Clock fit ups save time for clockmakers who intend to construct quality wrist watches without having to select parts from scrape and construct them. Clock fit ups are also called inserts, as well as the terms refer to a manufacturer-preassembled device that gets pressed comfortably right into an opening that is usually pierced in some type of case. This approach is especially appealing if one intends the framework to be the center of attention rather than the wrist watch itself.
