Montblanc Villeret 1858 ExoTourbillon Chronographe
One of five variations, this particular timepiece is the first to unite two of watchmaking’s most admired horological complications: the tourbillon and chronograph functions. Its ExoTourbillon name comes from the tourbillon having a balance larger than the cage — thus oscillating outside of said cage on a higher plane and with greater precision. This equates to 30 percent energy savings, which are then used to power the chronograph’s functions. Aside from the hand-guilloched solid gold dial, what also distinguishes this series of timepieces is the hunter-style caseback reminiscent of vintage pocket watches. On the actual mechanism, meanwhile, is engraved the word Minerva, a respectful homage to the esteemed factory that now houses Montblanc’s Villeret facility — the only manufacturer in the world to produce all its parts (including balance springs) in-house.
