Usage notes

* Strictly, a timepiece is a timekeeping instrument that lacks a striking mechanism (e.g., a bell, chimes, or gong) to announce the passage of time. One with a striking mechanism is a clock. Although this traditional distinction is overlooked by some, it is commonly noted in dictionaries, glossaries of clock terms, and reference books on clocks, in addition to being widely maintained among knowledgeable collectors, major auction houses, horological museums, and watch manufacturers.
