Uhrmacherei-Set nach dem vorstehenden Anspruch, dadurch gekennzeichnet, dass die Vorrichtung zum Erzeugen mindestens einer Frequenz angeordnet ist, um weiter ein zweites periodisches Signal mit einer Frequenz FINF erzeugen zu können; dadurch, dass die Steuereinheit (30) angeordnet ist, um dem Magnetfeldgenerator (28), wenn die bestimmte Korrektur einem Vorgang in der angezeigten Zeit, deren Korrektur vorgesehen ist, entspricht, ein zweites Steuersignal, das von dem zweiten periodischen Signal abgeleitet ist, während einer zweiten Korrekturperiode bereitzustellen, um das Korrektursystem derart zu aktivieren, dass dieses Korrektursystem eine zweite Reihe von periodischen Bremsimpulsen erzeugt, die von der mechanischen Vorrichtung mit der Frequenz FINF auf den mechanischen Resonator (12) angewendet werden, wobei die Dauer der zweiten Korrekturperiode, und damit die Anzahl der periodischen Bremsimpulse in der zweiten Reihe durch den zu korrigierenden Vorgang bestimmt werden; und dadurch, dass die Frequenz FINF vorgesehen ist, und die mechanische Vorrichtung derart angeordnet ist, dass die zweite Reihe von periodischen Bremsimpulsen mit der Frequenz FINF während der zweiten Korrekturperiode eine zweite synchrone Phase erzeugen kann, in der die Oszillation des mechanischen Resonators auf eine Korrekturfrequenz FlCor synchronisiert wird, die niedriger ist als die für den mechanischen Oszillator vorgesehene Sollfrequenz F0c.
  8. Uhrmacherei-Set nach Anspruch 6, dadurch gekennzeichnet, dass die mechanische Vorrichtung angeordnet ist, um weiter den mechanischen Resonator unter der Wirkung eines vom Magnetfeldgenerator (28) erzeugten Magnetfelds, das auf das bewegliche magnetische Element angewendet wird, blockieren zu können, um eine Oszillation des mechanischen Resonators während einer Korrekturperiode vorübergehend anzuhalten; und dadurch, dass die Steuereinheit (30) angeordnet ist, um, wenn die bestimmte Korrektur einem Vorgang der angezeigten Zeit entspricht, dem Magnetfeldgenerator ein drittes Steuersignal bereitzustellen, damit dieser die mechanische Vorrichtung derart aktiviert, dass letztere die Oszillation des mechanischen Resonators während der Korrekturperiode, die durch den zu korrigierenden Vorgang bestimmt wird, blockiert, um den Gang des Antriebsmechanismus während dieser Korrekturperiode anzuhalten.
  9. Uhrmacherei-Set nach einem der vorstehenden Ansprüche, dadurch gekennzeichnet, dass die Steuereinheit (30) einer elektronischen Vorrichtung zugeordnet ist, um eine vorzunehmende Korrektur zu bestimmen, welche die bestimmte Korrektur an einem gegebenen Datum oder in Abhängigkeit von der von der Uhr angezeigten aktuellen Zeit definiert.
  10. Uhrmacherei-Set nach Anspruch 9, dadurch gekennzeichnet, dass die Stütze ein Kästchen, eine Schatulle oder ein Verkaufsständer ist; dadurch, dass die Stütze die elektronische Vorrichtung zur Bestimmung einer vorzunehmenden Korrektur umfasst, wobei diese elektronische Vorrichtung eine fotografische Vorrichtung (40) umfasst oder dieser zugeordnet ist, die einen aus einer Matrix von Fotodetektoren gebildeten fotografischen Sensor umfasst; dadurch, dass die elektronische Vorrichtung eine Bildverarbeitungseinheit umfasst, die angeordnet ist, um die Position mindestens eines bestimmten Zeigers der analogen Anzeige (10) in einem von der fotografischen Vorrichtung aufgenommenen Bild bestimmen zu können; und dadurch, dass die elektronische Vorrichtung eine Zeitbasis umfasst oder dieser zugeordnet ist, die in der Lage ist, eine präzise aktuelle Zeit bereitzustellen, und weiter eine Vergleichseinheit umfasst, um die vorzunehmende Korrektur zu bestimmen.
