1. (1) Steel: the combination of steel, chromium and nickel, refined steel, chromium and nickel, stainless steel processing is difficult, corrosion resistance and wear resistance are better than the former, the surface can be electroplated or not, only polishing or sandblasting, drawing sand treatment, forming different effects of three-dimensional appearance. Scratch can be repaired
(2) gold plating: rose gold, black, copper plated steel, discoloration in 3-5 years, scratch can not be repaired
(3) K-gold: K-gold refers to the alloy of gold mixed with other metals, which is short for K-gold because it is karat gold in English. For the precious metal part, the pure gold is 24K, but the pure gold is too soft to make watches. It must be mixed with other metals to enhance the hardness, generally silver, copper and palladium. However, no matter what kind of metal is mixed, the proportion of pure gold accounts for 75%. With the proportion of gold, silver and copper, five kinds of materials with different colors can be proced. The content of copper is represented by N. for example, the red gold with the highest copper content is represented by 5N, while the correct expression of platinum is white K gold. Scratches can be repaired
(4) titanium: with the upsurge of all steel watches, titanium is graally emerging. Its material is known as "aviation age" metal. What is titanium? Titanium is found in the earth's crust, its appearance can be bright and shiny metal, or silver gray, dark gray powder. Titanium is a kind of light, hard, heat-resistant and cold resistant metal with a layer of oxide film on its surface to prevent wear and corrosion. Scratches can be repaired
(5) gold clad: the case is made of stainless steel, covered with a layer of gold alloy, which is rolled into a whole by mechanical rolling. Its thickness is measured in micrometer, and 1 micrometer is equal to 1 / 1000 mm. Up to 10 to 15 microns thick, and generally only 2 to 3 microns thick. (6) copper: in wristwatches, copper is the best thing. It is cheap and easy to process. It is mainly used in movement. At present, most movements use brass alloy splint. We usually see yellow and white movement color, yellow movement is usually coated with titanium oxide, white movement is galvanized nickel alloy< (7) tungsten titanium alloy: first, tungsten carbide and titanium carbide powder are pressed into the embryo with a pressure of 1000 PA, then die-casting die is used, and then sintered into parts with high density in a special furnace at a high temperature of 1450 ℃. Finally, after several processes and grinding with diamond powder, the glittering tungsten titanium alloy is made with good wear resistance
(8) tungsten steel: high hardness, wear resistance, clear appearance lines, bright and clean, known as "wear resistance material". It can be used in combination with steel to make watch case ring mouth or watch band and grain to increase wear resistance and decoration of the surface of the case and band. High strength, scratch resistant, heavy and fragile
(9) precision ceramics: precision ceramics are bright and clean, wear-resistant, and don't hurt the skin. The main component is zirconia, which can obtain good processing performance under certain temperature conditions. Then, through advanced processing methods, it can be made into exquisite watch case and strap, or through special methods, various colors, which are more gorgeous and noble. Medium strength scratch resistant, the disadvantage is fragile
(10) composite glue: it is difficult to repair the scratch, and the general life span is 8 years.
(2) gold plating: rose gold, black, copper plated steel, discoloration in 3-5 years, scratch can not be repaired

2. It works
step meter watch
its motion sensor is a 3D acceleration sensor, which can sense the three-dimensional motion acceleration generated by human movement, such as walking and running, so as to record the number of steps per unit time. Through the input step to calculate the speed of the human body, distance, and through the input weight to calculate the calorie consumption. Its advantage is that it can be used for outdoor and indoor sports, not affected by the weather, and very energy-saving, and can store several days of sports data<
GPS watch
GPS Watch calculates the moving distance per unit time and calculates the moving speed by receiving the satellite position signal waypoint. The accuracy of position signal is determined by the strength of satellite signal and the sampling rate. For example, the accuracy of 1 second sampling rate is obviously higher than that of 60 second sampling rate. But too high sampling rate will lead to too fast battery consumption. Its advantage is that it can record the track of motion and synchronize to the map
heart rate watch
the heart rate watch measures the heart rate of human body by sensing the cardiac current of human body. The heart rate of human body is different in different exercise intensity. Internationally, the percentage of exercise heart rate in the maximum heart rate is divided into light activity: 50-60%, aerobic exercise: 60-75%, enrance training: 75-85%, and intensity training: 85% - 100%. Choosing different heart rate regions can achieve different training effects
of course, the above three basic functions can also be combined with each other, such as heart rate meter, step meter, GPS heart rate meter and so on.

3. We can consider amazfit intelligent sports watch 2S. This watch uses a high hardness ceramic watch ring with sapphire mirror, with a waterproof grade of 50 meters. It supports 11 sports modes such as running, riding, swimming, triathlon, elliptical machine, etc. with firstbeat motion algorithm, it can realize professional data display and motion suggestions such as VO2max, Under normal use, the enrance can reach 5 days, and support the Bluetooth headset and Bluetooth heart rate belt, Alipay offline payment, notification reminder and other intelligent functions, collocation wristbands and fluorine rubber wrist strap, can be quickly dismantled and replaced.
4. It's not necessary. It should be whether you need a watch instead of a mobile phone. Before, the price of professional sports watches was on the high side, and the popularity of watches was not so high. Many people use mobile phones to record. With the progress of technology.
5. Sports watch, as the name suggests, is a watch suitable for people to wear when they are exercising. Therefore, the most obvious features of sports watch series are multi-function and large and heavy case; Secondly, its & quot; Three Preventions & quot; Performance (waterproof, antimagnetic, shockproof) is much better than other series. Sports watches are also divided into different types, such as flying, climbing, running, diving and so on. Different types of sports watches have different designs and functions.
6. Consider the amazfit smart sports watch 2S. This watch uses ceramic bezel with good luster and hardness, sapphire mirror, quick detachable leather strap and fluororubber strap. The waterproof grade is 50m. It supports indoor and outdoor swimming, triathlon, running, elliptical machine, mountaineering and other 11 sports modes. With firstbeat algorithm, it can measure rich sports data, Support Alipay and Bluetooth music playback function, the normal use of life can reach 5 days, it is very worth buying.
7. CASIO, PRW-3100Y-1B, the official price tag is 2490, the price is fairly affordable, mainly the configuration comparison awesome, 6 radio and three processor, 100 meters waterproof, sapphire mirror, powerful, three processor can measure, side height, air temperature, night vision ability is also very strong.
8. Different sports watches are used with different apps. For example, amazfit smart sports watch is used with amazfit watch app, while Mido youth watch is used with Xiaomi sports. It is recommended to download the corresponding app according to the brand to the official website or consulting customer service.
9. Now many people wear sports watches, which can monitor the physical fitness and exercise volume of a day, which is also very good. But if you spend 3000 yuan secretly, first of all, you should tell your parents who gave you the 3000 yuan. If you earn the money from work, you have the right to control it.
