Before 1577, clocks were missing a reliable way to keep time accurately. Early mechanical clocks relied on the swing of a pendulum, but this method was highly susceptible to changes in temperature and air pressure, making it unreliable.
Before 1577, clocks were missing a minute hand. The first clock with a minute hand was created in 1577 by Jost Bürgi, a Swiss clockmaker. This invention allowed for more precise timekeeping and was a major advancement in clock technology.
