Some of the quartz watches that used to be despised are actually quite advanced
May be as much as I do, I think a lot of people see more mechanical watch, quartz watch isn't worth mentioning, even someone want to recommend table, recommend basic don't speak much of quartz, unless you are a female table, girls usually afraid of mechanical watch, so prefer quartz. However, today, I want to use my limited knowledge, combine some historical data, and simply talk about quartz watches, which I think may break some people's inherent understanding of quartz watches. Quartz watches we tend to equate them with cheap watches because they are so cheap to sell, and it's not polite to say that many people have had a quartz watch as a child, some with a display screen. The cheapest watches that are now sold in the stores are mostly quartz watches, so a lot of people actually have an illusion that the quartz watch is cheap, unsophisticated and not crafty. Quartz watch is not always so, however, since the 1970 s, has been more high-end quartz watch, at the time, they cost even more than mechanical watch, now, there are also some quartz watch, they are not cheap, is also not low, but is very technical.
Speaking of quartz watches, I think we should know some basic things about quartz watches. In essence, a pointer to a quartz watch, and a mechanical watch, have a lot in common, except that the power source is different, and the other parts are not even different. They are walking display system, has the gear train, also has the oscillator, and the difference is that mechanical oscillation of the system is composed of watch-balance enhances balance spring, and quartz watch is performed by quartz vibrator. But if you know the structure of the quartz oscillator, it should be understood that it is actually a physical resonator, not a chip-type frequency manufacturing device. So, in essence, the quartz oscillator and the cycloid are a physical oscillation system. Another difference is that the mechanical watch is responsible for energy transmission and frequency interconnection between the gears, while the quartz watch is charged by the circuit board, and the stepper motor is responsible for the frequency output. Finally, the gears transmit the frequency to the pointer, indicating the time. In plain English, the same is oscillator is physical, inside has a gear, the difference is a spring, an electricity, mechanical watch with escapements output frequency, quartz to gear with the motor output.
So why is a quartz watch more accurate than a mechanical watch? After all, everyone is a physical oscillator. The reason is that the quartz quartz vibrator, which is internal crystals, can achieve the vibration frequency, far higher than that of mechanical watch, mechanical watch can achieve the vibration frequency, at present is in commonly 3 hz or 4 hz (namely 21600 VPH or 28800 VPH), while the standard quartz resonance frequency is 32768 hz, 8000-10000 times that of mechanical resonance frequency. As we all know, the higher the vibration frequency, the smaller the external influence, the higher the accuracy. So we see a mechanical watch the ideal state, the difference of 10 seconds is good, difference of 30 seconds is normal, if there is a certification, so generally can reach poor day 5 seconds. And the quartz watch, the standard error is plus or minus 15 seconds/month.
