Excalibur Monobalancier (MB) in fashionable metal.

Designers are drawn to titanium because of its tone, anti-magnetic and hypoallergenic properties, and lightness, yet working with titanium is fraught with a whole host of challenges. All of them have to do with how labor-intensive it is to finish this metal.

Nevertheless, Titanium Grade 5 is used all over the Excalibur Monobalancier (MB) Titanium edition: for its 42-mm case, 24-tooth bezel, winding crown and caseback. The latter surrounds sapphire crystal with an anti-reflective coating and the case is water resistant up to 100 meters. 

The dial is shaped by the architecture of the skeletonized RD720SQ caliber, certified with the Poinçon de Genève (Hallmark of Geneva). A number of zones are delineated by the five arms of a star, the openworked balance and micro-rotor. Fans of the brand should already be quite familiar with this automatic movement.

The brand's designers have made some of the movement's details glow in the dark by coating triangular indentations or notches in Super-LumiNova, while other elements have received a black NAC coating to blend with the tone of the case.

The movement has taken on a silver tone for the titanium edition that runs right down to the case and bracelet. Roger Dubuis is a brand that has partnered with Pirelli and Lamborghini Squadra Corse in the past and prefers to equip its models with rubber straps to match their sporty style.

The Excalibur Monobalancier (MB) Titanium is an exception in this regard, where the watchmaker has opted for a titanium bracelet with brushed matte links and polished corners.

They've gone for the same design used for the links on last model created with Hajime Sorayama, but the bracelet looks totally different with a matte finish (the Roger Dubuis Excalibur Sorayama Monobalancier had mirror-polished surfaces, like the Japanese artist's sculpted "Sexy Robot" series).
