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 Astronomer Royal, Edmund Halley (c1656-1742) was a proponent of the Lunar distance method for determining longitude. The observations and calculations required for this method took many hours and were prone to error. The hand painted Moonphase dial (each signed and numbered by the artist) on the Moonphase model symbolises this alternative method.
The Moonphase Sea Clock (shown left)
Probably the most popular clock in our range of Sea clocks, the Moonphase Sea clock embodies 3 of John Harrison's basic principles used his original H1. It also provides in the Moonphase dial a representation of the competition (Lunar distance method) he faced for the solution to the Longitude problem back in the 18th Century.
The compound pendulums and Grasshopper escapement are positioned at the front of the clock making the subtle and almost silent "lock & release" of the pallets enduringly fascinating to watch.
Almost every piece is made in the workshops of Sinclair Harding using a combination of modern technology, materials and traditional finishing techniques. Every care is taken at each stage in the making and build to ensure that the final clock performs to a standard, which justifies the association with John Harrison.
All the brass parts are Gold or Rhodium plated and the steel parts made from a high grade stainless steel. The Standard base is made from an English Walnut frame, with a highly figured Burr veneer top, other options are Mahogany or Rosewood.
