As the watch consumer market heating up, the watch has been out of the simple timing function as a symbol of personal taste and identity by more and more consumers love and favor. However, a large percentage of these people know little about watches. Therefore, we are here to introduce you to the basic knowledge about watches and how to easily identify the quality of watches. 1, watch classification and main features The current watch is divided into two categories: mechanical watches and quartz watches. (A) watches and clocks machinery (1) general mechanical watches (2) calendar, double calendar mechanical watches and clocks = ordinary mechanical clocks + calendar agencies or double calendar agencies. (3) mechanical clock, pendulum clock, wall clock and so on. (4) Automatic watch = ordinary watch + automatic mechanism (5) calendar double calendar automatic watch ordinary watch + calendar or double calendar agencies + automatic agencies (6) multi-function complex table: in addition to the calendar or double calendar and automatic, there are stops Seconds, stars, moon phase, leap year, moon, moon and other functions. main feature: (1) The movement is mostly metal parts. (2) The vibration system is usually a balance spring, the vibration frequency is generally 18000 times / hour ~ 28800 times / hour, that is, the balance spring assembly wobbles 5 times to 8 times per second; very few watch vibration frequency is 36000 times / Clock and floor clock using gravity as a vibration system, swinging 1 times per second. (3) Due to low vibration frequency, travel time accuracy is lower than quartz electronic timepiece. (4) power with a spring, elastic components, made of stainless steel alloy, the use of hand-winding mechanism or winding mechanism tighten the spring, the kinetic energy into spring elastic potential energy; spring relax, will be flexible Potential energy into kinetic energy, supply balance wheel hairspring assembly in the swing process of energy loss, and to ensure a certain swing. (5) The total number of parts more than the quartz watch. About 130 ordinary mechanical watches; calendar or double calendar about 200 automatic watches. Processing and more complex processes, about 1000 ~ 1500 Road. (6) Assembly and maintenance is more difficult than the quartz watch (2) Quartz electronic watch (1) Analog quartz watch: The time is the same as mechanical watches, calendar or double calendar and other functions. (2) Display quartz electronic watches: time display with digital display, can arrange more functions. (3) Hybrid Quartz Electronic Clocks: Hybrid Quartz Electronic Clocks = Analog Quartz Electronic Clocks + Display Quartz Electronic Timepieces. Combine the two movements together, share one battery or one battery, respectively, to achieve the pointer indication and the digital display time. main feature: (1) The system uses quartz oscillator. Vibration frequency is generally 32768 times / second, (2) travel time high precision: Japan and usually 0.5 seconds, that is, 15 seconds / month; high-precision annual difference of 1 to 2 seconds. (3) The movement can be designed and manufactured very small and thin: minimum movement of 3.5 orders; the thinnest movement of 1.2 mm. (4) fewer movement parts, pointer quartz electronic watches about 30% of mechanical watches; display quartz watch zero less, there is no metal transmission, only a small amount of buttons, reeds and screws. (5) Energy Battery: There are chemical batteries and physical batteries. (6) Assembly, maintenance more convenient. 2, the composition and role of watches and clocks by the movement and appearance of two parts: Movement - the exact body of the time, a variety of structures. Different brands of watches can use different or the same movement; even if the same movement, different brands, select the movement of quality indicators are also different. At present, the world's clock and watch manufacturer has gradually moved towards a specialized factory that produces standard, standardized and serialized machines with production movements for the production of brand watches and clocks. Only some brand-name watch manufacturers have a long history of maintaining their own unique style and still using their own movement . The movement is also not allowed to take-away, to eliminate the occurrence of counterfeit phenomenon. Appearance - The package that protects the movement from the normal operation and the user's wearing mainly includes the case, back cover, crown, dial, pointer (indicator) and watch band. They are combined to be beautiful and durable. More for the watch dustproof, waterproof, that is, a good seal. Watch Fake Commodity Recognition Modern watches are the crystallization of the precision machinery industry and the microelectronics industry. The world's light watch brand, say less there are thousands of species. According to its quality and price points, nothing more than high, medium and low three categories, the real name is only within a hundred species. Currently showcased brand-name watches have 1 to 2 years of history.
