The BM11900 is a full calendar movement with moonphase complication, based on a Sellita SW300-1 paired with a Dubois Dépraz 9000 calendar module. This combination provides day, date, month, and moonphase indications. The Sellita base provides a reliable and serviceable foundation while the DD module adds the calendar complications commonly found in Classima models with full calendar functions.
