What is the classification of watches?

According to the power source, watches can be divided into mechanical watches and electronic watches:

Mechanical watch:

The movement of ordinary mechanical watches has 90 to 100 parts, and the movement with more functions has 1400 parts. The energy of a mechanical watch is a coil spring, and the energy stored in the spring drives the watch to work to achieve the purpose of timing. Mechanical watches can be divided into manual mechanical watches and automatic mechanical watches:

(1) Manual mechanical watch: refine the movement by hand, turn the crown, and the spring in the movement will release energy to drive the watch to run.

(2) Automatic mechanical watch: the power of the self-winding movement is driven by the weight of Feituo in the movement. When the arm wearing the watch swings, it will drive Feituo to rotate, and at the same time drive the internal wind-up to wind up the watch.

Features of mechanical watches: (1) Unlike quartz watches, the second hand of mechanical watches moves continuously.

(2) Due to the complexity of the mechanical watch movement, the travel time error is large (depending on the brand), and the error of the Observatory movement is small. It is normal that the error is within -4/+6 seconds a day. The travel time error of a mechanical watch cannot be accumulated, and the watch needs to be debugged for a period of time.

(3) The process is fine and easy to use. It can be wound for more than 36 hours.

(4) The movement has a long service life.

(5) The appearance is thicker than quartz watches (see brands), and some brands are also very thin, but they are generally manual mechanical watches.

electronic watch

It can be divided into digital chronograph, pointer chronograph, automatic quartz watch and optical kinetic energy meter.

1. Digital Timekeeping Electronic Watch: A watch that combines the piezoelectric effect of timekeeping crystal and the display of bipolar tube liquid crystal, and its function is completely completed by electronic components.

2. Pointer quartz watch: The energy of quartz watch comes from silver oxide button cell. After the silver button cell oxide provides a specific voltage to the integrated circuit, the oscillator vibrates through the oscillator circuit and the quartz resonator in it, forming an oscillator circuit source. The electrical signal with the frequency of 32768Hz output by the oscillating circuit enters the frequency dividing circuit, and after frequency division by 16, a pulse signal of 0.5hz is generated, and then the pulse signal output by the narrow pulse circuit enters the driving circuit for amplification to form an alternating bidirectional pulse signal, thereby driving the stepping motor to rotate intermittently, and further driving the transmission gear train, so that the watch hands can accurately display the time.

Battery-provides energy to ensure the normal operation of the circuit.

Circuit part-provides electrical pulses with stable frequency and power to drive the stepping motor to rotate.

X stepping motor-converts part of the electric energy output by electronic devices into mechanical energy.

Transmission gear train-the mechanical energy output by the motor is rotated and transmitted to the second wheel, minute wheel, hour wheel and calendar wheel step by step.

Pointer moving mechanism-drives the pointer to rotate to indicate the time.

Needle setting mechanism-adjust time and calendar, weekly calendar, and also have the function of stopping seconds.

Features of quartz watch:

(1) The second hand of the quartz watch is jumping every second, which is very accurate. Generally, the monthly difference is required to be within 15 second, including three stitches and two stitches.

(2) The integrated circuit is used in the movement, which is much simpler in structure and very simple in assembly than the movement of a mechanical watch.

(3) Easy to use, no need to wind up when wearing, and a battery can generally be used for 2-3 years. However, some lithium batteries of quartz watches have a long life, which can be used for about 7-8 years.

(4) Quartz watches are relatively cheaper than mechanical watches (the same brand and style), but some high-end brands are expensive because of their good brands, good appearance materials (18k gold or diamonds or precious metals) and excellent design, which leads to some quartz watches being much more expensive than general mechanical watches.

3. Automatic quartz watch: It combines the advantages of automatic mechanical watch and quartz watch. It does not need batteries, and the wearer can choose to wind it manually or charge it automatically. Its electronic timing device makes it more accurate, with a monthly error of less than ten seconds. Its working principle is to use the swing of the arm to drive the flywheel in the instrument to rotate and generate energy to push the internal micro-motor to convert into energy, thus providing sufficient power for the timely device in the instrument, and the excess power will be stored by the micro-capacitor for standby. After the watch is fully charged, it can run continuously for more than nine days without wearing it on your wrist. At present, Swiss Tissot Watch and Japanese Seiko Watch are both famous automatic quartz watches.

4. The working principle of the optical kinetic energy watch: firstly, the optical energy is converted into electric energy through the solar chip, and the electric energy is stored in the recyclable titanium lithium ion rechargeable battery, and then the battery generates electric energy. ......

What category is a smart watch?

Only watches should belong to digital products.

What kind of watch is good?

There are some errors in mechanical watches and automatic mechanical watches. Work normally for 20 seconds every day. This process is demanding and costly. Wind it up every day

I use a mechanical watch 126 RMB, which I bought from Taobao and wind up every day. Now that everyone has a mobile phone, who will use a watch to tell the time?

A watch is just a kind of jewelry. Watch: a man's jewelry. Regular maintenance of mechanical watches takes about 1 year. Go to the watch repair shop and oil them or something. If it is not waterproof, pay attention to it at ordinary times.

The battery used for quartz watch runs well for 3-4 years without any problems. It is characterized by accurate timing. The disadvantage is that you have to go to the watch repair shop to change the battery in a few years. From the use point of view, the maintenance cost of quartz watch is lower than that of mechanical watch, because as long as a button cell from 5 yuan is enough for you to use for several years, the cost performance ratio is higher than that of mechanical watch. High-end watches are all mechanical because of high manufacturing technology. From the collection value, the collection value of mechanical watches is high. A good mechanical watch can be passed down from generation to generation as a family heirloom. Mechanical watches symbolize taste, accomplishment and so on. Why did I only buy a 126 RMB mechanical watch? Because I think it makes me look low-key, but my popularity is high. As for someone buying a Rolex with hundreds of thousands as a local tyrant, there is no objection. From the watch, we can actually see a person's values, aesthetics, ideology and many other aspects.

Electronic watches are accurate and modern, suitable for sports people and of great practical value, because they are more cost-effective than quartz watches. And for button cell.

The radio watch conference is actually a quartz watch with a radio receiver receiving timer, which has an error of 1 second compared with the time of 300,000 years. People who are time-critical can consider radio meters.

Light energy meter, also called solar energy meter, receives light radiation, and the energy storage point of silicon battery converts light energy. There is also a battery in it, and the battery has a service life. Suitable for outdoor workers and people with long sunshine hours. Exposure meter can receive light for 4 hours and then use it for more than 20 hours. Personally, I think this meter has low controllability. If it is connected to the rain gauge, it will stop.

To supplement the added value of watches, first of all, the intrinsic value of famous brands must be lower than the added value of brands. That's why rich people play watches. Personally, I think it is suitable for lazy people and mechanical watches are suitable for hardworking people. Personally, I suggest you choose a genuine domestic mechanical watch below 300.

What is the difference between the movement types of watches and which is better?

According to the type of movement, there are mechanical watches (manual/automatic) and quartz watches.

The manual movement core is the movement that manually winds the crown.

Automatic movement is a kind of mechanical movement that adds an automatic winding system to the spring of the clockwork device, and it is automatically wound through the worn movement. The heavy metal or gold rotor is semicircular, connecting the middle of the movement and acting as a pendulum. A set of reduction gears with paired coupled rotors can continuously wind up the spring in motion.

The time base of the chronograph movement is made of chronograph, and the battery provides power. The daily error of the timely movement is 0.0 1 sec, which is 10 times more accurate than the mechanical movement.

There is no good or bad choice. As a part that can be mass-produced and copied regularly, timely movement is widely used in entry-level brands and products. Like swatch, Tissot Longines.

As a precise mechanical device that stores, transmits and utilizes energy only through gear meshing, the mechanical movement tests the manufacturing process and technical level. Manual or automatic mechanical movements contain more parts than synchronous movements. Mainly relying on manual assembly, mechanical watches have risen from tools to handicrafts. General high-end brands or top Swiss watchmaking brands are proud of making their own mechanical movements. Jaeger-LeCoultre, Rolex and other brands that can produce their own products with parts are regarded as the benchmark of high-end watches. The price of mechanical watches is generally much higher than that of quartz watches.

For better or worse. Just to see if you know your needs. When buying quartz watches, they are generally used as tools. And mechanical watches, when you pay a higher price, you buy more feelings and recognition of precision machinery.

What category does the watch belong to in Tmall?

Jewelry.

What industry does the watch belong to?

Commodity industry, of course. . . In fact, there is no difference. Now both are fine.

Brand classification of Swiss watches

Clocks and watches brand/kloc-In the 6th century, Calvinists introduced the technology of making clocks and watches to the Jura Mountain area on the border between France and Switzerland. For centuries, watchmakers have created the world-famous Swiss watch industry with the spirit of pursuing perfection and continuous innovation. Many world-class watch brands, such as Patek Philippe, Blancpain, Breguet, Jaeger-LeCoultre and Earl, are all made in Switzerland. The Swiss Watch Association announced the 20 10 ranking of Swiss top watches (this ranking was announced by the Swiss Watch Association).
