Just checking the movement is 1926. I have a 10AA with similar serial number which is dated 1924.

My 10AA is 16 jewel, the ad says 15 jewel.

What is the jewel count on your 10AA?

What s the serial number?

16 J certainly dates it around 1924/25

My 1924 10AA is 17J with serial number #124019

I finally realize I should have dated this watch to 1925 to coinicide to the movement circle symbol. Changing the date would also change the name of the watch a 1925 Diplomat. Do you agree?

If it has the circle movement, then yes 1925 would be the go, but like any Bulova watch its hard to know when the actual watch was released to the public.

Lets say the movement was manufactured in late 1925 in Switzerland, then cased and sold in1926 as the Ambassador.

Or, it was manufactured in early 1925, cased and sold in that same year.......Diplomat.

This could apply for any watch I guess...it certainly applies to the original Lone Eagle series (we know this becasue we have a timeframe to work by for the release of this watch).

I gather the dial and hands are not original to this particular watch.

I note that your serial number is earlier than the 10AA I have. Mine definitely has a * for 1924, so as usual that makes no sense what so ever :-)

Any chance of a better photo of the movement?

I'd love to be able to hit those 3 stars to confirm it as a Diplomat, but need to find something to positively seperate it from that of an Ambassador.

The 16 Jewels may be the key.

I have enough confidence in the data to call it a 1925 Diplomat. I'm sure that the dial is original & the 10AA 16j is probably the only difference with the ads. The only square dial watches with no seconds chapter are the 1925 Diplomat and 1926 Ambassador.

Based on the Serial number entered the Case dates to 1929* - in 1925 the Case would be 'Tri-fold'.

* Hands would be correct for the era.

Houses a 16j 10AA dated by circle (1925) and has a movement SN.  Movement swap w/ earlier movement?  Here's the 1929 ad Envoy Fifth links above; note sub seconds in ad but not subject watch:

Yes, earlier Movement (and Dial) in a later Case.
