The word "clockwork" combines "clock" (from Old English clocca, meaning "bell," later evolving to mean a timekeeping device) and "work" (from Old English weorc, meaning "mechanism" or "labor"). Historically, it referred to the inner workings of mechanical clocks, which relied on gears and springs to function. Over time, it gained a figurative sense describing anything operating with mechanical precision.
