15 jewel 1925 (square) 10AP movement submitted by user shelton243. S/N 1.050.125
I have one with a box symbol for 1927. It's in an Illinois Watch Case Co. Stainless Back 1 1/2 L case that I assume is not original to the movement.
Thank you very much for the info.
I tried to follow your link and could not.
Can U please explain to me what mvnt SN 1047177.
I am a newbie at this so please be gentle.
My 3rd post today!
I just purchased a 1927 Conqueror with a 10AP 15 jewel movement missing a second hand is it possible someone knows which hands are interchangeable I can find no info anywhere.
updated 2012/03/22 to include 17 jewel w/ mvnt SN 1047177 located at:
note both triangle and arrow date code on movement?
End year for 10 AP entered as 1926 until other info is found/entered rather than leaving blank.
