What does horology mean?
Horology is the study and craft of measuring time, particularly through the design, construction, repair, and history of clocks, watches, and related instruments. The word combines elements meaning “hour” and “study,” reflecting the close relationship between the discipline and the measurement of hours. In academic or museum contexts, horology often means the history and technology of timekeeping devices; in workshop settings, it can refer more narrowly to the skilled practice of watchmaking and clock repair. The term is especially associated with precision engineering, mechanical ingenuity, and the traditional craft of producing accurate instruments. Although digital and atomic clocks have expanded the ways humans keep time, horology continues to be used for the specialist study and appreciation of both mechanical and modern timekeeping technology.

Where does horology come from?
Horology was formed in the early 19th century from the Greek hōra, meaning “hour,” and the combining form -logy, meaning “study of.” The underlying Greek word also contributed to English words such as hour and horoscope. Its modern sense developed alongside the study and manufacture of increasingly accurate clocks and watches.
