Montblanc Villeret 1858 Tourbillon Bi-Cylindrique 106494

Tourbillon Bi-Cylindrique : 106494

The Montblanc Villeret 1858 Tourbillon Bi-Cylindrique, reference number MB106494, was released in 2011. This model features a striking 47.0 mm white gold case with a transparent caseback, allowing a clear view of its intricate mechanics. At its heart is the hand-wound caliber MB M65.63, notable for its double cylindrical balance springs—a world-first in wristwatch design—originally conceived for 18th-century marine chronometers. The watch’s dial design includes a unique bulge at the 6:00 position, which houses the 'mysterious' hours and minutes display. This combination of historical innovation and modern engineering results in exceptional precision due to the opposing respiration of the balance springs, optimizing isochronism. The overall style of the watch is both classic and avant-garde, making it a distinctive piece within Montblanc's Villeret 1858 collection.
