How to Find Out How Old a Clock Is

Determine what kind of clock that you have by consulting pictures of different clock styles in an illustrated glossary (see Resources). Categorize your clock into one general classification, such as shelf, wall or longcase clock.

List all of the stylistic features of your specific clock, including the materials, dials, hands and settings. Research under the general classification and break it down into a more specific type using the information you have.

Consult a horological chronology to get a rough idea of when your particular style of clock was first made (see Resources).

Locate the name of the maker of the clock. Look for it printed or engraved on the dial face. Conduct thorough research on the maker's name, trademarks or any trade names you find present.

Look to see if your clock has a serial number, usually stamped on the back plate of the movement. Use this as a handy clue when researching your clock's age.

Inspect your clock's parts for patent numbers. Patent numbers can give you an idea of the earliest possible date an item marked with a patent date could have been made, allowing you to estimate a clock's age.
