The iconic 45 mm skeleton Excalibur case is the centrepiece of the new rose gold version of Roger Dubuis' Diabolus in Machina. This creation sports a combination of polished and matt finishes and is distinguished by two sophisticated complications: a flying tourbillon with a minute repeater and melody repeater function indicators. Moving them is the calibre RD107, mechanical with automatic winding (558 components, frequency of 21,600 vibrations/hour and 60-hour power reserve), visible both through the dial, traversed by skeleton hands and polished indexes filled with SuperLuminova, and through the sapphire crystal opening on the back. Guaranteed water-resistant to 3 atmospheres, the Diabolus in Machina is fitted with a calfskin strap with a pink gold and titanium folding clasp.
