Good video of an Earnshaw Chronometer escapement in action. This highly accurate and popular chronometer escapement has found its way into high quality watches. carriage, skeleton and other clocks and many ships chronometers and remains one of the most accurate escapements of all time.  Earnshaw’s escapement encompasses the detent  which he modified into a spring detent rather than pivoted detent.  Although his employer patented the spring detent Thomas Earnshaw is credited as being the designer of this improvement.  It has become the most used escapement in marine ships chronometers and is beautiful to watch in action.  It’s well known as the Earnshaw chronometer escapement or Earnshaw standard chronometer spring detent escapement. It is a none friction escapement with impulse in one direction of the balance only.
