Repeating watch

Source : Webster's Revised Unabridged Dictionary (1913)



   {Repeating instruments} (Astron. & Surv.), instruments for
      observing angles, as a circle, theodolite, etc., so
      constructed that the angle may be measured several times
      in succession, and different, but successive and
      contiguous, portions of the graduated limb, before reading
      off the aggregate result, which aggregate, divided by the
      number of measurements, gives the angle, freed in a
      measure from errors of eccentricity and graduation.

   {Repeating watch}. See {Repeater}
