Product Details

At the turn of the century, a precisely calculated route was the key to great maritime triumphs, such as winning the Blue Riband for the fastest crossing of the Atlantic Ocean. As their accuracy was of vital importance, the finest marine chronometers used a cylindrical hairspring – which also drives the one-minute tourbillon of this spectacular Montblanc pocket watch. A cylindrical hairspring’s turns are wound on top of one another, ensuring the absolute regularity of the watch’s rate. Made of 281 handcrafted components, the Montblanc Caliber MB M68.40 impresses with its triple time zone indication. With hometime displayed on a delicate “rose de vents” at 12 o’clock and central local time, it is the worldtime indication that dominates the dial. To show the course of day and night around the world, two discs with 24 time zones simultaneously revolve around two fixed, three-dimensional globes. As a reference, 24 cities from each hemisphere encircle the dial. Groundbreaking innovation and fine watchmaking heritage are united on the dial and the 18 K white gold case decorated with black “Grand Feu” enamel. The spheres are carefully engraved and painted with dedicated handcraft. The slightly curved tourbillon bridge is beveled by hand. A hand-engraved maritime wave pattern adorns the upper part of the dial and the entire back of the movement. The epitome of ultimate precision and traditional artisanship, this masterpiece is limited to 8 pieces.
