Pioneer In 1969, Zenith was not the first who invented the automatic chronograph.
And the creation of innovative Caliber with an operating frequency of 36 000 pc / h was something new, though not very spectacular at the time.
Nevertheless, it remains the only caliber of that era, whose speed record still not broken and has been successfully used in our days.
The reason for its large number of fluctuations is to improve the accuracy.
However, it also became one of the first challenges in the field of machinery lubrication: extreme speed of descent caused bursts of oil in areas where it was not desirable.
Such problems with the high-performance engine led to the use of special lubricants with low viscosity, which, as a rule, are not used in watchmaking for this purpose.
Watch El Primero Stratos Flyback Striking 10th completed with Caliber 4057B, operating at a frequency of 5 Hz.
It is important to note that the balance frequency is by far not the only factor affecting the accuracy of the clock.
Other elements that may affect the accuracy are the balance wheel and balance spring.
They should ideally fit the overall production system.
Needless to say, for 47 years from the Zenith mechanism of the invention has mastered every aspect of high-caliber El Primero and today it is a reliable and very precise mechanism.
New technology and materials The last 15 years have led to revolutionary changes in the production process of mechanical watches.
One of the reasons was the treatment of parts using CNC machine that can more accurately produce the individual components.
The next was the discovery of new materials ranging from nickel-phosphorous components LIGA and easy access to Mimotec technology – that suddenly allowed to create components with tolerances that are almost not felt and do not require lubrication.
This was achieved using silicon technology.
Silicon modified form of triggers and allowed to use a much higher frequency, since no wear, no lubrication is no longer a problem.
Watchmaker Martin Braun recently explained on this subject very briefly: For many years I thought about improving the standard Swiss anchor escapement in my own arrangements What I imagined was impossible to create using traditional materials and methods of production of silicon appearance in the watch.
actually it allowed me to finally realize the solution that I imagined.
In short, this was due to the angles of the Swiss anchor escapement, which, in his opinion, is a compromise between efficiency and capillary effect, which keeps the oil in place.
More about this need not worry, as the trigger mechanism consisting of silicon parts, requires no lubrication, – he said.
