Montblanc Heritage Chronométrie ExoTourbillon Minute Chronograph


Another horological highlight of the Montblanc Heritage Chronométrie Collection, this timepiece combines two of the most important chronometric complications: a chronograph and a revolutionary tourbillon. The Montblanc Heritage Chronométrie ExoTourbillon Minute Chronograph takes performance to exhilarating new heights.

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 Calibre MB R230 features as a second complication: a monopusher chronograph with a vertical clutch, a column wheel and a double barrel.

The sophisticated dial with different levels and refined finishes reflects the two complications of the timepiece. The upper dial, embellished with a fine ivory-grainé texture, is reserved for the date, hours and minutes and the chronograph indications with its lacquered counters. The lower level with vertical satin finishes unveils the intricate construction of the ExoTourbillon at 6 o’clock.


The dial is encased in a 44 mm case made of 18 K red gold with a concave bezel for scratch pro-tection and imposing round horns with distinctive facets. The otherwise fully polished case contrasts beautifully with the satin-finished decoration between the horns.
