  5. Chronographen-Mechanismus nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass die Koordinationseinrichtung (60) ein erstes Säulenrad (640a) umfasst, um den Zustand der ersten Bremse (50a) aus zwei entgegengesetzten Zuständen zu wählen, nämlich die inaktive und aktive Zustände der ersten Bremse (50a), sowie ein zweites Säulenrad (640b), um den Zustand der zweiten Bremse (50b) aus zwei entgegengesetzten Zuständen zu wählen, nämlich die inaktiven und aktiven Zuständen der zweiten Bremse (50b), wobei jedes Manöver des ersten Säulenrads (640a) um einen Schritt, kehrt den Zustand der ersten Bremse (50a) um, jedes Manöver des zweiten Säulenrads (640b) um einen Schritt, kehrt den Zustand der zweiten Bremse (50b) um, die erste und zweite Säulenräder (640a, 640b) sind um einen Schritt relativ zueinander phasenveretzt, so dass um die erste und zweite Bremsen (50a, 50b) in entgegengesetzte Zustände zu bringen, die Steuerung (P1, P2, P3, 60, 701-714) eingerichtet ist, um die erste und zweite Säulenräder (640a, 640b) zusammen in einem Schritt zu betätigen, wenn gefordert ist, die Konfiguration der ersten und zweiten Bremsen (50a, 50b) zwischen der ersten und zweiten Konfigurationen umzukehren.
  6. Chronographen-Mechanismus nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass die Koordinierungseinrichtung (60) eingerichtet ist, um die erste und zweite Bremsen (50a, 50b) in drei alternativen Konfigurationen zu halten, nämlich der ersten Konfiguration, der zweiten Konfiguration und einer dritten Konfiguration, in der die erste und zweite Bremsen (50a, 50b) in ihren jeweiligen inaktiven Zuständen sind, so dass die erste und zweite Sekundenzeiger-Drehteile (30, 35) frei drehen können.
  7. Chronographen-Mechanismus nach Anspruch 2, dadurch gekennzeichnet, dass die Steuerung (P1, P2, P3, 60, 701-714) weiter umfasst:
    - Einen ersten Steuerungsmechanismus (P1, 701-705), um eine erste manuelle Anweisung in eine erste Betätigung umwandeln zu können, welche den Zustand der Kupplung (40, 401, 402) zwischen seinen eingekoppelten und ausgekoppelten Zuständen umkehrt, und
    - Einen zweiten Steuerungsmechanismus (P2, 711-714), um eine zweite manuelle Anweisung in mindestens eine zweite Betätigung umwandeln zu können, welche die Konfiguration der ersten und zweiten Bremsen (50a, 50b) zwischen ihren ersten und zweiten Konfigurationen umkehrt.
  8. Chronographen-Mechanismus nach Ansprüchen 4 und 7, dadurch gekennzeichnet, dass der zweite Steuerungsmechanismus (P2, 711-714) die zweite manuelle Anweisung in zwei Betätigungen umwandeln kann, nämlich der zweiten Betätigung und einer dritten Betätigung, welche der zweiten Betätigung folgt und den Einholmechanismus (42) veranlasst, im Flug den Zwischenchronographen-Drehteil (20) auf null rückzustellen, es sei denn, dass der Zwischenchronographen-Drehteil (20) bereits bei null ist.
  9. Chronographen-Mechanismus nach Anspruch 8, dadurch gekennzeichnet, dass die Steuerung (P1, P2, P3, 60, 701-714) eine dritte manuelle Anweisung in eine dritte Betätigung umwandeln kann, ohne die zweite Betätigung zu veranlassen.
  10. Chronographen-Mechanismus nach Anspruch 7, dadurch gekennzeichnet, dass der zweite Steuerungsmechanismus (P2, 701-711, 713, 714) die zweite manuelle Anweisung in die zweite Betätigung umwandeln kann, ohne eine dritte Betätigung zu veranlassen, welche die Null-Rückstellungsvorrichtung (41, 410-415) veranlasst, den Zwischenchronographen-Drehteil (20) auf null rückzustellen.
  11. Chronographen-Mechanismus nach Anspruch 6 und jedem der Ansprüche 7 bis 10, dadurch gekennzeichnet, dass der erste Steuerungsmechanismus (P1, 701-705) die erste manuelle Anweisung (P1) in zwei Betätigungen umwandeln kann, nämlich der ersten Betätigung und einer anderen Betätigung, welche die erste und zweite Bremsen (50a, 50b) in die dritte Konfiguration bringt, es sei denn, die erste und zweite Bremsen (50a, 50b) befinden sich bereits in der dritten Konfiguration, während die zweite Betätigung die erste und zweite Bremsen (50a, 50b) aus der dritten Konfiguration bringt, es sei denn, die erste und zweite Bremsen (50a, 50b) sind bereits in einer der ersten und zweiten Konfigurationen.
  12. Chronographen-Mechanismus nach einem der Ansprüche 7 bis 11 und einem der Ansprüche 3 und 4, dadurch gekennzeichnet, dass die Steuerung (P1, P2, P3, 60, 701-714) eine dritte manuelle Anweisung in eine dritte Betätigung umwandeln kann, welche die Null-Rückstellungsvorrichtung (41, 410-415) veranlasst, den Zwischenchronographen-Drehteil (20) auf null rückzustellen, es sei denn der Zwischenchronographen-Drehteil (20) ist bereits auf null.
  13. Uhr, umfassend ein Uhrwerk (15) und mindestens ersten und zweiten Sekundenzeiger (6, 7),
    dadurch gekennzeichnet, dass ein Chronographen-Mechanismus (10) gemäss einem der vorhergehenden Ansprüche umfasst ist, wobei dessen Zwischenchronographen-Drehteil (20) einen Antrieb des Uhrwerks (15) aufnehmen kann, wobei die erste und zweite Sekundenzeiger-Drehteile (35) jeweils den ersten (6) und den zweiten Sekundenzeiger (7) tragen.
