Yep, we've been very lax about filling in this section. That's why I started filling in some.

Here's the 7 jewel version cal 703:

also this 7j cal 700:

Thank you for your additions here, that is great!

As always it brings up questions for me. Confused
In the material catalog it references cal 700 as 7j.
But there are easily found examples, one on ebay right now, of 15j cal 700.
Is this when they are transitioning from 15j 701 to 7j 700?
Does that make sense?
No worries if not sure, the Gruen mysteries abound...

I think they had a bunch already stamped "700" and were using them up.

Need to see the dial side on the movement, please.

Here is dial side, since no one has posted it.

/vgforum/index.php?t=getfile&id=7422&private=0

Bridge style between the 700 and 702 are different than the 703-705, but the keyless works are seemingly identical per the entry in the 1945 parts catalog
/vgforum/index.php?t=getfile&id=7421&private=0

Of note, Barnett's Green Book indicates that these were introduced in 1939. Online he says 1935. I'd say closer to 1931 for the 700. These are not listed in the 1929/30 movement catalog so that is a lower bound if taken literally. Models with this base caliber start to show up in adverts about 1931/32. I think my movement is 1933/34 as that is the time it was 1st advertised as the 'Master' (Thanks Bernd for the ID).

Hello, Jack! Great to hear from you! Good info, too.

I’m not sure which of the family came first. Most of my examples are 705. Wadsworth house 8mm nickel cases from 1930-32. They may have appeared as early as 1928 or 9. Here’s my earliest Gruen wadsworth 705 case: 5375963. It could still be later, as I believe the Gruen wadsworth numbers beyond 5.3mm stretched out longer than current theories. This one is marked unadjusted, while the earliest 8mm 705 nickels still have 2 adj.

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.
