DW sizes?

[archibald]

I'm in the middle of sorting my parts bin, and I have a DW with a font I don't recognize--and I'm wondering what the hell it is. It measures about 23 mm on the outside w/ a 17.5 inner diameter. The print quality and general finish looks a lot like the 2824/36 & 7750 wheels I've seen, but the font makes me think Asian or maybe Sandoz. Does anyone know the measurements of ETA datwheels?

Are the teeth recessed or on the same plane as the rest of the wheel? 2836 == recessed teeth.

The teeth are recessed...but I have a known asian 21J datewheel that also has recessed teeth. Are the asian 21J DW's the same size as 2824/36 DW's?
