1932 Kirkwood I believe
Another ad similar time period which said "15 jewel", and I think some panel members were "tentative" on an example in our database based on the jewel difference.
Gary's 1931 is 15 jewels. Barry G's 1931 is 17 jewels. Possible design change a little later- ad for Kirkwood. Dec 20 1934 edition of The Gettysburg Times. Click for full ad.
I'm good with tentative Kerkwood for subject watch!
Jabs. Looks like the center wheel jewel is missing from it's cap. This may give quite a bit of play in the center wheel. Check the opening size where the pinion sticks through. It's bigger than it would be in the jewel (if present). You may wanna have the jewel replaced before you run this one.
17 jewel watches should be jewelled straight through to the center wheel. A 15 jewel watch won't have the centre wheel jewelled, but will rather have a brass setting, or simply a hole in the plate with an oil sink. Chatons are brass settings holding jewels, and may be pressed in, or in older watches, held in place by three tiny screws.
I think what we're seeing here is jus a reflection of light on the centre jewel?
