You may be familiar with a common-or-garden tourbillon, but an exotourbillon has the minimal weight of the cage disconnected from the balance wheel, making it even more precise. Aside from the science, it’s a beautiful, bold watch. It’s slim (just 9.37mm high) and, at 38mm, is substantial without being imposing.
Having its horological guts on display can make a watch look masculine, but that’s balanced out by the diamond-set bezel and guilloched mother-of-pearl dial. It also has a simple release button on the strap so it can be easily swapped. It’s certainly a surprise but one of the best ones to have come out of Montblanc for a while.
