Ordinary quartz electronic watches daily error less than 0.5 seconds, a few mechanical watches are one-tenth, which is mainly due to quartz crystal oscillators form a high and stable oscillation frequency. High frequency quasi-going when the truth is that people in long-term research how to improve the accurate clocks go when they find a principle, the higher the frequency of oscillator, oscillating more stable, stronger anti-interference ability, watches more accurate. Quartz electronic watches the oscillation frequency of 32768Hz, before quickly than ordinary mechanical watch 3Hz per second high-frequency 10,000 times. Therefore quartz electronic watches more accurate than mechanical watches. In addition mechanical watches because of structural problems in table body, the role of Earth’s gravity, horizontal position and vertical position of the offset potentiometer will produce, spring up from tight to relaxed, torque imbalance, coupled with at outside temperature, magnetic field, vibration, etc. impact, mechanical watches, even if further enhance some frequencies, it is impossible to achieve precision quartz electronic watches.
Waterproof watches in use should pay attention to?
(1) waterproof apron easily degenerate aging, it is necessary to periodically replace or repair at each replaced.
(2) Table glass can damage the water table affect the performance, there should be a timely replacement of damaged.
(3) not to watch in the water or humidity, the operator watches the first handle to prevent the water table into the machine.
(4) handle after the first use of want in the end push, screw button locking handle in the first attention should be paid to watch on, not gap.
(5) watch the water wash to dry at any time.
(6) to prevent exposure to chemical substances watches will be affected watchcase and waterproof apron, reducing water resistance.
(7) watches a long time not to put up on the high temperature (10 60 ℃) and low temperature (-10 ℃) environment.
(8) If there is water aerosol watch point, should be cleared, so as to avoid mechanical rust.
How to judge a watch when going Whether or not accurate?
(1) if the watch every few days on from time to time with the radio time signals are basically the same, this is an accurate table when going.
(2) watches from time to time with the start of radio time signals, but every day there is error after running. While the cumulative increase, but the increase in error every day is the same. If you go when the error does not exceed the quality standards of the table, this is also a qualified table. If the error exceeds the required standards, you can switch speed needle adjust when going to make it more accurate.
(3) If the watches with radio time signals on the table, sometimes, sometimes fast, there is no certain regularity, but the error is very small, probably with the use of status, but also a qualified watch. If the error is too large, there is no law, nor can speed through the needle to adjust the exercise, their accuracy can not be guaranteed, it would take through the proofing overhaul to make it when going with the required standards.
Why should not normally watch wearing waterproof swimming?
Although the general watch seals taken measures to prevent the sweat and the intrusion of harmful gases, but not definitely not water. At the same time watch the process will be used at some inevitable phenomenon: every day be set aside on the needle, shank or handle the first head tube will gradually wear the band. Table glass affected by temperature and will appear on it with watchcase gap; rear cover waterproof apron sweat effects of aging or corrosion, the above will cause the waterproof sheet waterproof performance. Therefore, the general water table can not be wearing go swimming, take a bath. Is washing clothes, washing dishes, cooking time should also pay attention to, not to make the water spilled on table or water vapor into the person table, otherwise mechanical water table will rust, affecting the quality of travel time, or even lose value.
