10 1/2”’ | Automatic | Swiss Lever | Sweeping Seconds | Date | Day |

Remarks:

  • Automatic: hand winding possible
  • Date and day with quick setting
  • Balance bridge instead of balance cock
  • Ball bearing rotor
  • Rotor extremely small
  • The movement is probably based on a much smaller base movement, e.g. the Seiko 4206 with 7 3/4”’
