Roger Dubuis first shared with us their collaboration with famed tyre-maker Pirelli in January during the 2017 Salon International de la Haute Horlogerie. The first product offerings arising from this partnership were Excalibur models, specifically the sporty openworked Spider case design.
There was a double tourbillon — the famed twin rotating escapements of the brand — and a time-only automatic, with the micro-rotor that features in so many Roger Dubuis movements. These pieces were paired with straps made partially of rubber taken from race-winning Pirelli tyres, and bright blue accents on the crown, dial-crystal gasket, dial flange, barrel bridge and hands.
Now, I know zero things about cars and motorsports in general, but I asked Google and it told me that Pirelli tyres are colour coded and blue specifically identifies its range of Formula 1 tyres that are specifically for wet weather. That blue should be the colour chosen to distinguish the first Roger Dubuis Pirelli watches is entirely appropriate to me, since the Excalibur Spider represents the same kind of powerful yet stripped-down engineering principles that go hand-in-hand with high-performance racing tyres.
