The new Excalibur Spider Pirelli Sottozero from Roger Dubuis represents the ultimate performance with a touch of extreme. Extreme temperatures and conditions, to be exact.
47mm, white ceramic bezel with blue markings offsets the titanium and sapphire crystal case, the Excalibur Spider Pirelli Sottozero, proffers an incredible view of the new RD105SQ hand-wound calibre, signature blue Astral Skeleton and multi-coloured power reserve indicator representing a cool nod to racing-car cockpit fuel gauges. Speedometer-like seconds counters enhanced with automobile-inspired pointers rim the emblematic flying tourbillons at 5 and 7 o’clock respectively.
Like its predecessors, this distinctive strap features rubber inlays from certified Pirelli tyres and an interior reproducing the profile of a Pirelli Cinturato™ intermediate tyre; but this time it is also adorned on top with legendary tread motifs reproducing the profile of the best in class Pirelli Sottozero™ tyre. Characterised by this elegant tread pattern with an asymmetric design, it is set with dozens of titanium studs emulating the nails in its namesake designed for better grip under icy conditions.
