This is a Bulova Ladies watch in 10 KT Rolled White Gold (White) with a cuff bracelet marked
M2 on back case - Movement marked M3.
I believe this is part of the American Girl or possible Canadian Girl series???
I never have found any ads of this watch.
This is from a 1963 ad on the watchophilia site. Looks like a good match.

1962 Bulova American Girl "P"
Yes, I found the ad too from, Watchophilia.com, courtesy of Bob Butler.
Now the watch has a true name and variant.
I hit 1952 instead of 1962, having long nails is bad for typing. We all make mistakes.
1962 Bulova American Girl P
1964 Pricelist shows variant P with model number 33200, and also variant Q with number 33201. List does not state case color, but earlier 21-jewel diamond models using these variants had P-Yellow and Q-White. It would seem that this white gold version is likely the Q variant, but not enough to really validate that. I am tentative with either of the variants.

Thank you, Ken for the information regarding the difference between the "P" and "Q" variants, it is greatly appreciated.
With this info I believe it to be the "Q" based on your price list VS the ad due to the ommission of yellow or white gold in ad.

I think it is probably Q as well based on the price list but do find it interesting that the Miss America I posted yesterday the white version was first with G-white and H-yellow. Would have been nice if they were consistent wouldn't it?! lol

Based on Ken's observations I'm happy to say the variant is 'Q' with a tentative rating.
It's all Bulova American Girl.
American Girl for sure, probably 'Q' but that would be tentative for me as well.
I think Q works based on the pricelist Ken found.
