    Hi Sam,
    Welcome to the forum. You'll get to learn lots here.

    There is no such thing as a ETA 28724-2 movement. Wherever you saw that, it must have been a typo. Stowa uses the 2824-2, so there are no photos depicting one against the other. The 2824-2 is well documented - try using the search function on this forum and you'll have plenty to see!

    Don't forget, once you have the watch on your wrist, images are a must, so we can enjoy it with you!

    Happy New Year

    Glen

    Like the Airman Automatic, except for the date display at the 6 position. The dial is black, the blued hands are filled with Superluminova, and the white Arabic numerals and markers also luminescent. The movement, housed in a matt casing, is an ETA 28724-2 with 25 jewels and an engraved rotor that can be viewed through the sapphire crystal display back. The Airman Automatic comes with a riveted or unriveted leather strap fitted with a matt STOWA buckle. For a more authentic look, we suggest the riveted strap.

    i searched it
    that means a typing error?
    If so, then y do i hv to add $177 to become a same movement???
    Or, It has different between them??
    thx Glen

    Each Airman has its own price due to the dial differences and the no-logo uses a silver rotor and decorated blue screws, and if you want to top it off with a COSC movement. However, they are all 2824-2. I can guarantee that one...

    No - all ETA movements are Swiss Made, there is no ETA made in Germany and there never has been one.

    This is one of your first posts here and you may not know that we offer a cross-forum-search-function. Typing ETA 2824 will lead you to a bunch of threads/posts.

    Sources you may look at: wikipedia, www.eta.ch.

    Shortly: There are 4 grades of ETA 2824-2 movements offered by ETA:

    Standard and Elaboré:
    Mainspring - Nivaflex NO
    Shock protection - Etachocs
    Pallet stones - Polyrubies, Epilame-coated
    Balance - Nickel gilt
    Balance staff - Epilame coated
    Collet - Nivatronic
    Hairspring - Nivarox 2
    Hairspring heat treatment - Etastable

    Top and Chronometre:
    Mainspring - NivaflexNM
    Shock protection - Incabloc
    Pallet stones - Red rubies, Epilame-coated
    Balance - Glucydur gilt
    Balance staff - Epilame coated
    Collet - Nivatronic
    Hairspring - Anachron
    Hairspring heat treatment - Etastable

    The performance differences are the big differences between the various grades: ("The limit values are subject to interpretation: 95% of the pieces delivered in a lot must be within the specified limits.")

    Standard:
    2 positions (CH, 6H)
    daily rate: +/-12 sec/day
    Maximum positional variation: 30 sec
    Isochronism (between 0 and 24 hours): +/- 20 sec

    Elaboré:
    3 positions (CH, 6H, 9H)
    daily rate: +/-7 sec/day
    Maximum positional variation: 20 sec
    Isochronism (between 0 and 24 hours): +/- 15 sec

    Top:
    5 positions (CH, FH, 6H, 9H, 3H)
    daily rate: +/-4 sec/day
    Maximum positional variation: 15 sec
    Isochronism (between 0 and 24 hours): +/- 10 sec

    Chronometre:
    As per COSC specifications, which as far as most owners will notice, isn't much different from Top grade.
    For COSC see: www.cosc.ch
