Montblanc exquisit watch novelties unveiled at Salon International de la Haute Horlogerie (SIHH) in Geneva

The exquisite watch collections, which were unveiled by Montblanc during the Salon International de la Haute Horlogerie (SIHH) the 2012 edition of which opened today are: Montblanc Nicolas Rieussec Chronograph Open Hometime, Montblanc TimeWriter II Chronographe Bi-Fréquence 1.000, Montblanc Collection Villeret 1858 – Vintage Tachydate,  Montblanc Collection Villeret 1858 Chronograph Régulateur Nautique, Montblanc TimeWalker TwinFly Chronograph GreyTech.  


Montblanc’s TimeWriter II Chronographe Bi-Fréquence 1,000

The principle of conservation of energy decrees the impossibility of ever constructing aperpetuum mobile. And in order to measure time to the nearest 1/1,000th of a second, a mechanical watch must have a balance that completes 3.6 million semi-oscillations per hour, i.e. its frequency must be 500 hertz. But such laws, it seems, are binding only in the three-dimensional world. They’re invalidated when we move into the fourth dimension: time. How else would it be possible for Montblanc to unveil at the Salon International de la Haute Horlogerie in January 2012 a wristwatch chronograph that can measure elapsed intervals to the nearest 1/1,000th of a second, yet has a balance which oscillates at a pace of only 50 hertz?

Montblanc’s master watchmakers in Villeret have achieved a remarkable feat with the The TimeWriter II which was realized by the Hispano-Swiss watchmaker Bartomeu Gomila at Montblanc’s ateliers in Villeret under the aegis of master watchmaker Demetrio Cabiddu.

The 1/1,000th of a Second at a Glance

The ordinary time of day or night is indicated by an hour-hand and a minute-hand at the center of the dial; a rotating disc of sapphire crystal collaborates with an immobile triangular index to track the continually running seconds at “9 o’clock”: both of these displays keep time accuratelythanks to a large screw balance which swings at the traditional pace of 18,000 hourly semi-oscillations (2.5 Hz) and is readily visible through the partially skeletonized dial at “7 o’clock.”

All other indicators serve the chronograph function, to which this exclusive timepiece devotes the highest priority. The chronograph’s little balance can be seen at “half past ten”: when this speed demon is switched on, it oscillates at a rate of 360,000 A/h (50 Hz). These vibrations are so fast that they can no longer be seen by an unaided eye: only a quiet purr can be heard, not unlikethe sound of a well-lubricated Singer sewing machine. The chronograph’s indicators begin witha red, centrally axial, elapsed-seconds hand: it completes one full 360° rotation every second sothat its tip sprints along the hundredths-of-a-second scale on the dial’s periphery. A doublecounter at “6 o’clock” has a longer, red-tipped hand tip to tally elapsed seconds from one to sixty, as well as shorter, all-red hand to count a maximum of fifteen elapsed minutes.

How It Works

When an elapsing interval is being measured, the chronograph’s elapsed-seconds hand (thetrotteuse) orbits the entire dial once per second. But rather than occurring as a smooth progression, this circular motion is subdivided into 100 individual steps which the naked eye cannot distinguish from one another, just as the twenty-five motionless photos that succeed each other in each second of a classical film are perceived as a seamlessly flowing motion picture. The chronograph’s center-wheel, to which the central chronograph hand is affixed, likewise jumps from one tiny step to the next in hundredth-of-a-second increments.
