Among the new models unveiled at the SIHH 2016 to celebrate its 110th anniversary, this 100-piece limited series has asserted itself as the new flagship model in the TimeWalker line. Immediately saluted by connoisseurs of Fine Watchmaking and design, this technically and aesthetically innovative timepiece also appealed to members of the Grand Prix d’Horlogerie de Genève jury which selected it in the Sports watch category. How indeed could one resist the appeal of this monopusher chronograph equipped with a tourbillon whose whose balance is positioned outside (hence the ‘exo’ part of its name) the rotating cage, and whose sophisticated case combines lightweight and robust high-tech materials ?

While the patented ExoTourbillon mechanism is nothing new in itself for Montblanc, which already uses it to equip its classic line, this is the first time the Maison has applied it to the Time- Walker collection. Its two patents relate to the construction of the tourbillon (of which the cage is separate from the balance) which was entirely developed by the Montblanc teams. Released from the weight of the balance, the tourbillon cage operates with one-third less energy, while delivering enhanced precision. The performance of this mechanism is reflected in its stop-seconds function, which halts the screw-adjusted balance in order to precisely adjust the seconds that are indicated by a red arrow on the tourbillon cage. The time is adjusted by turning the crown in its third position, along with the date displayed in the center of the offset hours dial, in both directions (advancing and retreating the hours hand in 24-hour increments for the date). The twin- barrel self-winding Manufacture movement visible through the sapphire back of the titanium case is distinguished by its chronograph with column wheel and vertical clutch, synonymous with efficiency and precision. Its dark rhodium-coated openworked rotor bears the stylized six-pointed Montblanc star with rounded edges. The chromatic and geometrical contrasts elegantly continue on the front with the red-rimmed black DLC-coating of the beadblasted titanium bezel, topping the carbon fiber case middle bearing horizontal stripes. The latter are picked up on the outer dial and the notched crown. So as to guarantee legibility in all circumstances, the white and red numerals are enhanced with Super-LumiNova. Since reliability is no vain word at Montblanc, each TimeWalker ExoTourbillon Minute Chronograph is subjected to 500 hours of laboratory testing before being strapped to the wrist of its lucky purchaser.
