This is a Bulova 10KT white gold RGP diamond watch with a date code on the case of 1963. The bezel has a diamond on each side and a beaded lug. On an interesting Speidel gold filed bracelet with inset diamonds or glass. The movement is a 5AR with a date mark of M2. I found the following ad for this gold color case which is a great match as a La Petite. Mine is a white gold version.
I would agree this is a La Petite. Here is another ad showing the white and yellow, but no variant ids. The 1964 pricelist shows several variants of this model at the $59.95 price range (A, AA, AAA, B, BB). I'm unable to narrow down a variant, but La Petite is the model.

Hey Ken, good ad find. It appears to call out La Petites by sub-names -
La Petite,
LaPetite Square,
La Petite Swirl,
and La Petite Marquise.
Each listed as yellow or white.
I wonder if this was part of the official designation, with perhaps the first with no sub-name "La Petite" being A (yellow), AA (white) and AAA (Rose Gold), La Petite Square being B and BB, etc.
I'm not saying we should try to give a letter variant without conclusive proof; I'm just thinking out loud, so to speak.
Should subject watch be assigned "La Petite Marquise" no letter variant? That gets my vote.

I don't think those additional advert descriptions were part of any official name, at least there is no mention of them in price lists. Seems more like a marketing attempt to give them some distinction.
BTW - here is the 'A' variant:
Pricelists sometimes provide us case color, but none shown in 64's list.
