ontinuing on a journey to create hyper expressive and contemporary masterpieces, Roger Dubuis introduces the Excalibur Hypebeast Monobalancier (MB).

Hypebeast has been invited by the Maison to join forces to co-create the latest interpretation of the iconic Excalibur Monobalancier. Now Roger Dubuis unveils the results of this collaboration with a limited edition of the Excalibur MB. Keeping the shape of its signature star unchanged, the Maison chose to coat it in navy blue – one of Hypebeast’s distinctive colours – and apply the same signature colour to the flange and around the micro-rotor as well.

To create a playful contrast that highlights these striking navy blue elements, the new Excalibur Hypebeast MB is housed in a 42 mm case in radiant white ceramic, with a white strap. This minimalist and contemporary choice further enhances the expressive clean cut lines of the original Excalibur MB, accentuating the impressive mechanical heart of the masterpiece.

Though ceramic is used throughout the horological world already, Roger Dubuis’ ceramic timepieces stand out with a display of true prowess for a key reason: a refusal to compromise on the Maison’s signature shape. This is unheard of within watchmaking, with any ceramic cases usually designed to fit to the material.

Taking ceramic from raw form to the distinctive Roger Dubuis’ case demanded remarkable talent, with the transformation taking 15 times longer than crafting the same case from gold. Only the boldest, most dedicated and skilled dare take on such a task. Hyper-resistant to daily scratches and refusing to tarnish over time, Roger Dubuis’ radiant white ceramic timepiece is where hyper durability meets hyper expressivity in a single masterpiece.

Recently enhanced with a series of mechanical and aesthetic improvements, the calibre of the Excalibur Hypebeast MB is a feat of horological prowess. With ingenuity and unmatched craftsmanship, Roger Dubuis’ engineers increased the power reserve of the automatic RD720SQ to 72 hours, as well as optimised the micro-rotor to minimise its vibrations.

Continuously seeking solutions to reach hyper performance, the balance wheel inertia is also doubled to improve stability and make it less sensitive to shocks. In the same way, better resistance over time as well as better efficiency and energy transmission are achieved by using a new lube and by optimising the shape of the escapement wheel paired with adjustable pallet-stones – both constructed from diamond-coated silicon.

Hand-finished with meticulous care, the new masterpiece is certified by the Poinçon de Genève, one of the most demanding certifications in fine watchmaking. The Excalibur Hypebeast MB is completed with a white 3D embossed calf leather strap with Quick Release System for ultimate versatility.

Offering cutting-edge trend-setters the most exciting way to experience Hyper Horology™, the new masterpiece curated by Hypebeast is limited to 28 pieces only.
