Lugs are the small metal protrusions on the sides of a watch case that the watch band or bracelet connects to. The shape of the lugs varies depending on the style of the watch, and can come in a variety of sizes. They are usually made from stainless steel, but can also be made from other metals such as gold, titanium, or ceramic. Lugs provide a secure connection between the case and strap, ensuring that the watch remains firmly in place on the wrist.
