Hi,
I just wanted to share with you a picture of the movement of my "donor" watch, which I got in the mail this morning. Now, the movement in my original 6309-7040 seems fine right now, I just got this "donor" watch because it has something a little special, as you can see from the picture:

No, I don't mean the rust (yes I have noticed)!
It's the 6349A movement type. This is a variant of the 6309A with 23 jewels instead of 17. Where did the extra 6 jewels go? I have no idea, but I do intend to find out!
The donor watch is a vintage Seiko 5 that I fished on El Bayo for $18 plus shipping. I carefully scanned the various candidate watches available until I could find one with a relatively clean movement, and this one was it.
Cheers,
