Montblanc celebrates their latest creation, the radical and impressive Montblanc Villeret Timwriter II Bi-Frequence with all the members of PuristSPro with a special contest and prize, exclusively for the PuristSPro community!  
CONTEST: Montblanc Villeret TimeWriter II Bi-Frequence 1000



Following the Metamorphosis, this is the second TimeWriter project.  The Montblanc Timewriter project is a bi-annual project hosted by Montblanc Villeret with groundbreaking independent watchmakers.  
This latest TimeWriter, TimeWriter II was conceived by Montblanc Minerva Villeret long-time head-watchmaker Mr. Dimitri Cabbidu in conjunction with the young (33 year old), WOSTEP-certified, Spanish-Swiss watchmaker Mr. Bartomeu Gomila.  The development for this piece started in at least 2007 if not prior, five years ago. 

This TimeWriter II project is cumulative of over 5 years of research, thousands of man-hours, and over 20 patents! 

The watch features a genuinely unique system.  True to its Minerva heritage of making some of the best and most unique chronographs in the world, the TimeWriter II Bi-Frequence ups the ante again with a chronograph system that accurately measures down to the 1/1000th of a second.  It achieves this by employing two balance wheels; (1) a large 18,000 bph balance for the time keeping functions of the watch and (2) a smaller diameter 360,000 bph balance wheel with a 10x wheel gear.  For more information, please watch this video. 



Truly an epic timepiece, featuring groundbreaking pioneering technology and one that is certainly the most interesting among chronographs, from Montblanc Minerva, the firm that is historically renowned for Chronographs.

There are 2 balances in the Bi-Fréquence (as the name states is has 2 frequencies)

1) one balance for the time indication, that has 2,5 Hz (18.000 bph) à (this is the first frequency)
2) A second Balance for the chronograph (short time measurement) that has 50 Hz (360.000 bph) à (this is the second frequency)
Theoretically speaking, 360,000 bph cannot measure 1/1000 sec. – they can measure only 1/100 sec. (for 1/1000th you would normally need 500 Hz instead of only 50Hz)
S With 360,000 bph it is possible to measure 1/100 sec, meaning make the chronograph second hand "jump" 100 times per second with the "normal" gear train.
In order to measure 1/1000 sec, we had to come up with the idea of how to make 10 jumps between those 1/100 seconds (Dividing 1/100 by 10=1/1000th).  The theory is simple.  As you can see in the schematic, there is an additional gear that divides one second (one round of the chronograph second hand) by 10.

Please note the contest will end October 19th at 12 midnight PST.
