Does anyone know what year was the first year Bulova started putting antimagnetic on the dial? I have a Bulova on its way that has this above the six on the dial and Bulova in its normal spot under the 12. Thing is i dont know what movement it has as i never got a shot of the inside movement.

Check out the trademarks from some of Bulova's vintage watches.... very cool.  This might be cool to get into the database.

I just received a rose gold version of the "Patriot" that is identical to my yellow gold version except that the inside of the case back has no engravings whatsoever. It is an earlier version though with an 8AE double stamped with a delta over a circle. The outside has "14K GOLD BULOVA" and # 4535936 which is consistent with the yellow one. Also, the rose case back is a perfect fit on the yellow bezel with a good positive snap.

Is it normal for the mid 40's to have no markings inside the case?

Looking for 2 Bulova crowns i need one for a 51 Berkshire and one for a 34 President.
