Maker, E. Dent, London, England, c.1970's. Movement
16"h x 11"w x 6"d excluding base and case. Another nice example from this
quality clock maker. William Hardy balance wheel with helical spring,
chronometer escape wheel. Chronometer wheel diameter 4 1/2", 4 second
period. Chronometer wheel driven by complex, separate spring remontoire invented
by William Hardy. Everything about the escapement is
huge and robust. Escape arbor rides in roller bearings. Due to the large mass of the
chronometer wheel and it's spring in addition to the remontoire, there is a greater demand
for power. Employed are a pair of spring barrels; each having two springs. This clock was
made as a sister piece to
another chronometer model by
the same firm to show off details of the chronometer escapement, but was a
much more expensive and therefore rarer model. Click on photos for more details
