Roger Dubuis Excalibur Spider Huracan Sterrato MB Limited Edition

The Excalibur Spider Huracan Sterrato MB by Roger Dubuis is a Boutique Exclusive timepiece created to mark the launch of the Lamborghini Huracán Sterrato.

Limited to 28 pieces, this new creation was born from the partnership between Lamborghini, the super car manufacturer from Italy, and ROGER DUBUIS HYPERWATCH™ manufacturer from Geneva.

MB stands for Monobalancier. The Excalibur Spider Huracán Sterrato Monobalancier (MB) watch houses a self-winding mechanical caliber with a 12° tilted balance, two barrels and rotor inspired by a wheel rim.

Inspired by the automotive world, the Roger Dubuis RD630 calibre was developed specifically for the partnership with Lamborghini Squadra Corse. The twin barrel power supply offers a power reserve of 60 hours.

The movement structure is designed like a super-car engine with strut-bars forming a clear and visible visual signature. The rotor is designed like a super car wheel rim.

This automatic Excalibur Spider watch features a 45mm diameter carbon case with black DLC titanium bezel. It comes with a rubber strap with camo pattern, interchangeable with QRS – Quick Release System.
