HOROLOGY

Description

G04 covers the design, construction, and operation of devices for measuring and indicating time. This includes mechanical and electronic clocks, watches, chronometers, timing mechanisms, and related apparatus such as pendulums, escapements, and balance wheels. The class also encompasses time-measuring instruments used in scientific and industrial applications, as well as apparatus for controlling or synchronizing time-dependent processes. Excluded are general timekeeping methods (classified in other IPC sections) and electronic display systems not integral to the timekeeping mechanism itself.
