John Harrison Sea Clocks
Our range of Sea Clocks are inspired by the great John Harrison. In each clock we have embodied at least three of the basic principles from Harrison's first Sea Clocks.
Perhaps his most well-known invention is the unique escapement, which gives the clock its popular name, 'The Grasshopper'. The subtle and almost silent 'lock and release' action of the pallets permits them to work without oil (and consequently be free of the effects of changes in viscosity) and at the same time make it so enduringly fascinating to watch.
The Invar pendulum are linked at the back, which allow the clock to function ‘out of level’. Their gentle action gives each clock that restful quality which is typical of an earlier more tranquil age.
For the standard Sea Clock two styles are available, they are named 'His' and 'Hers'. As with all Sinclair Harding clocks a selection of finish and base materials can be specified to make your clock a very personal piece.
