How does a moon dial work?

The mechanism connects to the clockwork via a gear train that rotates a double-moon disc once every fifty-nine days. This movement tracks the synodic lunar month behind an arched aperture on the dial face. As the internal wheels turn, the painted moon phases slowly advance across the opening. This mechanical calculation allows the clock to display the exact appearance of the moon outside.

Where were these clocks made?

Provincial clockmakers across Britain constructed these timepieces in workshops spanning from Lancashire and Cheshire to Scotland and Wales. Local craftsmen built the movements while regional cabinetmakers fashioned the tall wooden cases. Towns such as Liverpool, Manchester and Birmingham produced many notable examples signed on the dial face. This regional diversity means each clock carries distinct local stylistic traits.

How do I wind an eight day clock?

An eight-day movement requires winding once a week by inserting a key into the winding holes on the dial face. Turning the key slowly lifts the internal weights suspended inside the trunk of the case. Care must be taken not to overwind the movement or let the weights drop too suddenly. Regular winding keeps the pendulum swinging and ensures the lunar mechanism stays synchronised.
