The watches are classified
Mechanical watch
The timing instruments of the mechanical vibration system, such as clocks, wheel clocks, etc.Its working principle is a vibration system that is constantly vibrating with a constant cycle.Multiplying the vibration cycle during vibration is equal to the time passed, time = watch vibration cycle × vibration number.It is generally composed of energy, wheel system, escapement agency, vibration system, pointer agency, and additional agency.Dynamics-section or heavy hammer, providing energy when working with mechanical clocks, can run through the gear system for many days through the growth rate of the gear system.The rudder or the wheel controls the speed of the clock, and the time for the reporting (reporting) institution tells people: What time is the last sound just now.
digital watch
The basic part is composed of electronic components.The working principle of the electronic clock is to convert electrical energy to magnetic energy, and then from magnetic energy to mechanical energy to drive pointer operation.
Crystal tube swing wheel meter
Taking dry batteries as energy, transistor as switches, and swimming shots as oscillation systems.
Quartz watches
It is used as an oscillator with "quartz crystal". The motor operation is controlled by electronic frequency, which drives the pointer. The time is high.Electronic needle table.That is, the combination of the electronic movement and the quartz movement, which has both an electronic display and a watch instructions for walking instructions.Such movements such as the T250 movement of Citizen Miyota Co. (LTD).
Light wave
The light -powered radio watch receives the "standard time" radio waves issued by the transmitting tower through the built -in radio receiver and antenna of the watch, obtain data such as time and calendar, and automatically correct the time and date of the watch.The standard time signal uses the theory of high -precision 铯 atomic watches, with a 100,000 -year error of one second.The radio wave watches of the West Rail City use all the light power technology, using any visible light source as the energy -driven.As long as there is light, there is energy, as long as it can receive the radio waves, there will never be errors.
Electronic paper watch
Electronic paper watches are watches equipped with electronic paper displays inside, which can display time, week, date.The implementation of electronic paper technology mainly includes cholesterol LCD display technology, electrophoresis display technology (EPD), and electrical wet display technology.The electronic watches used in electronic paper watches mainly use electrical display technology.The display brightness and contrast of electronic paper watches are high, and there is no need to use backlight to improve readability.The electronic paper display used in the electronic paper watch has a simple hardware structure and a thickness of about 1mm.It is the new force in the watch army.
Diving watch
The so -called diving watches, as the name suggests, refer to watches that have been used after waterproofing and diving.General waterproof meters cannot be used to dive. The diving watch must meet strict regulations. It is not a diving meter if it is not waterproof enough.The standard waterproof performance of the diving meter is at least 100 meters of water depth; there is an outer ring that can rotate unilaterally on the bezel to measure the diving time; divers are often in the dark water, so the pointer, scale or surface of the diving watch is usually necessaryApplying fluorescent materials can make users read more easily.Common brands of diving watches include: Rolex, Finnish SUUNTO element series water spirit diving watch, Omega hippocampus Ploprof series diving watch, Haoya Submarine series, Wlanosacar Super Submarine series, and so on.
