Can the Grand Seiko Spring Drive become the most accurate mechanical watch movement ever? Discover the secret behind the operator who makes Spring's sophisticated Grand Seiko movement so smooth.
Most watch enthusiasts, watchmakers, watch collectors, etc. tend to cherish and appreciate mechanical movements. What I have always heard is that making mechanical watch movements requires more brains. They are not only wonderful works of exquisite craftsmanship, but also mechanical miracles that can attract even the smartest intellectuals. There is a mysterious mystery behind the way they work, and so is the talent needed to create them. Someone will naturally ask such a question: "Why does Seiko use quartz crystals in the spring drive mechanism of a mechanical movement?"
That said, it is not surprising that this battery-powered quartz movement is usually very cheap and usually mass-produced, and will not bring the same appreciation for most luxury watch enthusiasts. So, what is the Grand Seiko Spring Drive that makes everyone enthusiastic? replica Breitling Professional Watches
To understand the fanaticism, we first need to understand the reason for introducing quartz crystals to watch the movement. There are obvious benefits to using quartz. That is, they oscillate steadily at an incredibly high frequency of 32,786 Hz, which is 215. The simple mathematical operation of its working principle is accomplished by continuously dividing the beat into two halves (providing a stable interval of one second).
This provides unparalleled accuracy compared to mechanical movement. The fact is that even the most accurate mechanical watch cannot be compared with quartz in terms of accuracy and reliability.
What makes the Grand Seiko Spring Drive different from the Quartz movement?
A traditional quartz powered watch has a battery that emits an electric charge that causes the quartz crystal to vibrate at a frequency of 32,786 Hz. This results in an accuracy of +/- 15 seconds every 30 days. This means that the accuracy deviation allowed per month is 15 seconds slower or 15 seconds faster. Of course, this is to keep your watch within the normal temperature range of 41 degrees Fahrenheit to 95 degrees Fahrenheit.replica swiss watches
In the Grand Seiko movement with Spring Drive, the frequency rate of quartz allows the second hand to sweep so smoothly. You will stare at it endlessly. Use the button below to quickly understand what I'm talking about.
How accurate is the Grand Seiko Spring Drive? The accuracy of the Grand Seiko Spring Drive is +/- 1 second per day, which is twice the precision of the best Rolex chronometer, more accurate than the METAS certified perpetual calendar, and many times higher than the COSC certified astronomical accuracy.
What Seiko does is nothing more than genius. They combined the precision of quartz with the ingenuity of traditional mechanical watches. They designed a system that allows a purely mechanical watch movement to use the stability and oscillation frequency of the quartz crystal, allowing it to use a small mechanically generated current to power the movement, while always adjusting it through the built-in circuit. Without using batteries.Best replica watches
How does Grand Seiko Spring Drive work? The current generated by the tension released by the mainspring of the watch is very small, not the battery used in the conventional quartz movement. This charge activates the high oscillation rate of the crystal. Most mechanical movements use VpH to measure the beat of the movement, which means vibration per hour, but the frequency of quartz is very high, measured in Hz (hertz), which is the number of revolutions per second.
How much vibration (VpH) does the quartz crystal vibrate per hour?
For example, high-beat mechanical movements such as Zenith El Primero have a frequency of 36,000 VpH (vibrations per hour) or 5 Hz, while the 32,786 Hz frequency of a quartz movement resonates at a rate of 32,786 vibrations per second. . Converted to 118,029,599.999 VpH or vibration per hour.replica Bell & Ross BR 05 watches
This integrated circuit or IC can handle the constant distribution of crystal high pulses, and all of this can be done without using a single battery. In turn, this triggers the stepper motor to move the second hand in increments of the second.
So, what is it to adjust the driving force of the gear? Some people would think that with such a high frequency rate, things might get out of control. The magic that keeps the spring driver so precise and stable lies in the IC and the sliding wheel.
The integrated circuit looks at the speed of the driving force behind a mechanical gear called a pulley and compares it with an oscillator. If it is found that the sliding wheel is spinning too fast, an electromagnetic brake will be applied to maintain the sliding state. It can be said that this is an intelligent braking mechanism or cruise control system. I will tell you; Grand Seiko and their Spring Drive are really another matter! replica Patek Philippe Grand Complications Watches
