  • Hour Hand: Shorter hand showing the hour.

  • Minute Hand: Longer hand showing minutes.

  • Second Hand: (Optional) Thin hand showing the passing seconds.





5. Weights



  • What They Are: Usually three cylindrical metal weights.

  • Function:

    • One powers the timekeeping mechanism.

    • One powers the chime.

    • One powers the strike that sounds the hour.



  • Operation: Slowly descend over time and must be wound weekly.





6. Chains or Cables



  • What They Do: Connect to the weights and allow winding.

7. Pendulum



  • What It Is: A long rod with a circular or disc-shaped bob at the end.

  • Function: Regulates the clock’s movement with its back-and-forth motion.

  • Adjustment: Can be fine-tuned to correct timekeeping (up for faster, down for slower).





8. Clock Movement



  • What It Is: The inner mechanical system that powers the clock.

  • Types:

    • Mechanical: Powered by weights and gears.

    • Quartz: Battery-powered with fewer moving parts.



  • Parts Inside: Includes gears, levers, escapement, and chime hammers.





9. Chime Rods and Hammers



  • Chime Rods: Thin metal rods that create sound when struck.

  • Hammers: Small arms that strike the chime rods.

  • Chime Types: Westminster, Whittington, St. Michael, and more.





10. Escapement Mechanism



  • What It Is: A gear-and-lever system that works with the pendulum.

  • Function: Controls the release of energy in timed intervals, allowing precise ticking.





11. Trunk (or Waist)



  • What It Is: The central section of the clock, usually elongated.

  • Features: Houses the pendulum and weights; often has a glass door for visibility.

  • Decorative Element: Wood grain, carvings, and brass accents enhance its beauty.
