Bulova 1939 Ambassador W/ 21 10AE...WHAT DOES THE TRIPLE A STAND FOR???

I have the same AAA marking on my 1940 Ambassador 10AE movement. The AAA marking is not on my 1939 Ambassador with same movement. 

I believe the subject has come up & had been discussed here before. The concensus was that it was an attempt to show off a top quality Bulova movement. However, some marketing genius realized that no one would see it except a watchmaker or some watch owner with tinkeritus. Not having turtle recall, this is not exactly but, that is what I recall.

I'm pretty sure your right Wayne, I seem to recall the original speculation was related to the Academy Award series but the AAA marking showed up long before Bulovas agreement with the Academy.

I think that triple A at the time is like a 5 star hotel rating, First Class Finest Kind sort of thing.

the 'ACADEMY AWARD' discussion was related to Bulovas' use of the 21 Jewel 7 AA designated movement in relationship to the 7 AK movements found in the 'EXCELENCY' line.

AAA stamped on a movement has been seen in additon to the movements model stamp.

eg: 10 AE  AAA

AAA could mean a miriad of things - All American Assembly for example.

1940 10AE 21j ADJUSTED                               1937 10AE 21j ADJUSTED Arrow-1939 Shield

I would think that a watchmaker would make all adustments required for the movement.

 I just got my packages for the day... one of them has a 21 Jewels 7AP movement with shield date code. It also displays the mark "AAA" as seen below.

In that era "AAA" just meant quality. I cant say for sure thats what it means here, but probably so.

All of the AAA marked movements encountered so far are 21 jewels. Which supports the first class, finest kind, quality, short-lived marketing magic. Latest movement with the AAA stamp so far is dated 1940. If anyone spots a AAA stamped movement dated after 1940 please copy & post. 

None are Swiss, if anyone finds a movementt stamped SWISS & AAA please do the same.
