How do moon dials work?

A toothed wheel connected to the motion work rotates a disc twice during each lunar month to track the phases. The painted dual moons disappear and reappear behind curved horizons on the dial arch to indicate the current phase.

Where were these clocks made?

Makers across regional British towns and cities produced these timepieces during the Georgian and Victorian eras. Provincial clockmakers sourced local timber while ordering specialised painted dials from urban centres.

How do I set the moon phase?

Owners advance the lunar disc manually using fingers or a small tool according to the current calendar moon. The mechanical gear train then maintains the cycle automatically as long as the clock remains wound.

What is an eight day movement?

An eight day movement requires winding via the dial winding holes once every week using a crank key. This system uses two suspended weights rather than the shorter daily drop found in thirty-hour clocks.
