Bolt is a watch term that refers to the type of clasp found on certain watches. It is a metal clasp that is shaped like a bolt, with a head and a threaded shaft. The head of the bolt is connected to the watch case, while the threaded shaft is threaded into the strap or bracelet, securing it to the watch. The bolt clasp is often found on luxury watches, providing a more secure fit than a traditional buckle clasp.
