You guys are going crazy with a caliber database, so I figured I should try to carry my own weight.

Here's a relatively uncommon one, the 17 jewel Watch Specialties Co. caliber 647. I'm guessing it was in use from the late teens to early twenties. I think my ID as Record 022K is solid. The distinctive bridges and setting parts seem identical to me. The 647 shows up as a movement option for plate 23-B (Strap 1 style) in the 1918 book, but the case is more like the 23-C with conventional lugs.

This example has a serial number of 858749 and in a sterling case with a serial number 567414. I'm guessing the case was Cincinnati made. It doesn't have any Swiss or other markings.

For any further information, I think you can ask timeliz. I'm reasonably confident I sold it to her!

You did.
Funny, I was intending to post this one last night. Got sidetracked.

Here's a straight on pic of the mov plates:
