Answer: AS 1674

 

Now I can file it away

 

Thats interesting... I was trying to do some googling too and found that Elgin is in Illinois (USA). So did they source a Swiss movement for their watches?

 

A little after WWII they began sourcing Swiss movements vs their in house variety.

 

Ah, cool! Good to know. I was looking at their in-house movements and couldnt find anything in that spec. And then notices the "Swiss"
