This tool is only suitable for pressing the bottom bottom cover. If you want to open the revolving bottom cover, please use a two-leg or three-leg opener.
How to use: Put the prying knife in the special prying opening and tilt it outwards.
How to prevent slipping: please wrap the watch with a piece of cotton cloth to prevent slipping in your hands. You can also put a piece of tape on the edge of the knife to prevent slipping and flower the bottom cover!
There are usually three types of watch back covers:
1. Tooth bottom(The bottom cover is made up of tiny teeth). This kind of bottom cover must be round bottom, with good waterproof performance. High-end watches such as Rolex, Tudor, etc. are such back covers.
2. Screw bottom(There are usually 6 small notches on the bottom cover, very few only have 2 small notches). This type of bottom cover must be round bottom, and mid-to-high-end watches generally use this type of bottom cover.
3. Ordinary bottom (usually there is a small special pry opening in the 7-character 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 kind of bottom cover is round bottom or square bottom, which is common in middle and low-end watches, and can also be seen in a few high-end watches.
