Every half hour, the 70 centimeter wall clock Classica S 70 (black) from Erwin Sattler makes its presence felt with wonderfully harmonious sounds. However, it does not keep its owners waiting. Thanks to the possible repetition, the strike train can be triggered manually up to the fiftieth minute. This triggers the strike train and the past hour strikes once again. For a quiet living environment, it can also be switched off completely.
