Thanks for the link....but unfortunately, I've already spent an hour or so checking out all the Alpina movements on the site - nothing matches. I've been told that the movement in mine is a 13 ligne Alpina - but no one seems to have any info on Alpinas that are as old as this one appears to be. The marque goes back to pre-WWI, and all the info I've found deals with much more recent watches and movements. Frustrating, to say the least........
