A relatively newcomer on the market, Roger Dubuis was founded in 1999. Since its inception, the watchmaker has developed twenty-eight of its own mechanical calibres and seven thousand references. Nevertheless, production is far from prolific as with the more technically complicated models, Roger Dubuis is careful to limit production to twenty-eight editions so as to ensure exclusivity. This limited edition Golden Square Tourbillon is no such exception and it encapsulates avant-garde design with its unique square shape. Beneath its exceptional style, beats a heart of precision embodied in the visible flying tourbillon regulator.
