Montblanc unveils three new models in its well-regarded Heritage Chronométrie Collection. These include two new interpretations of the patented Exo Tourbillon Slim and a contemporary expression of the perpetual calendar complication in sapphire.

The watches feature new 40-mm thin cases with new dial aesthetics. The polished cases have been completely reworked with slimmer horns to emphasize the patented Exo Tourbillon mechanism and the Perpetual calendar complication. Additionally, the distinctive dials have been redesigned with contemporary, pure lines. They come in either 3-Dimensional construction, sapphire crystal or in a skeletonized version that depicts a dazzle-camouflage pattern.

To complete the overall look, these timepieces are fitted with brand-new dark-blue-colored straps coming from the Montblanc Pelletteria in Florence. For utmost performance and precision, these three new models are certified by the Montblanc Laboratory Test 500.

The Montblanc Heritage Chronométrie Perpetual Calendar Sapphire

The perpetual calendar complication with a smoked sapphire dial and a realistic 3-Dimensional, domed view of the moon from earth. The transparency of the sapphire crystal allows a view on the movement and the functions beneath, bringing a clear technical look to the timepiece. The perpetual calendar indications are featured on transparent counters that have been crafted in a dark-blue color that matches the flange and the alligator strap. Other details include a white minute track, classic refined sword-shaped hands and rhodium-plated indexes and numerals that have been directly applied on the sapphire.

The Montblanc Heritage Chronométrie Exo Tourbillon Slim

The new Heritage Chronométrie Exo Tourbillon Slim is equipped with the Montblanc Manufacture Calibre MB 29.24 featuring the patented Exo Tourbillon, unique to Montblanc, combined with a quick stop-second mechanism. It incorporates a micro-rotor and allows an uninterrupted view on the movement through a sapphire crystal case back, in comparison to a standard rotor that always hides half of the movement. The whole construction measures a mere 4.5 mm in height.

The one-minute Exo Tourbillon complication was first introduced in 2010 and is developed entirely in-house by the master watchmakers at the Montblanc Manufacture in Villeret. The Exo in the name is derived from the Greek for external or outside and refers to the balance with its 18 screws, which is positioned outside of the tourbillon’s rotating cage. The patented mechanical architecture allows the cage to be smaller in size and free of the weight of the balance, saving more energy than a conventional tourbillon. The fact that the balance is positioned outside of the rotating cage also means that it isn’t affected by the inertia of the cage, therefore improving precision.

A new modern semi-hexagonal bridge with flat polished finishing is fixed above the tourbillon’s cage and is adorned with blued screws and surrounded by a contrasting blue minute track with white markers. Montblanc’s tribute to its fine watchmaking heritage carries through to the design of the watch with a sophisticated 3-Dimensional dial crafted in two parts. The main dial comes in a slate grey with a vertically-brushed finish, while the blue flange features a white minute track to match the overall design and increase legibility. The hours and minutes are indicated with classic sword-shaped hands, applied indexes and numerals. The Montblanc Heritage Chronométrie Exo Tourbillon Minute Chronograph comes in a new 18-karat white gold, polished, 40 mm case with a height of 8.9 mm and slim horns, further contributing to the refinement of the timepiece.


The Montblanc Heritage Chronométrie Exo Tourbillon Slim Openworked

A new one-of-a-kind skeletonized watch, the Heritage Chronométrie Exo Tourbillon Slim Openworked comes in contrasting dark grey and blue. Both sides of the movement and the dial have been skeletonized using a dazzle-camouflage design that gives a trompe l’oeil effect.

Dazzle-camouflage is a popular motif originally a design technique used in World War I to camouflage the sides of ships. The bright, cubist-style patterns were designed to confuse the enemy and make it difficult to estimate a ship’s range, speed, and direction. The geometric shapes use contrasting colors that interrupt and intersect each other and bring a unique 3-Dimensional aesthetic.

The components of the movement mirror the dazzle-camouflage design through skeletonization and different finishings. A closer look reveals wheels which have been rhodium coated and satinated, a barrel that has been skeletonized to reveal the spring, a rhodium-coated micro-rotor with a new finishing and the main plate featuring a black rhodium coating with micro-blasted and sandblasted finishings adorned with blued screws. The new Exo Tourbillon bridge with its semi-hexagonal shape and balance wheel have been coated with rhodium, completing the look with 18 screws, two of which are in gold for regulation purposes. To complete the look the bridge has been both polished and mirror polished.
