If you want to be a wrist, you should not only choose a watch, but also how to protect your love watch. You must remember to use the 6 restricted areas below.
1. Can't the watch be with the camphor?
The molecules of the camphor volatile are easy to react with the lubricating oil in the watch movement, so that the lubricating oil deteriorates and loses lubrication, so the watch can not move normally, which directly affects the travel time accuracy and service life.
Therefore, the watch should not be stored with the camphor. When the watch needs to be stored for a long time, it should be dry, clean, and not exposed to direct sunlight, and should be moved around the watch every few months to prevent the time from being too long, the oil on the watch is sticky and affecting the time.
2. The watch cannot be used in a strong magnetic field environment
The magnetic fields in daily life are: generators, motors, radios, televisions, mobile phones, keyboards, etc.
Calling with a hand wearing a watch will also be magnetic.
The anti-magnetic ability of the general mechanical watch can only achieve the anti-magnetic effect within a limited range. If it exceeds its anti-magnetic ability, the steel parts inside the watch will be magnetized, and the hairspring will be affected, resulting in inaccurate walking time of the watch. Going fast, there will be serious stops.
In addition, does the magnetic field affect the quartz watch? Although there are few steel parts in the quartz watch, strong magnetic fields can also interfere with the normal operation of the rotor. Therefore, the general watch can not be used in a strong magnetic field environment, and the watch can not be placed on electromagnets, speakers, generators, transformers and large electrical equipment.
3. The watch is afraid of severe vibration and shock
When participating in sports activities or other manual activities with a large amount of activity, try not to wear watches to avoid unnecessary losses.
The watch is a sophisticated timing tool with small parts, and the mechanical watch only relies on the shockproof performance of the shock absorber to prevent vibration. There is a limit to the vibration range. Exceeding the effective range of the shock absorber, the tip will be damaged first.
In addition, other parts of the mechanical watch, such as the hairspring, the drill hole, the wheel shaft tip, etc., may be damaged or damaged by severe vibration. Although there are no wearing parts such as sharp points and hairsprings in quartz watches, large impacts can cause damage to electronic components and affect the use of watches.
At present, there are many watch appearance parts made of ceramic, hard alloy, sapphire glass, etc. Although these materials are high in hardness and wear-resistant, they may crack under sudden drop or impact.
4. General waterproof watch can't take swimming
Waterproof rating 1: 30m / 100ft or 50m / 165 feet, only to prevent splashes of water and rain.
Waterproof Level 2: 100m / 330ft or 200m or 660ft, to prevent splashing water and rain and to wear for diving swimming.
Waterproof rating 3: Water resistance up to 300 meters / 1000 feet, can be worn for free diving or water sports.
In the eyes of many people, I think that my watch is a waterproof watch, it can be waterproof, I don't have to take it when I swim, but the idea is wrong. Because the general waterproof watch is not a swimming or diving watch, although it uses sealing measures to prevent water splashing and daily sweat intrusion, it should not be submerged in water.
The waterproof depth marked by meters or atmospheric pressure on a general waterproof watch is the theoretical waterproof depth when the waterproof test is carried out in the laboratory. The watch and the water are both at a constant temperature and at rest during the test. In real life, this kind of constant temperature and stillness does not exist. The activity of wearing a watch in the water will greatly increase the water pressure on the watch. Therefore, it is best not to wear a normal waterproof watch to swim or bathe.
5. The effect of chemicals on the appearance of the watch
In daily use, watch should avoid contact with chemicals and acid, alkali, salt erosion, so as not to cause damage to the appearance of the watch.
The appearance of many watches, such as the strap, the case is gold-plated, chrome-plated or titanium carbide, the coating is thinner, mostly less than 3mmy, and some cases, the strap itself is a plastic shell, if the appearance of these watches or The coating is exposed to and corroded by chemicals such as gasoline, alcohol, paint, cosmetics, sprays, pesticides, water-based solvents, and mercury after the thermometer is broken, which may cause discoloration, corrosion, and even delamination.
6. Adjust the restricted area of ​​the watch calendar
Calendar watch, if you can't use the speed dial mechanism to change the date at some time during the work, this time is called the restricted area.
During the time of the restricted area, the dial on the day wheel of the calendar mechanism is just in the backlash of the date ring. If the calendar is adjusted by the speed dial, the rotation of the date ring will be hindered by the dial, which will damage the parts. . Therefore, it is not possible to quickly adjust the calendar during the time zone.
However, calendar watches with restricted areas are mostly slow-climbing calendars. The day starts from around 10 pm and is completed around 12 o'clock. Its dial and dial wheel are a fixed steel body. The current fast-climbing calendar and instant-jumping calendar mostly use elastic dials, which eliminates the restricted area. However, for the sake of safety and security, it is recommended that you choose the quick calendar adjustment during the day.
