[0002] In the field of precision manufacturing, especially in the watch industry, the waterproof performance of the case crown (usually refers to the crown, used to adjust the time and date, etc.) is an important factor related to product quality and user experience. The waterproof performance of the case crown not only directly affects the durability and reliability of the watch, but also determines the applicability of the watch in complex environmental conditions. Therefore, strict waterproof testing of the case crown is a key link in ensuring the quality of the watch.

[0003] There are many kinds of waterproof structures of watch cases on the market, such as screw structure, piston structure single O-RING, piston structure double O-RING, etc. These waterproof structures have their own characteristics, but also have some common defects, such as unstable waterproof performance, easily affected by the use environment and usage habits, etc.

[0004] Although the screw structure bar has a better waterproof effect, it is difficult to tighten and easy to slip, especially in a water environment. It is more inconvenient to operate; the piston structure single O-RING bar and double O-RING bar are easy to operate, but under high waterproof requirements, their waterproof performance is often difficult to meet the design requirements.

[0005] In order to ensure that the waterproof performance of the watch case meets the design requirements, it must be subjected to rigorous waterproof testing.
