In the latest 2019 iteration of this feat, Roger Dubuis goes back to the future by revisiting two specialities – the Minute Repeater and the Flying Tourbillon – housed in a carbon case with carbon bezel and flange – and firmly positioned in the hallowed universe of Grandes Complications. Coupled with a flying tourbillon and wound by two micro rotors, the Excalibur Spider Unique Series now offers an outstanding 47 mm example of contemporary and expressive Haute Horlogerie.

Invented in the 18th century to enable people to tell the time in the dark, the Minute Repeater is one of the most sophisticated watchmaking complications. Its mechanism consists in striking the time on demand when pushing a button or pulling up a slide bolt. In its most sophisticated form, the Minute Repeater strikes the hours, quarters and minutes and is generally composed of two chimes, one deep for the hours, one high-pitched for the minutes. Quarters are indicated by the succession of the two chimes: high-pitched and deep. One of the first calibres launched by the brand back in 1997, the Minute Repeater was also the first to be used to launch the Excalibur collection in 2005.
