Roger Dubuis‘ offerings for SIHH 2017 stuck to its bestselling Excalibur line, with improvements in materials and colours, and also a mystifying tie-up with tyre-maker Pirelli.
With a skeletonised case that’s characteristic of the Excalibur Spider, the Pirelli editions comprise a double tourbillon as well as automatic skeleton, both with black diamond-like carbon (DLC) coated cases with blue rubber accents on the movement, chapter ring and crown. In fact, the flanks of the open-worked case reveal the blue vulcanised rubber coating on the inner case that holds the movement.
