Part of Cartier’s impressive line-up of timepieces for SIHH 2017 is the Rotonde de Cartier Minute Repeater Mysterious Double Tourbillon. The intrigue for this watch comes from what’s inside the 45mm titanium case, this one of Cartier’s famous “mystery” watches featuring a minute repeater and tourbillon escapement with a totally exposed movement. By combing the mystery hour complication and minute repeater function, this becomes one of the most complicated watches to emerge from the house of Cartier.
The mystery hour is, of course, a Cartier specialty, but here the suspended hands are replaced by a seemingly magic tourbillon. However, it is the patented double-axis rotation which makes this watch a double tourbillon. The flying tourbillon cage rotates every minute and does a lap around the sapphire disk every five minutes.
The watch’s new minute repeater also takes into account the quality of sound and uses square section gongs and hammers visible on the dial side of the watch to achieve the best sound. The minute repeater can be activated on-demand at the push of a button.
This watch employs the manually wound Cartier Caliber 9407MC movement which comprises 448 components, 45 jewels, features black rhodium finishes, and is Poinçon de Genève certified. Prices will be made public when the watch is officially revealed at SIHH in January.
