Notes

1965- Movements of this kind are not self-starting. So when pulling the crown, the balance is locked in a position, from which it reliably starts when pushing the crown (Fig.3). am/pm display by dot below/above date numeral (Fig.4) Attention: With once setting the hands back and forth, the date is only advanced half a day. So the date can be set at noon and midnight, but care must be taken that the dot is finally in the correct position (cf. above). signature often or always with Durowe number 880
