Wow, a nice example! The engraving details are very crisp!
Here's my shot at dating it with case #s. The case was likely made mid/late 1925 and I believe is actually an unsigned Wadsworth case. Many of the Ultra Quality line, including these and the tanks, remained unsigned long after gf/reinforced cases started being signed, but they follow wads case #s, including the jump to 5mm in late 1925/early 1926. This case was made either just prior to that jump or maybe even concurrent: it appears Gruen built up a large stock of GF Quadrons right at the 5mm jump, occupying much of 5-5.1mm.
I believe the movement may be later, perhaps 1927. Can't tell for sure, but from the font your sn looks like it could be 151k vs 161k. The 179 examples I have for this time indicate mvmt #s 118k @ UQ case # 995k, 129k @ 1028k, 138k @ 5108k, 148k @ 5110k. Mid-1928, 179 was @ 173k.
Looking forward to hearing what others have to say.
My two caveats:
1) I'm wrong many times a day --just ask my wife!
2) Always seeking to learn more
