Watch is not waterproof, it is called a diving watch
Do you think that waterproof is called a diving watch? In extreme environmental environment, a reliable watch is an important guarantee for controlling the safe diving and returning time.But do you know? The watch is not a waterproof or a diving watch. The simple waterproof function does not mean that it is a professional diving watch.
According to the Swiss Watch International Standards (NiHS), diving watches must meet the following specific standards:
1. Safety device to control diving time
The NiHS standard stipulates that diving watches must have a safe device to control diving time.In addition, in order to prevent reading errors, the device must also be designed to prevent accidentally accidentally rotating.It is best to assemble the diving time rotating inner ring with a detailed minute scale. The device that controls the rotating inner ring should also have a corresponding safety start design.
2. Clear and easy to read
Time, rotating inner ring diving timing, or whether the movement is running or not must be clearly margin in the dark deep -sea environment. Generally, this distance (the straight line distance between the watch and the eyes) is set to 25 cm.Among them, fluorescent treatment is the most commonly used solution for major watch providers.

In order to ensure that the core components and straps of the watch do not change in the environment of salt water, the waterproof pads, bottom covers and mirror components of the diving watch should be adjusted accordingly. The common method is to increase the thickness.The NiHS standard stipulates that the case of the diving watch should reach the waterproof depth of more than 100 meters.
4. Magnetic, shock -proof and resistance to temperature changes
Professional diving watches are accompanied by anti -magnetic protection device, because the extremely sensitive swimming hairspring is likely to destroy its precision due to the influence of magnetic fields.The anti -magnetic protection device can prevent the movement from being affected by the magnetic field, vibration and temperature changes, thereby ensuring that the watch is accurate.In addition, a temperature change test is needed to perform temperature changes, and no steam condensation is found to be a good diving watch.
5. External force tolerance characteristics
The watch connection component should withstand the external force as high as 200N.
