ROGER DUBUIS IN CONJUNCTION WITH PARTNERS PIRELLI AND LAMBO- RGHINI SQUADRA CORSE, Roger Dubuis will debut two new 45mm pieces: Excalibur Aventador S (named after Lamborghini’s flagship high-performance roadster) and Excalibur Spider Pirelli (In titanium black DLC). The former model is a Lamborghini-exclusive timepiece with a choice of three Lamborghini-matched colors on the hands, markers, and the barrel cover plate. The unusual caliber is distinctive with an engine-shaped specially developed for the trademark Duotor manual-wind caliber with doubled-sprung balances. A pink gold model (pictured below) issued in a twenty-eight-piece limited edition will also be available. The Excalibur Spider Pirelli boasts Calibre 820SQ, an beautifully finished skeleton- ized automatic movement with a micro-rotor, inside a fluted titanium black DLC skeletonized bezel and a white rubber over-molded crown (which matches the white stitching on the strap). The strap itself is manufactured from winning Pirelli motorsport tire rubber and features the tire’s distinctive tread on the interior. 76 | INTERNATIONAL WATCH | WINTER 2018
