First, Automatic mechanical watches:
Refers to use of barrel storage powered watches. The beginning of all the power to send forces from the spring to tighten the fan in the second car, San Francisco, four-car fan, car fan V (escape wheel), then the balance wheel clamp, and then swing round reaction to the messenger, so that Prior to the location of their recovery, so that the process will make the whole operation cycle, continue to produce power. Mechanical hands can be divided into two kinds of chain and automatic chain.
A. hand list: leading by staff rotation, drive on the chain system in order to stimulate wound on the full chain.
Note: for the first time in my first time on a chain to the full chain on their own, should look at laps, then went the same way according to at least 8,9 points to, not on the chain too, to avoid spring break .
B. automatically on the list: the swing arm driven by the automated plate back and forth, to achieve the automatic effect of a wound.! ~ 3d?
Note: Automatic watch has a spring return device, so the unhappy chain, when the stop watch gone, so long as the last few laps winding walk to the other to rely on hand when the wearing of the swing to achieve the effect on the chain.
Second, Quartz quartz watch:?
Refers to the watch battery and crystal oscillator used to calculate and display the time, its movement is manufactured by the frequency of the quartz, and now can be divided into common Analog quartz watches and digital quartz watch, the biggest feature is accurate, the normal temperature range, the monthly error is about + - 15-20 seconds.
A. Analog quartz watches: the use of battery power to produce the frequency of quartz, and then using IC board divider and control coil and magnetic car, drive gear and rotate it a pointer, at which time, the minute hand is basically driven by electricity .. O
B. Digital quartz watches: Analog quartz watch basic principles and the same, but it does not gear, but directly to the liquid crystal film (LCD) to display the time.
Note: lC board walk normally for a long time, the contact point will be accumulated dirt or moisture, so also, and mechanical, like 2,3 years, maintenance of a wash oil, and wear for long periods of time is best to remove the battery to avoid battery fluid board out of the corrosion, wet weather in some areas, the choice of Japanese battery, would be more suiwatch.
Third, solar watch:
Solar cell is made using high purity silicon, this special treatment after the formation of two layers of silicon thin layer, when the sun or light exposure to the silicon surface, will be able to light into photocurrent and photovoltage. Current flows from the high voltage to low voltage solar cell watch battery and can be recharged. In order to prevent the inflow of solar watches the voltage is too high, and the internal resistance of the diode to act as a buffer to protect the watch battery and life.
Note: regular check of course, is ineviwatch, and the other to note that replacing the battery must be used to take plastic or bamboo forceps, using metal forceps easily lead to short circuit.
Fourth, automatic quartz watches:& \
It is the automatic watch with a combination of quartz watches, wearers of its power source from the swing arm automatic disk drive watch rotation, the kinetic energy generated by the system of micro-generation within the motor into energy for quartz watch device to provide adequate electricity, the excess energy stored will be micro-capacitors. The use of mechanical energy into electrical energy design, after today's technology continues to improve, the full energy, the sustainable operation of up to tens of days. Automatic quartz watch with automatic chain of convenience on the watch with the precision quartz watch, and without the use of batteries, more environmentally friendly, there are more and more brands make this type of watch.
Note: To regular maintenance, and avoid watchs placed in the local magnetic
Fifth, hand chain quartz:
SElKO Group from Japan, published in 1998 Spring Drive technology, most of the structure is identical with the mechanical watch, but the core of the mechanical watch escapement structure of a part of the structure using a quartz oscillator, so Some people think that it should belong to the quartz watch is, but strictly speaking Spring Drive technology actually be derived from mechanical design, because the quartz oscillator and magnetic car is in the Spring Drive above as "brake" effect, timing, power components source still comes from the barrel, provided by the quartz oscillator signals for consecutive points to put the magnetic car action to contain the second hand, so watch with Spring Drive technology, such as mechanical watches the second hand is a little bit like stepping, Because of the frequency with quartz oscillator core, so although regarded as mechanical watches, but have a month + - 15 seconds of high precision, but also where the reach of mechanical watches
