    I was wondering if there is anyway to verify from the watchhead itself if my Speedy is a 3570.50 or 3590.50?
    Here's a pic of its movement

    Given the finishing of the 861 movement, I am inclined to think it is a 3590.50 but I am getting confused by all the literature I read off the internet.
    Any input will be greatly appreciated.
    TIA!

    If I see the serial # correctly (4835...) that would suggest PIC 3570.50
