Montblanc Collection Villeret 1858 Tourbillon Bi-Cylindrique in Platinum
This year the Swiss brand will issue a new take on the last year`s Montblanc Collection Villeret 1858 ExoTourbillon Chronographe timepiece. The new Montblanc Collection Villeret 1858 Tourbillon Bi-Cylindrique watch will feature almost the same case, but will be powered by a different movement.
The movement in question is the new hand-wound Manufacture Calibre MB M65.63.
Besides a beautifully executed tourbillon escapement that occupies the upper part of the dial (it is in fact the movement’s mainplate that serves as a dial,) the M65.63′s main point of interest is the pair of cylindrical balance-springs.
Positioned concentrically one inside the other, each spring has its own diameter, but both supply the movement with identical torque.
Expanding and contracting in an antiphase (while the first spring expands, the other one contracts,) this design ensures better isochronism thanks to a much flatter effective torque diagram.
According to the Swiss maker of expensive writing instruments, this is the first wristwatch that employs such a design. Previously it was used only in much larger maritime chronometers.
The movement is placed inside a large teardrop-shaped case about 47 mm in its longest part.
The watch’s polished bezel features a Dali-like “melting” shape with its concave profile gradually transforming into a convex curvature in its lower part. The watch indeed does look like it has survived a nuclear blast and then was lovingly restored.
Just kidding, the timepiece looks absolutely fantastic.
Montblanc plans to produce the watch in a number of limited edition versions, including one in platinum 950 (pictured,) as well as in 18-carat white and rose gold.
