The service life of a watch is related to whether the wearer uses and maintains the watch correctly. For example, wearing a watch to take a bath, the watch looks dirty, the strap length is not suitable, and the use environment is bad, which can easily lead to the damage of the watch and shorten its service life.
High-end watches should be maintained every two to three years, such as replacing waterproof parts, testing the running performance and power consumption of the movement, cleaning the movement and maintaining the appearance. This kind of maintenance service will effectively extend the service life of your watch.
The waterproof of watches depends on the waterproof aprons of the mirror top, back cover and handle to reach the corresponding standards. The words "waterproof" or "waterproof" are printed on the bottom cover of all waterproof instruments. Watches without waterproof signs can only prevent dust, so avoid water. A waterproof meter of 30 meters (3 atmospheres, that is, 3 atmospheres) can be used for daily grooming or raining, that is, water droplets only splash on the surface without any water pressure being added to the meter. 50m waterproof meter can be used for swimming and general housework, and 100m waterproof meter can be used for underwater work such as swimming and diving.
The aging of waterproof apron will affect the waterproof performance of the watch, so the waterproof apron and handle (including waterproof apron) of the watch should be replaced regularly according to the use situation. Every time the quartz watch changes batteries, the waterproof components must be replaced at the same time to ensure good waterproof performance.
Any waterproof instrument should not be used in a hot bath, sauna or in an environment with great temperature changes. Because the waterproof apron is affected by temperature, it will expand with heat and contract with cold, resulting in cracks, accelerating aging, causing water and condensation on the surface, seriously damaging parts.
