Mantle clocks can have quartz movements or can be traditional key wound clocks. Decorative clocks can include brass, glass and various wood finishes including inlays. Carriage mantel clocks have a small handle on top. Many mantle clocks chime. Traditional, wound mantle clocks' time is regulated either by moving the pendulum disk up or down, if the clock has a pendulum, or they are regulated by moving the time adjustment lever.

Skill level:


  1. 1

    Pick a time that you'd like to check your clock over a six-day period. It should be the same time each day.

  2. 2

    Write down the time you have selected.

  3. 3

    Check the correct time using a known source, like a radio station's on-the-hour beeps.

  4. 4

    Re-set the minute hand on the mantel clock to this time.

  5. 5

    Check the correct time on day two, and compare it with the time shown on the clock.

  6. 6

    Adjust the time on the clock if the clock is fast or slow. For clocks with a pendulum, move the disk up or down by turning the adjustment nut. Turn the nut to the left to slow the clock down and to the right to speed it up. One revolution equals a half a minute. If the clock doesn't have a pendulum, use the adjustment lever on the back of the mechanism. Move the lever towards the minus mark to slow the clock and towards the plus mark to speed it up.

  7. 7

    Repeat for days three through six if necessary.
