The bottom cover of a watch is usually of three types: 1. The bottom of the teeth (the top of the bottom cover is composed of countless teeth). This type of bottom cover must be round bottom with good waterproof performance. High-end watches such as Rolex and Tudor are such bottom covers.
2. Bottom of screw (the bottom cover usually has 6 small notches, very few only 2 small notches). This kind of bottom cover must be a round bottom, which is generally used for middle and high-end watches.
3. Ordinary bottom (usually there are small special pry openings at the 7 or 11 character position of the bottom cover. In addition to the pry opening, some watches have 6 small notches on the bottom cover, which are fake screw bottoms). This type of bottom cover is round or square, common in low-end watches, and a few high-end watches
