Hands on with the Montblanc Timewriter II Bi-Fréquence 1000
The greatest oddity of Montblanc this year is the new Timewriter II. A half-yearly venture that brought about the Timewriter I, Metamorphosis, two years prior. This year it’s a chronograph once more, however now one that can match 1/1000th of a second.
The ‘Timewriter project’ is something Institut Minerva does together with a youthful watchmaker who doesn’t have the chance to make his own thought, since he basically doesn’t have the assets. The Timewriter II is made as a team with Bartomeu Gomila and shows another way to deal with estimating time to a precision of 1/1000th of a second.
How does it work? Let’s start with depicting how the Timewriter II Bi-Fréquence is begun and halted. In the same way as other chronographs created in the Montblanc Manufacture in Villeret, the chronograph is worked by a mono-pusher. The pusher isn’t in the crown, yet situated on the top side of the case, over the 12 o’clock position. The crown is utilized for winding and setting (when pulled out) the watch. On the off chance that the crown is turned counter-clockwise (when in the winding position), the origin for the chronograph function is being powered.
The time is shown by the focal hour and moment hand and can be perused on the little concentric Roman hour markers. The genuine accomplishment of the watch is obviously the chronograph and perusing the slipped by chronograph time has been given a lot of consideration in the design.
There are three places that monitor the recorded time, or really four. The minutes and seconds are shown on one pivot at the 6 o’clock position; the seconds are shown on the dark ring with white and red markers and the moment counter records as long as 15 minutes and can be perused from the internal white circle.
The 1/100th seconds are demonstrated by the huge red focal seconds hand and can be perused outwardly track that goes from 0 to 100. The 1/1000th seconds are shown by the red bolt in the dashboard-like presentation. When the chronograph is halted the red bolt will bounce from the N (unbiased) position to the real estimated 1/1000th of a second.
And there is one more pointer to the correct side of the dial. That is really the force hold pointer of the chronograph. On account of the mind blowing speed, this piece of the development utilizes a great deal of force and the force hold is restricted to 45 minutes (which is in reality a ton when compared to ‘the’ other chronograph that measures to 1/1000th). Since this marker gauges the force save extremely exact, it can likewise be utilized as a 45 minutes counter. On the off chance that one needs to gauge a more drawn out time than 45 minutes, it’s conceivable to wind the chronograph while it’s running.
Yesterday I got the opportunity to converse with mr. Alexander Schmiedt, Director of Watches at Montblanc, and requested that he clarify the Timewriter II Bi-Fréquence.
The name as of now shows that this watch has two adjusts, each with an alternate recurrence, henceforth Bi-Fréquence. The balance for the ‘normal time’, an old style screw offset with Philips terminal bend, has a breadth of 11,4 mm and vibrates at 18,000 semi-motions each hour (2.5 hertz). The other equilibrium is for the chronograph and has a recurrence of 360,000 (!!) semi-motions each hour (50 hertz). This is an unbelievably high recurrence and an enormous equilibrium couldn’t stay aware of this sort of speed. Therefore the chronograph balance is a lot more modest, with a measurement of 6 mm.
Now the unavoidable issue is obviously how to gauge 1/1000th of a second, while the ‘normal’ chronograph parts can match 1/100th of a second. The Spanish watchmaker Bartomeu Gomila was propelled by a cherished memory: as a kid on the island of Menorca, Bartomeu wanted to play with a major wooden band, which he would move along the sea shore either by over and again pushing it with his hand or striking it with a little stick. He before long understood that he could keep the circle abounding in a uniform turning movement in the event that he ceaselessly gave it similarly solid impulses at similarly planned intervals.
This arrangement offers huge points of interest which make it far better than each ordinary instrument that has at any point been utilized to quantify thousandths of seconds with the guide of a 500-hertz wavering body. Most importantly, a frequency of only 50 hertz creates extensively less rubbing and definitely diminishes wear. Furthermore the chronograph presently has significantly more force save and this long-enduring force save likewise adds to the routineness of the adequacy of the hundredths-of-a-second equilibrium which, thus, improves the accuracy of the time measuring.
The development itself is a piece of craftsmanship, with wonderfully planned scaffolds and just exquisite hand-wrapping up. The extensions are done with Côte de Genève and sloped and the mainplate shows pèrlage. The image above shows a delivering of what the completed development will resemble, when it’s prepared. At the SIHH we got a few active time with a completely working model and we were exceptionally intrigued by this idea of estimating time to an exactness of 1/1000th of a second.
