I read somewhere that the BXW we see on Swiss movements is an US import code spicific for Bulova required on "finished" movements coming into USA. It was not required on Swiss eubauchs coming to USA. Other watch manufacturers had their own codes assigned to them. I just don't remember when this requirement started.
Can anyone refresh my memory....or correct it please?
Thanks Mark
I found this thread:

and others, but none which indicate when this may have started.
Here are allot of import codes for watches.

Still looking for a date range for this requirement. Also thinking.... someone said a case SN w/ first charactor being a letter rather than number may have been used on watches intended for other than USA markets.
So a swiss movement made during the timeframe of the BXW requirement but lacking such a hallmark may be likely to be in a case w/ first SN letter?
