Screw

Watch screws are small but essential components used to secure bridges, plates, dials, movements, cases, bracelets, and many other parts. They come in different sizes, shapes, threads, and finishes depending on the watch and movement. Screws are frequently replaced when lost, stripped, rusted, broken, mismatched, or damaged during servicing and restoration work.
