CHRONOGRAPH MOVEMENT By AMERICAN WALTHAM CO. Actually SETS, and TICKS/RUNS (look at video in action). I can't get the chronograph to work or sweep second fly back to zero don't know how! , pusher (stem) won't go down.
Movement seems complete to me; but look at the pictures. Manual wind (stem wind, lever set) 14s (42.04mm dialeter), HUNTER type 13 jewels Adjusted Model 1874, Grade Riverside Made in Waltham, MA, USA Serial on movement #17997495, circa 1882 Original 12H single sunk porcelain dial, 41.4 mm, great condition, no hairline. All hands are there and seem original. It was stored for years in the watchmaker's cabinet.
