Information

The waterproof structure of the back cover of the knife. This kind of waterproof watch is often ignored by people and mistaken for a general watch. Although it uses a knife to cover the back cover like an ordinary watch, it is much tighter. The watch handle and the back cover are also padded with rubber rings, which can also play a waterproof role. The famous "Armani watch has also used this waterproof structure.

Water resistant watch

Decompression waterproof structure. The bottom case is a concave steel bowl, the watch mechanism is installed in the steel bowl, the tight ring and the watch cover are pressed, the main frame is fastened to the watch case, and the waterproof performance is still good. Its characteristic is that the case has no threads, the back cover is rounded, and the edge of the cover has a sealing gasket, which is tightly fitted by extrusion and can be pried open with a blade. It's just that the string stem (commonly known as the self-made rod) is a double-section rod, and the joints are easy to store water and rust. Imported "Swiss watches" are mostly of this type.
Screw-on waterproof structure. This is the most common and main type of waterproof watch, and all domestic watches use this structure. Its characteristic is that the back cover and the case are connected by threads, and a sealing gasket is pressed. The edge of the back cover has 8, 10, and 14 symmetrical corners, which can be opened with a watch opener. The "Flying" and "Russian" brands of the Soviet Union should also belong to this category, although the bottom has no thread and is closed with a threaded rear ring.
