Description
Around for 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.

The mechanical clarity of the Opus Chronograph is achieved by carefully paring away all superfluous material, leaving nothing but a filigreed skeleton. The dial may be scarcely there after the careful and ingenious skeletonising process – but nevertheless the blue and silver subdial perimeters make a great impression.
