Remark

Junghans 653.04; Durowe 7528; Collection: Bernhard Schmotte

Offered were two models, a variant with oval stainless steel case and bright dial and one in a gold-plated, square case. The second variant was used in the same way by other companies, including the French watch company LIP. The date and the monthly calendar indication can be conveniently switched through the crown. In crown position 1, turning it clockwise: date setting, turning counterclockwise: setting the monthly calendar. The calendar indication does not automatically switch on after one month but must be switched manually, then the respective weekday in the monthly overview can be read. The case of the square version shows an interesting attachment of the back cover: A small embossed note near the housing edge on the back indicates that the tape should be removed. Between the lugs there are two small screws that secure the lid.
