SIHH 2010: Montblanc Collection Villeret 1858 ExoTourbillon Chronographe

The gorgeous Montblanc ExoTourbillon Chronographe (ref. 106164), the latest watch from Montblanc from the bunch that was presented last month that I want to write about, belongs to the same ultra-luxury Collection Villeret 1858 as the gorgeous Vintage Chronographe.

Presented last month at the SIHH 2010 show, the new Montblanc ExoTourbillon Chronographe (ref. 106164) watch offers Montblanc’s own take on the well-known tourbillon escapement complication. As the name implies, the tourbillon module features a unique design with its tourbillon cage separated from the balance spring and hovering gracefully just atop of the nicely decorated black dial.

Besides the obvious visual difference from the “ordinary” tourbillon watches, this kind of design also allows watchmakers from Institut Minerva to make the tourbillon cage significantly smaller, thus reducing its mass and increasing the timekeeper’s energy efficiency by some 30 percent.

Although Montblanc ExoTourbillon Chronographe‘s dial layout looks deceptively simple, it is also quite an unusual piece of work.

The “main” subdial at 6 o’clock that features two similarly shaped hands in fact serves to display time in two different time zones: white gold hand shows current time and the heat-blued hand shows time in another time zone. Since the dial features only twelve Roman numerals, there is also a smaller subdial at 4 o’clock that tells whether it is day or night in the other part of the globe (well, to my taste, a simple AM/PM indicator would certainly do the job a lot better.) So, the watch is in fact a regulateur with a twist.

Two other subdials located at 3 and 9 o’clock are a 30-minute totalizer for the watch’s monopusher chronograph complication and a small seconds counter.

The Calibre 16.60 hand-wound movement is hidden inside a pretty impressive 47 mm case, which is available either in red or white gold. Of course, the gargantuan proportions of the precious body make it almost impossible to wear if you are not a Hollywood star or an East European oligarch, but I have an impression that the watch even isn’t supposed to be actually worn on a wrist of a mortal (or, at least, not worn on a regular basis): being the Swiss brand’s tour de force, this is a work of art that is supposed most of its time inside a well-guarded safe or, later, under a bullet-proof glass of some museum.

Well, I must say that I really like this watch.
