Montblanc Timewalker Series External Tourbillon Minute Chronograph (Limited Edition 100)

For the first time, Montblanc’s modern urban style Timewalker series watch is equipped with Montblanc’s exclusive patented external tourbillon. This performance combines excellent time calibration components with a single-button chronograph function, incorporates a bold aesthetic design, and uses lightweight and highly durable materials to enhance the performance of Timewalker watches from the case to the movement.

The Essence of Timewalker Series
   With a large dial, a slim bezel, unique wave-shaped Arabic numerals, spear-shaped hands, and exquisite hollowed lugs, the Timewalker series creates a unique timepiece with a distinctive modern aesthetic style. This model is made of high-tech materials such as titanium, carbon fiber and diamond-like carbon (DLC), making the timepiece light and sturdy. It is also equipped with a selected automatic winding movement and a series of practical and complicated functions, highlighting the timewalker’s outstanding performance and Compact design.
External tourbillon
   Montblanc introduced the external tourbillon function to the Timewalker series for the first time in the Timewalker series external tourbillon minute chronograph (limited edition of 100 pieces). Montblanc’s patented external tourbillon device is one of the highlights of many models of the heritage chronograph series, but has never appeared in the Timewalker series before.
   The one-minute external tourbillon is exclusively developed by the watchmaker at Montblanc. The English name ‘Exo’ is derived from Greek, meaning ‘outside’, and refers to the screw balance outside the tourbillon’s rotating frame. This patented design reduces the size of the rotating frame, is not affected by the weight of the balance wheel, and saves about 30% of energy compared to an ordinary tourbillon. The balance wheel is placed outside the rotating frame, which is not affected by the inertia of the frame and improves accuracy. Another practical feature of this structure is the realization of the stop-second mechanism. The screw balance is stopped by a miniature spring, enabling the wearer to set the seconds hand accurately. This stop-second mechanism can directly stop the balance wheel instead of the tourbillon frame, preventing the ‘back swing’ phenomenon after the stop seconds, which affects the accuracy. The time setting function of this watch is very practical. The wearer can move the crown to the second position and move it back and forth, that is, the hour hand can be adjusted in hours, which is fast and easy. There is no effect on the minute and second hands when adjusting, so that the travel time is always accurate. This feature is also applicable to the date setting, making it easy to set the time on the go. The wearer can dial the hour hand forward or back in 24-hour increments to adjust the date. When the needle point sweeps past the 24th hour, the date hand will move forward or backward accordingly. Turn the crown to the third position, and you can see the red arrow pointer in the tourbillon frame for precise adjustment of the second hand.
   This bold and innovative tourbillon structure is integrated into Montblanc’s uniquely developed chronograph movement. It perfectly integrates all the elements of traditional chronograph with modern high-performance structure. It is equipped with a single button, column wheel, efficient and accurate vertical coupler, automatic winding Chain and double barrel.
   Through the titanium caseback of the Timewalker series tourbillon minute chronograph (limited edition of 100 pieces), you can see the exquisite skeleton winding rotor of the movement, decorated with the carved Montblanc logo, and the exterior is black plated Rhodium coating, more stable temperament.

Fusion of high-tech materials
   The three-piece case with a diameter of 44 mm is uniquely made of titanium, carbon fiber and diamond-like carbon (DLC). The micro-machined titanium bezel is plated with a scratch-resistant black DLC coating, and the case middle is made of a unique carbon fiber structure with a special horizontal stripe pattern instead of a common mesh pattern. Multi-layer carbon fiber coatings are stacked vertically with each other, and are fused with artificial resin in a high-pressure and high-temperature environment of ten tons to form a dense carbon fiber block. The round case of the case is pressed into the carbon fiber layer vertically to form a tight and seamless ‘single body’, which is tightly placed on the case’s titanium middleware, clamped and fixed by two hollow titanium brackets, and the surface is precision-drawn. Process. The light and sturdy case created in this way not only effectively protects the watch’s internal movement, but also reflects the unique style of the Timewalker series.
Delicate dial design
   Montblanc TimeWalker Series Tourbillon Minute Chronograph (limited edition of 100 pieces) with grained dial design, perfectly blending beauty, function and legibility. The eccentric black dial at 12 o’clock shows the time, with red and white Arabic Digital scale with super-luminous SuperLumiNova® * coating for easy time reading at night; patented external tourbillon device can be seen in the lower part of the dial, with two semi-circular chronograph dials with double hands: seconds counter at 8 o’clock Position, the minute counter is at 4 o’clock. The upper half of the dial is decorated with black horizontal stripes, and the lower half has a vertical matte effect, highlighting the patented external tourbillon device. The dial is also decorated with a domed sapphire crystal, which is anti-reflective on both sides and has vertical wings. It has excellent readability and anti-scratch performance.
   The black alligator strap with red stitching further highlights the urban style of this watch. All 100 watches in this limited series have undergone a full 500 hours of rigorous real-life simulation tests and have been awarded the ‘Montblanc Lab 500 Hour Quality Test’ certification.
