The minute repeater's operation involves several key components that work together harmoniously.

Key Components

Chiming MechanismConsists of gongs and hammers to produce sound.
Slide LeverThe activation lever located on the watch case, used to start the mechanism.
Centrifugal GovernorRegulates the speed of the chimes, ensuring consistent timing.

Step-by-Step Process of Activation and Chime Production

  1. Activation: The wearer slides the lever along the side of the watch case, winding a small spring that stores potential energy.
  2. Energy Storage: The spring captures and holds the energy required to drive the chiming mechanism.
  3. Initiation: The centrifugal governor ensures the hammers strike the gongs at evenly spaced intervals, producing a clear and consistent sound.
  4. Chiming Sequence:
    • Hours: The mechanism chimes the hours first, with one chime for each hour.
    • Quarter Hours: It then uses a distinct combination of chimes to signal the quarter hours.
    • Minutes: Finally, single chimes indicate the number of minutes past the last quarter hour.
