Montblanc Heritage Chronométrie Exo Tourbillon Minute Chronograph
Description
The Montblanc Heritage Chronométrie Exo Tourbillon combines two of the most important chronometric complications: a chronograph and a revolutionary tourbillon with a stop-seconds mechanism. As the Greek prefix “exo” hints, its balance has been separated from the rotating cage. No longer adversely affected by the inertia of the cage, the balance wheel oscillates with greater isochronism. Developed and crafted entirely in house, the Manufacture Caliber MB R230 features a second complication: a monopusher chronograph with a vertical clutch, a column wheel and a double barrel.
