Roger Dubuis Excalibur Spider Pirelli Automatic Skeleton reference RDDBEX0826.

The Excalibur Spider Pirelli is the result of a partnership between the revolutionary Roger Dubuis and iconic Italian tire manufacturer Pirelli.  Both companies share the pursuit of performance. The watch is a tribute to the pit team behind the scenes whose skills are as essential as the drivers.


It has a robust 45mm DLC-coated titanium case that houses the watchmaker’s signature skeleton dial and calibre 820SQ automatic movement, and an exhibition case back that means it can be appreciated from either side. The calibre beats at 28,800bph and offers 60 hours of power reserve.

The strap is embossed with a tread pattern on the inside and made with rubber inlays from real Pirelli tires that have raced in some of the most prestigious competitions.

Dual-layer flanges on the Excalibur Spider Pirelli show the minute track below and the hour markers on top. The latter, along with the skeleton hands receive a coat of Super-LumiNova for low-light visibility. Finally, running the show is Roger Dubuis’ Poinçon de Genève-certified RD820SQ automatic caliber with a 60-hour power reserve.
