Progressing on from my hybrid quartz/mechanical work this is a wholly mechanical version of Isochronal, where the pendulum dictates the rate of the clock. Up to this point I had reservations about the timekeeping ability of the work given I really push strict escapement geometries for visual effect. The result has been quite surprising with rates around 10 sec error per day.
The escapement is a sculptural variation on the Grasshopper escapement invented by the British clockmaker John Harrison around 1722 and used in several of his famous sea clocks. The battery driven winding system which rewinds suspended magnetic balls is automatic and operates every 2.5 minutes.
The dial for this clock was made in the traditional manner, by engraving the numerals into the surface and filling with an encaustic wax.
