AS 1978-2

26 views

5 3/4 x 6 3/4”’ | Hand Wind | Swiss Lever | No Seconds |

Remarks:

  • In principle, the AS 1978-2 is a 1977-2 with a rounded edge on the left and right instead of a straight edge
  • Differences between AS 1978 and AS 1978-2:
    Apart from the number of jewels (21 vs. 17) none recognizable. The three slits on the crown and ratchet wheel screws are not present on all 1978-2s, so they are not a distinguishing feature
