1951 21 j 10bm model. The only crystal to fit is a CMY 312-6 for an Academy Award Model. The case is all 10k gold filled. The date, case, 21j movement and crystal all suggest it may be an academy, we know there are plain dial varients around. I can find no adverts for this model or hardly any other models the same as. So any ideas? Excellency or Academy are the two front runners at present!
In reply to Without an ad I will go by DarHin
Thanks DarHin and JP. I think I got it now. There are several crystals listed in these last couple comments. The catalogs say that most are listed for an AA YY only. Greg's crystal says AA. ...and all these crystals "fit" subject watch.
That's enough for me to change to an AA vote. Thanks for walking me through this one!
Shawn, how many watches have we confirmed as generic with just crystal specs?? In this case we have irrifutable proof comming from three different crystal catalogs that the only watch the crystal fits is the AA YY. I will agree with the lack of an advert showing the dial and hands limits the choice to a generic AA but that at the very least.
My final answer is generic AA based on the nice pile of catalog evidence.
