugging the wrist more comfortably. Finishes include a satin-brushed case band, shiny lugs and the typical Chronoswiss markers of a knurled bezel and generous onion crown. Its water resistance has also been improved to 100 meters.
The alligator leather band is held in place with screw-in lugs featuring the Chronoswiss patented Autobloc system.
