From the momentum can be divided into: E-table (including the quartz watch, light form of kinetic energy), mechanical watches, radio table.
Mechanical watches
Mechanical watches can generally be classified into the following two: the hands of smelting and refining automatic watches (AUTOMATIC) two.
Both machines are on the impetus for movement within the clockwork as the driving force to bring gear to foster the development of hands, but the way power sources are different. Lian mechanical hand by hand on table Xiaolian, the thickness of movement than the average auto on the table Xiaolian some thin, the relative weight of the whole watches on a lighter. Lian automatically on the watch, is the use of movement around the bottom of the plate before automatically pass to the momentum generated by wind-driven energy generation, but the relative thickness of the watches will have a more general Lian watches thicker.
The advantages of mechanical watches is: through regular maintenance wash oil, you can use a very long time; but the drawback is: the error than the quartz watch large, due to the production of high quality and form the internal movement of the impact of the vulnerability of gravity errors. Usually the error is a mechanical watch every day the number of seconds to calculate the difference, and the quartz watch is based on monthly deviation of error for calculating the number of seconds.
Electronic form (including the quartz watch and optical kinetic energy table)
First of all, to correct us all a misunderstanding, quartz table and light table from the kinetic energy provided by way of motivation is still belong to the scope of electronic watches, and optical access to energy, kinetic energy is just different.
Quartz watch is a kind of electronic watches, quartz movement that is to say that a class of electronic movement. Usually, an electronic movement that generally refers to the closed-loop circuit of semiconductor crystal oscillator. While the quartz movement, said quartz crystal oscillator.
Two different forms, in fact, present in almost all occasions the electronic forms category, use the quartz crystal oscillator, including the computer’s clock (the kind that save time, not CPU chips such as the shock circuit) are used quartz the oscillator. Quartz oscillator, at least to the current view, the time is still very accurate, looks similar to capacitance, there is a metal casing, the internal oscillator is packaged in a.
And the quartz watch is the use of quartz oscillator signals, drive stepper motor driven gear and let the rotating table. Electronic watches are usually quartz oscillator signal will be amplified through the LCD screen display
Optical principle of kinetic energy generation in the watch panel below, the installation of a light source will be able to receive electricity generation “solar panels.” Then solar panels created by energy, stored in a “secondary battery”, the driver watches as a functioning power source. Receiving the light source, the storage of electrical energy; in the absence of light, the secondary battery operation automatically provide motivation! Light in a transparent mirror glass, crossing over the surface of panels in the solar panel condenser and absorption, and finally stored in the secondary battery Lane; energy driving force, moment to complete.
Radio Table
The so-called wave table, the fuselage by the atomic clock and radio receiver system, granted by the National Center on accurate time when, through the radio receiver system for receiving, processing by the CPU after the show time, wave form error of 30 years will not be more than 1 seconds. Simply put, is an accepted standard time wave information will be able to automatically watch time checks.
High-sensitivity small table radio with built-xxx, to receive the standard radio wave to carry out automatically, the result can be achieved accurate time. Currently in the international arena, Germany, Britain, the United States, Japan already has the standard radio wave sent. July 2007, in China Henan Shangqiu built a new radio tower has begun to send waves.
Following the wave form will be replaced by mechanical watches quartz watch has become the market mainstream watches watch industry after another revolutionary technology products.
