     The spring-driven clock introduced the truly movable timepiece and, with further innovations in miniaturization, the object that came to be called the watch.

In informal use, the presence of piece in the term timepiece causes many speakers to exclude large timekeeping devices such as wallclocks and grandfather clocks. In formal use, some speakers—particularly professional horologists and collectors—use the word clock to refer only to timekeeping devices that include a bell, chimes, or other mechanism to announce the passage of time. The term timepiece is then restricted to timekeeping devices (large or small) that lack such a mechanism.
