    Hi all,

    Trying to source a movement for my cosmic. My cosmic has a Cal 1020 and wondering if a caliber 1021 would fit?

    Thanks!

    The 1021 is the 23 jewel version of the 1020, so other than that, they are the same. However you would need the correct height for the watch as these come with different lengths for cannon pinion, hour wheel, and seconds pinion.
