    COSC movement

    I have been looking at the flieger and marine model.

    On the cheaper models in these ranges, like the Flieger automatic and Marine automatic a chronometer certified (COSC) movement is one of the options.

    If you chose the more expensive models, however, like the Marine Original or Flieger original, there is not this option:

    Now to my question:

    1: Are the movements on the more expensive models already chronometer certified, or are they as excact as chronometers?

    2: If not why is not this option on the more expensive models?

    Hope to hear from you!

    The movements on the MO and FO are not COSC certified, but provide excellent running qualities due to the swan neck fine adjustment and the screw balance.

    The movements are quite different, MO and FO are fitted with handwinding Unitas movements, the Flieger and Marine are fitted with ETA 2824-2 movements, only with these models you can opt for a COSC certified movement.
