Not sure what came first either. I think the 700 series was a response to the deepening depression to make an inexpensive watch... flat HS and 7 jewels, going up. What I have noted on timing is that some have 'Guild' some have 'Gruen Guild' and some (seemingly more recently) drop the 'Guild' marking. Some are marked with the hairspring material 'Conoruma' which I think you guys sussed out has a start date, and some are not marked.
All I know is based on hard work & writing by others. I can only aspire to augment this body of knowledge. If I am wrong it is because of my own failings. -me
