An automatic is a mechanical watch whose mainspring is wound automatically step by step by the natural motion of the wearer’s arm by means of a rotor. A slipping clutch device is used to prevent an overwinding of the spring, when the watch is already fully wound up. Automatic watches are not only outstanding because of their easy handling, but one further advantage is, that the constant tension of the mainspring provides a remarkable even running of the watch.

The indication “waterresistant” means splashproof. Watches with this indication on the case back are NOT waterproof ( that means NOT suitable for shower, swimming or diving). Only watches with the indication 10 ATM ( 100m ) are suitable for swimming and respectively watersports. The water resistance degree for diving watches is 20 ATM ( 200m ). These watches are suitable for diving ( scuba diving ).

The indication for size and characteristic forms of movement, as well as the arrangement of plate, bridge, cock, barrel and escapement.

Als Gangreserve oder Gangautonomie bezeichnet man die Zeitdauer, in der das (vollständig aufgezogene) Uhrwerk noch läuft, nachdem die Uhr das letzte Mal bewegt wurde. Sie ist je nach Werk unterschiedlich und beträgt zumeist etwa 35 bis 60 Stunden.


The power reserve is designed to show the amount of remaining autonomy, that means how much time the ( fully wound watch ) will keep running autonomously after the clock has been moved the last time. The power reserve is varying, depending on the kind of movement. Usually it lasts about 35 up to 60 hours.

Each of these clocks is subjected to a series of quality tests by our clockmakers just prior to its delivery. So any quality mistakes are nearly impossible!
