    swatch ETA movements

    hello everybody
    does any one know what is the model of the ETA movement in swatch irony the chrono series (the big irony) (mine is yos403)
    i found ETA chrono movemnts with 4 jewels but the measure 29.8mm (ETA G10.211,ETA G10.711, ETA G10.791) but i think mine should be bigger
    and also what is the ETA movement in the irony retrograde series? i found this:(G15.261
    ) but it has 6 jewels and it is mentioned on the watch's bak that it has only 4 jewels!!

    thank tou all

    Why do you think your movement should be bigger?

    The YRS Swatch watches use a G15.261 that is made just for Swatch watches, they are slightly cheaper, hence the reduced jewel count.

    i think mine is bigger since the my case diameter is about 47mm
    can i replace the movement in the retrograde with the G15.261?will it fit?

    There are thousands of watches with huge cases and smaller movements....that's why they invented case spacer rings.

    And, a 13.25''' movement (31.75 mm) is larger than average movement, altough quite typical for a chronograph.

    (BTW it does use a G10....)

    It's the same movement, it just has a few plastic bearings in place of jewels.

    A YOS403 should have a G10 in it....

    thank you veryy much :) but there is a small issue i searched for the g15.261 that u told men it is in the irony retrograde and i found that the retrograde hand (the stop watch hand) oscillates in anti-clock wise path !!!!!! while the irony retrograde movement is normal so, is the oscillation direction controllable? or the irony retrograde has another movement??
    sorry for my many questions :)

    This is an information page about the G15.261.

    It looks like you're right, watches based on the G15.261 seem to have a central retrograde seconds hand that rotate counterclockwise.

    so ! this isn't the movement on the irony retrograde ? or is it easy to reverse the movement? by changing the circuit direction for example?

    so, do you think that the irony retrograde has a different movement model??
