Launched at the Monaco F1 Grand Prix , the new 'disruptive' Excalibur Spider Pirelli Single Flying Tourbillon features the gravity-defying tourbillon in a black DLC-coated titanium case. The 28-piece limited edition features a transparent view of the new RD508SQ hand-wound calibre with a power reserve indicator and a state-of-the-art black Astral Skeleton.

The skeleton dial comes rimmed with a speedometer-like second counters with automobile-inspired pointers. The single flying tourbillon can be seen at the 7 o'clock position. The power reserve is multi-coloured offering a nod to the racing car cockpit fuel gauges. The seven straps take inspiration from seven Pirelli tyre colours, and come with a QRS (Quick Release System) on the strap and buckle.
