are a small component of a watch and are used to hold the case and bracelet together. Typically, these screws are made of flat or cross-shaped metal. They are a vital part of watchmaking. They are made in a variety of sizes and are available in various types. Some screws are used on the dial, while others are used for fixing the winding wheel or regulator spring.
Watch Screws are made of metal and have a locking mechanism. This prevents operational errors and improves the water-resistance of the watch. The crown can also be adjusted easily by unscrewing it counter-clockwise. To do this, you need to unscrew the screw down crown first, and then pull it to the desired position. Then, re-lock the screw to secure the crown.
Some watchmakers use a chemically-blued screw while others use painted screws. The key purpose of bluing the screw is to increase the hardness of the metal. The initial hardening process makes the part too hard, and watchmakers must temper it to soften it. This step is time-consuming and requires a high degree of expertise.
If your watch is equipped with a screw back, you may be able to remove the case by opening the back with a watch case wrench or a watch holder. In some cases, you may need a friction ball or pliers to open the screw back. However, it is important not to over-stretch your watch when opening it. It can cause damage to the backing piece. If this happens, you may have to replace it. You may also be able to use a friction ball or pair of scissors to help with this task.
While a screw-down crown offers greater security for a watch, a push-pull crown allows the user to access and operate it without the use of a tool. This makes them convenient for everyday wear and can also protect the watch against accidental operation. Unlike Screw-down crowns, the pull/push crown allows the watch to be worn in the water for extended periods of time. And while the conventional crown is less secure, it does seal a watch up to 200 meters.
