I'm thinking 1929 Envoy.
Case is marked "Bulova Quality" with a patent date of Jan 11, 1927. Movement is a 15J 10AN consistent with others in the database.
This is as I bought it but the hands and dial have both probably been relumed and the crystal is not original. It's nice, though.





For those that want to be precise:
The last ad of the Ambassador in the Saturday Evening Post (SEP) is in September 1929. The next month, a new Ambassador is advertised in the SEP. The old Ambassador model is re-batched as Envoy in an ad of the SEP in December. But with the new Ambassador coming into play in October, it can be assumed that the renaming of the old Ambassador to Envoy must have happened in October as well. Indeed a newspaper ad can be found of 25 October naming this model now the Envoy. The serial numbers for 1929 range from 900 until 953 (first 3 digits). If sales is taken in equal parts (12 months divided by 53), the 939 serial number ofthe subject watch places this model end of August, and therefore is still sold as an Ambassador.

.....wow, that's precise, but then why WOULDN'T we want to be so? A bit of a stretch I'd say on the serial number being August but in truth either ID could be considered appropriate. It could also be argued in favor of Ambassador only in that Bulova made more of the Ambassador models in 1929 than the Envoy. I'll go with you Alex - Ambassador

HI, guys.
A couple question:
1. Is there a reference I can go to for more info like this. It sounds like there's some good nuggets to be gleaned.
2. I have a 1928 "Envoy" in the database. Sounds like it should be an Ambassador.
Thanks.
