Ultra 606

66 views

10 1/2”’ | Hand Wind | Swiss Lever | Small Seconds | Date |

Remarks:

  • The Ultra 606 is an Ultra 602 with an additional date
  • Unusual: three bearing surfaces protruding beyond the edge of the movement on the dial side (as on the 602)
  • Date numerals 1 – 31 alternate between black and red
  • Very simple date setting:
    A finger on the hour wheel picks up a star-shaped date changing wheel every twelve hours. This has alternating short and long teeth. The finger advances both versions of the teeth, but only the long teeth advance the date disk every 24 hours
