These familiar watch facts you need to remember!

1. The watch is not kept away from the magnetic clasp?

Both mechanical and quartz watches are sensitive to magnetic fields. For mechanical watches, since most of the movement components are made of steel, they are susceptible to magnetic fields.TUDOR Black Bay M7941A1A0RU-0003 If the watch is near the vicinity of a strong magnetic field, the hairspring of the movement will be magnetized, thus affecting the accuracy of the timekeeping.

Similarly, quartz watches are afraid of magnetic fields. The quartz movement has a stepping motor inside, and when affected by a strong magnetic field, the rotor will stop at a fixed position, causing the second hand to stop.

If the watch is strongly magnetized, simply purchase a compass and hold it close to the watch. If the compass deflects, the watch is magnetized. At this point, the watch needs to be taken to a professional repair shop for demagnetization.TUDOR Ranger M79950-0001 Therefore, pay attention to the clasp around!

2. Wearing a waterproof watch in a sauna?

Waterproof watches usually have waterproof performance greater than or equal to 30M level, but even ordinary diving watches only have waterproof ability at room temperature. When subjected to large temperature changes, such as wearing to the sauna or the impact of ice water, will affect the normal service life of the watch.

At high temperatures, the lubricant will rapidly diffuse and oxidize and deteriorate, losing its lubricating effect; the sudden stimulation of icy water will cause the air inside the watch to condense and fog up, and at the same time, the waterproof rubber ring of the watch will be easy to accelerate the aging under the effect of heat expansion and cold contraction, thus affecting the waterproof performance.

Therefore, you can dive in the sea, but do not use the diving watch to take a bath or sauna!

3. Watches are never maintained?

Mechanical watches, like automobiles, require professional maintenance to ensure lubrication and smooth transmission between mechanical parts. Generally speaking, mechanical watches should be sent to a professional watch repair point every 3-5 years for a series of maintenance such as oil washing and replacing the waterproof rubber ring. If it is a diving watch, it is recommended to maintain it every 2 years. Individual brands and technologies can extend the maintenance period of watches. Therefore, pay attention to regular maintenance to keep the watch in a healthy state!

4. Sapphire crystal never wears out?

The sapphire crystal on the watch is not made of natural sapphire, but it is also resistant to wear and corrosion. It has a hardness of up to 9 on the Mohs scale, second only to diamonds and seven times that of steel.

However, it does not never wear out, but is not susceptible to wear. Avoid contact with diamonds, whetstones, sandpaper, nail clippings, granite surfaces, concrete walls, etc. during wear to avoid scratching the surface. However, you will not be idle to do these destructive actions.

5. The watch is idle without insisting on winding or removing the battery?

For mechanical watches that have not been used for a long time, they should be stored away after cleaning and refueling. To prevent the internal oil from drying out, you should wind the watch 1-2 times a month when it is idle to keep it running well. For quartz watches that have not been used for a long time (i.e., beyond the expiration date of the battery), it is recommended that the watch be sent to a professional repair point to have the battery removed. Quartz watches mainly use silver oxide batteries, which operate similarly to dry cell batteries. Even when it is not in use (e.g. in storage), it is self-discharging. When the battery is dead, it is prone to alkali creep and liquid leakage. Liquid leakage is highly corrosive and can cause serious damage to the circuit board of a quartz watch.

6. Do you not clean the exterior parts of your watch often?

The most commonly used material for watches is stainless steel, the main components of which are nickel and chromium. Elements such as nickel and chromium are susceptible to erosion by strong acids and alkalis. The sweat excreted by the human body contains hydrochloric acid, and when wearing a watch, if it is often touched by sweat or if it is allowed to accumulate acid and alkali salt dirt without timely cleaning, the watch band, case, etc., will gradually appear corrosion marks. The simple treatment method is to use a soft-bristled toothbrush dipped in cleaning agent to gently brush and dry with a soft cloth. However, for the sake of insurance, it is recommended to use ultrasonic instrument to clean the watch at the professional maintenance point.
