| 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. Thomas Earnshaw style spring detent escapement with helical spring,
chronometer escape wheel. Chronometer wheel diameter 4 1/2", 4 second period.
Chronometer wheel driven by separate spring remontoire similar in design to that invented
by Tavan. 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. Click on photos for more details
