Kinetic energy is different from standard synchronous motion. It is the unique movement name of Seiko Company, which can generate electricity by itself. It uses the simple movement of the wearer's arm to generate and store electric energy, thus making the watch run. Standard quartz watches cannot generate electricity by themselves.
Power watches are as accurate as standard quartz watches. Power watches are as accurate as standard quartz watches. The "movement" is the internal engine that provides power for the watch. ) The synchronous oscillator receives the charge from the integrated circuit. The electric timer vibrates 32,768 times per second, which is why it is extremely accurate. Compared with standard quartz watches, Kinetic watches have the advantage that Kinetic represents the latest technology and the most advanced energy generation and storage technology available for watches. Compared with standard timely technology, it has the following advantages: one of the main advantages of kinetic energy technology is environmental protection. Power watches use clean and natural energy-the movement of the wearer's arm-to generate electricity. Therefore, the pollution of quartz watch caused by battery replacement is abandoned. Moreover, Kinetic is the only technology that provides its own power. For example, the solar energy meter, also produced by Seiko, uses another old technology: relying on external energy sources-sunlight or artificial light sources-to provide energy for the meter. Without an external light source, solar meters can't work. On the other hand, the kinetic energy meter can run on its own independent energy, whether it is cloudy, rainy or sunny. "
Kinetic is another engineering innovation after 1969 launched the world's first quartz watch Astron 35SQ on February 25th.
In fact, what Seiko did was to put a miniature power device into the watch. Kinetic energy captures the natural energy generated by the wearer's arm movement, then amplifies and stores it, and finally drives the timing device. This is the victory of miniaturization technology. Kinetic project has brought more than 50 patents to Seiko.
The core of the power system is located in the rotor. This little thing with a diameter of 2.66 mm and a thickness of 0.4 mm (rotor, technically a micro rotor of samarium and cobalt) can rotate at an amazing speed: 65,438+00,000 to 65,438+000,000 times per minute, and the engine of the racing car is five times faster. The movement of the wearer's arm swings the pendulum. The gear sequence transfers energy to the rotor, and when the rotor rotates, a voltage is generated between the coil components, thereby generating a current. Electrical energy is stored in another small component, ESU (Electrical Storage Unit), and released to provide power for the watch when needed. When the watch is not worn, the power of ESU can still supply power. (For details, please refer to the description of the working principle of kinetic energy movement in "Decomposition Diagram of Kinetic Energy Movement").
This is Seiko's own technology. It was developed by Seiko Epson, a major watch manufacturer under Seiko Group, Japan's largest watch manufacturing group. Seiko introduced the first watch with this technology at 1988. The name Kinetic is used in 1992. Seiko engineers found that the biggest trouble with quartz watches came from batteries. When the battery is exhausted, the watch will suddenly stop running, which is very annoying. Therefore, as early as 1982, Seiko Epson set up a special group to study the energy development instead of quartz watches. They spent six years dealing with various problems: how to protect the rotor from vibration, how to store electricity, how to stabilize voltage and so on. , making the automatic power generation system more and more perfect. In the first Kinetic watch, there is a movement called 7M, which can run for 75 hours or three days without wrist. Since then, Seiko has devoted itself to continuously improving kinetic energy technology on the basis of 7M, and introduced 5M, 3M, 1M, 9T and so on. Kinetic has been developing in the direction of less movement, more power generation and longer running time.
When we take the watch off our wrists and put it on the dresser or drawer, the pendulum will stop swinging and no electricity will be generated. The watch will continue to work with the power in the ESU until the power runs out.
The charging method is simple: gently and appropriately shake the watch back and forth. When you shake your watch, the pendulum will turn and sometimes make a slight noise. When the second hand starts to jump every second, the watch has accumulated energy for three hours, and it can be adjusted and worn at this time. A normal swing arm can gradually charge the watch. If you wear it often, you don't need to charge it, because it will charge automatically.
In the off-wrist state, Kinetic watches have different models and different running times. After Wally, the standard precision watch can run for 6 months. Sportura kinetic energy chronograph (9T82) introduced by Seiko several years ago consumes a lot of energy. Even so, it can run on a full charge 1 month. The new Kinetic chronograph (7L22) can run for 5 months, but the Kinetic Auto Relay watch can still display the time for 4 years after leaving the wrist. Kinetic automatic relay watch adopts a patented technology called "power saving function", which can make the watch in "sleep state" to save energy. If the watch is not used for 72 hours or 24 hours for a long time (for different movements), it will automatically switch to the "energy saving" state to reduce energy consumption.
In the energy-saving state, the pointer will stop turning and the timing will be replaced by an internal circuit. If the watch stops after being fully charged, the circuit can last for up to 4 years. At any time during this period, as long as you take out your watch and shake it once or twice, it will "wake up". The shaking triggers the time relay function, and the chronograph "brain" in the watch that has not stopped working for a moment will automatically transfer time to the hands of the watch, and the hands will be activated again. Hence the name "automatic relay". The hour hand and minute hand will be driven by stepping motors until they point to the correct time at that time. The needle will be driven by another motor to accomplish the same action. The watch can distinguish between morning time and afternoon time, so even after years of "deep sleep", it can still return to the accurate current time. The date needs to be adjusted manually.
Smart timecontrolled watches also have a "manual energy saving" system. Users can start the "power saving function" at any time, without waiting for 72 hours or 24 hours (for different movements), so that the watch will automatically turn into the energy saving state. Users can easily start the "manual energy saving" system by pulling the crown out of the normal position, and the watch will immediately turn to "sleep state".
The car tachometer can store electric energy for a long time, and the key is that it can make the pointer "sleep". In fact, the energy consumption of the timing device in the power watch only accounts for 15% of the total energy consumption, while the other 85% is used to drive the hands. By inventing the method of letting the watch hand sleep while the internal circuit can continue to time, Seiko engineers eliminated the energy consumed by the watch hand, which is the largest energy source (energy storage unit) of ESU. In this way, the watch can completely use all the energy for timing, and the timing function can run for a long time. The introduction of Seiko manual electronic watch marks a great leap in kinetic energy technology. 1998 Seiko's manual electric watch movement 9T82 can generate three times more power than the previous manual electric watch, making it possible for manual electric watches. 9T82 movement can drive four timing hands and three real-time hands. Seiko launched the first manual electric watch in 1999, and only 1000 watches were produced. It has a novel and unique appearance, and there are four independent sub-dials on a large dial simulating a dashboard. The real-time dial has three hands (hours, minutes and seconds). Around the dial are three other subordinate stopwatch disks: one records hours and minutes, and the longest one is 12 hours; One recording second; A record is110 seconds. Since it has ***7 hands distributed on four different dials, we can say that the power generation function of 9T82 movement is extraordinary. Even if the stopwatch function is used for 3 hours every day, a fully charged manual electronic watch can be used for a whole month without charging.
The conventional production of manual electric energy chronograph began in 2000. Subsequently, Seiko introduced the manual electric energy chronograph, whose design is the same as the dashboard of the barrel case in Sportura series.
The Arctura manual chronograph made by Seiko came out in 2003, including a brand-new chronograph movement 7L22, which is much larger than 9T82. When fully charged, the 7L model can run for five months without wrist, which is an improvement compared with one month of the 9T model.
Kinetic watch stores electric energy in Seiko's original kinetic energy ESU (electric energy storage unit). As for how it works, unless you are an electrical engineer, it is a bit complicated to explain. Here is a brief introduction:
After the generated current is regulated by an integrated circuit (IC) composed of four micro capacitors, the voltage lever is pushed to quickly start the watch. At the same time, the integrated circuit (IC) also monitors the amount of current entering the ESU to prevent charge overload.
There is a way to determine when the battery is low. When Kinetic's battery drops to a very low level, the second hand starts to jump every 2 seconds instead of the regular 1 second. This means that the watch has only a few hours of power left and needs to be recharged. Some models of watches also have a battery storage indicator on the dial. To see how long the watch can run when it is currently charged, when the second hand points to 12 o'clock, press the button at 2 o'clock on the case. The second hand will move along the dial scale and stop at the position where the remaining power can last for several hours. The second hand returns to normal operation in 30 seconds or less.
Only a few watch companies have the ability to produce self-made quartz watch movements. Seiko is the first company to do this, and it is also a leader in this field. Compared with other watch companies, Seiko can produce more kinds of kinetic energy to generate timely movements. After Seiko introduced kinetic energy technology, two other companies also introduced quartz watch movements that generate electricity by swinging their arms. However, their movements do not contain Seiko's patented kinetic energy technology. Seiko's kinetic energy electronic storage system is extremely complex and precise. It can continuously increase the voltage when the battery is low to keep the watch running.
Both dynamic watches and automatic mechanical watches are penetrated by wrist movements, and it seems to be similar in this respect. In addition, automatic mechanical watches do not need batteries. There is no doubt that automatic mechanical watches are the driving force of automatic production. Both of them use the energy generated by the arm movement to drive the rotor pendulum to rotate to make the movement do work. However, automatic mechanical watches are not as accurate as electronic quartz watches. Automatic mechanical watches are driven by clockwork (not electricity), and they use a balance balance wheel (equivalent to a timely oscillation chip) to adjust the speed. In short, the accuracy of mechanical watches is kept within 5 minutes per month, while the accuracy of quartz watches is +/- 15 seconds per month.
