Glashutte ‘SPEZICHRON’ 22 RUBIS AUTOMAT NOS (New Old Stock) Day/Date. This model was the last completely new construction, the cal. 11-26, dubbed Spezichron. This movement with day/date cal.11-27 both had 28,800 beats per hour, 8 beats per second.
I am very pleased to have a NOS Spezichron example in my collection.
