A one-off skeletonized marvel combining a minute repeater and a flying tourbillon in one hi-tech package. 
Roger Dubuis Excalibur Spider Unique Series
There’s hardly a better way of combining traditional haute horlogerie with hi-tech vibe than mixing classical complications and modern materials. How about a minute repeater and a flying tourbillon in a case made of carbon fiber and titanium? And what if the whole movement would be skeletonized? The one-off piece from the Roger Dubuis Excalibur Spider Unique Series offers just that, while preserving all the trademark DNA and aesthetics including the star-like bridges, tons of gleaming lume and huge 47-mm sizing. Its black and green coloring as well as the decision to release such a 558-part monster-movement watch on a black rubber strap somehow sets it apart from the majority of the current market’s options.
The in-house automatic caliber RD107 offers 72 hours of power reserve and is wound via not one but two micro-rotors
The in-house automatic caliber RD107 beating at 3 Hz offers 72 hours of power reserve and is wound via not one but two micro-rotors. Despite flowing some futuristic design codes, it is finished according to all Poinçon de Genève standards. With just one unique piece produced the Excalibur Spider Unique Series is likely more of a statement: who else can make a two-hander packed with so much tech and fun? And in this regard, it’s hard not to give the guys at Roger Dubuis some extra credit.
