What is a marine chronometer?

A marine chronometer is an ultra-precise timepiece used historically for calculating longitude at sea. Unlike standard clocks, they are mounted on gimbals to stay level and maintain accuracy despite a ship's movement.

How do I mount a bulkhead clock?

Bulkhead clocks are designed to screw directly onto walls through pre-drilled holes in the brass flange or case. Ensure you use appropriate fixings for your wall type, as these brass and glass pieces can be surprisingly heavy.

What is a fusee movement?

A fusee movement uses a conical pulley and a chain to regulate the pull of the mainspring. This clever mechanical device ensures the clock receives even power as the spring runs down, improving accuracy.

How do I wind a marine clock?

Most antique marine clocks require a matching winding key inserted into the dial face or movement back. Turn the key gently until you feel resistance, taking care not to overwind the mainspring.

Are these clocks water resistant?

While built for damp marine environments with sealed glass bezels, antique clocks are not waterproof. Keep them away from high-moisture areas in the home to protect the internal brass and steel components.
