What Is a Water Resistant Watch?

Waterproof watches are divided into ordinary waterproof and professional waterproof. Ordinary waterproof watches can only prevent water splash, while professional waterproof watches can withstand immersion in water at different depths. The waterproofness of the watch depends on the waterproof rubber ring on the mirror, the back cover, the handlebar, etc. to meet the corresponding standards.

(1) The waterproof rubber ring is easy to deteriorate and deteriorate, so it should be replaced regularly, or it should be replaced at every repair.

1, bite mouth waterproof structure. It differs from the threaded mouthpiece type in that the bottom of the case is threaded, and the grooves on the main case frame and the bottom case are biting each other. The selection structure is only found in "

The waterproof specifications of general watches are divided into the following types: 30 meters, 50 meters, 100 meters, 300 meters, 500 meters.

30 meters: refers to the general waterproofing of life, that is, water droplets splashing when washing hands, and raindrops falling when it rains lightly, but be careful not to take too long.

At present, any waterproof watch, whether it is marked XX meters, can not be used in hot water (> 40C °). There are two reasons for this: 1. The permeability of water molecules is greatly enhanced when the temperature increases, and all waterproof watches are designed based on cold water. 2. According to thermal expansion and contraction, some components of the watch will expand to varying degrees under hot water conditions, resulting in an increase in possible gaps.

1. Spiral waterproof watch. The upper case and the rear case of the watch have threads, and the upper case and the rear case are tightly screwed by the action of the threads. The watch glass is rolled in with a tool and is relatively tight. Waterproof gaskets (mostly made of nitrile rubber) are placed in the winding crown and the place where the back cover and the upper case are screwed, so it can play a certain waterproof role. This waterproof watch has a notch on the outside of the back cover of the case and a convex part on the polygon. The back cover of the switch must use appropriate tools.

2. Buckled waterproof watch. The back cover has a high convex sub-opening inside, so that the upper case and back cover can be tightly buckled. The watch glass and the spiral waterproof watch are also rolled in with tools and are relatively tight. Waterproof gaskets are also placed in the top of the winding crown and in the areas where the upper case contacts the back cover. The back cover of this waterproof watch is opened with a knife, and the back cover is closed with a rolling tool or pushed with a finger.

3 Slip-on waterproof watch. Its upper case is pressed against the bottom case. The shape of the back cover of this watch case is quite special: there is a high wall around it, the movement is installed inside the wall of the back cover, the watch glass is directly covered on the wall of the back cover, and the upper case is pressed in , The watch glass and the back cover are tightly wrapped, so as to play the role of sealing and waterproof. The winding stem is connected by the upper and lower sections. When the rear cover is opened and closed, the winding stem and the winding stem of the upper section are removed first, and the special section is used to open and tighten. Without special rolling tools, fingers can be pushed.
