The electromechanical caliber 7806A is a very good movement of the heyday of electromecianical movements.
The balance, which is beared in two inhouse Parashock protection systems carries two magnets, which drive and are driven by a coil. This coil is switched by a transistor and therefor needs no electrical contacts. It makes the balance beating always with the same strength, which results in a high accurancy. With the excenter fine tuning system, you can excellently regulate it.
The caliber 7086A has got a day and weekday indication, which advances slowly. The quickset mechanism, however, is simple and genious together: The lever at “6”, which reminds of a hammer, advances either the day or the date by pressing the crown, depending, on whether the “12” or the “6” of the watch is up.
