Inspiration and design
One of the inspirations for the Montblanc Heritage Precision Chronograph collection comes from the Montblanc Pythagore watch. This watch born in 1948 has a pure and elegant ivory dial, practical Arabic numerals and precise minute scales. The thin polished gold case with curved lugs and stepped bezel highlights everywhere The essence of classic Swiss fine watchmaking. The new Montblanc Heritage Precision Chronometer Series Tourbillon Minute Chronograph is inspired by this historical piece.

Continuing the consistent precision and outstanding performance of Montblanc precision timepieces, the new Montblanc heritage precision chronograph series external tourbillon minute chronograph is equipped with the innovative MB R230 Montblanc self-made movement, and has two important precision timepiece complications: pole Legendary patented external tourbillon with stop-seconds and single-button timing system with dual barrels.
The exclusive patented complex device for the one-minute external tourbillon was completely developed by the Montblanc watchmaker and was first introduced in 2010. The word ‘Exo’ is derived from the Greek word meaning ‘outside’ or ‘outside’, which means that the screw balance is placed outside the tourbillon rotation frame. This patented innovative mechanical structure makes the rotating frame smaller in size and does not need to load the weight of the balance wheel, so it can save more than 30% of energy compared with the traditional tourbillon. At the same time, because the balance wheel is placed outside the rotating frame, it means that it can be protected from the inertia of the frame, which further improves the accuracy.
Montblanc’s self-made chronograph movement incorporates an innovative tourbillon device, and at the same time perfectly integrates all elements of traditional chronograph watches with modern high-performance structure: single-button chronograph system with column wheel device, precise and efficient vertical clutch device, 18K plating Rose gold rotor with self-winding device and a double barrel that provides approximately 50 hours of power reserve.
This movement also contains a high-performance stop-second device, which directly stops the screw balance through a miniature spring, allowing the wearer to accurately adjust the second hand. The stop-second device can immediately stop the balance wheel in the tourbillon, instead of just rotating the frame, so as to prevent the ‘back swing’ phenomenon of the balance wheel when the tourbillon frame stops and avoid affecting the accuracy. The tourbillon frame is provided with a red arrow pointer, which reads the seconds on the corresponding scale at the opening of the tourbillon dial for accurate adjustment of the second hand.

From mechanics to aesthetics
In order to pay tribute to the brand’s long-established heritage of fine watchmaking, the details of the new Montblanc heritage precision chronograph series external tourbillon minute chronograph are ingenious, especially the delicate dial covered with the carefully dyed blue aventurine. This precious semi-precious stone is a kind of quartz. It contains a small particle and has a brilliant effect like a starry sky, shining elegantly. The bottom of the dial is composed of a gorgeous external tourbillon, silver vertical satin-finished plywood and an 18K rose gold-plated bridge.
The rose gold-plated sword-shaped hands at the top and middle of the dial indicate the hours and minutes, and the intersection of the hands is decorated with an elegant blue flinqué pattern. This focus not only balances the tourbillon at the six o’clock position, but also functions as a date indicator, with the rose gold-plated hands with red arrows indicating the current date on the small dial outer scale. The chronograph function is implemented by the small dial at 8 o’clock and the minute dial at 4 o’clock. The two semi-circular chronograph dials are equipped with hands of different lengths to correspond to the corresponding sector scale to record the elapsed seconds and minute. Other fine watchmaking details include the minute dial of the outer circle of the dial, which makes time more precise and legible, and the Montblanc patented star-shaped diamond set at 12 o’clock.
The Montblanc Heritage Chronometer Precision Tourbillon Minute Chronograph is equipped with an ultra-thin round 18K rose gold case with a diameter of 44 mm. The curved lugs on the individual facets, the stepped concave bezel and the embossed crown engraved with Montblanc’s classic hexagonal white star logo all reflect the superb craftsmanship of this masterpiece of timepieces. In addition to this model, Montblanc also released a limited edition watch with 76 diamonds on the bezel, which is limited to 28 pieces worldwide.
Beyond the pinnacle
In order to guarantee the top quality and excellent performance of watches, all Montblanc heritage precision chronograph series watches have passed the extremely stringent ‘Montblanc Lab 500 hours quality test’. This quality inspection system is independently developed by Montblanc, and it performs a comprehensive quality test of the watch by simulating many situations in real life. Most watch tests are only for movements, and Montblanc’s unique 500-hour test will carry out a comprehensive test of the watch, which makes each work that passes the test more precious. Montblanc Heritage Chronograph watches are equipped with top-quality crocodile leather watches, made by the Montblanc Pelletteria leather workshop in Florence, Italy.
