Here's one that's going into the vault, as many of you know the Quadrons are one of my favorites! I acquired it in 2010, and am just know getting around to cataloging it. It's nice to get a Gruen once in a while that you can "positively ID" from the factory's 1929-'31 Guild Book! Love the "W" after the "8." First time I've seen a number/letter combination for the case style!
Model name : Quadron 63
Type : Quadron, 15J Guild movement
Period/date : late 1920s
Gender : Men
Case Maker : Wadsworth
Case Material : 14kt gold filled
Case Serial : 5,419,980
Case Style no : 157/8W
Caliber : 157
Movement Maker : Marc Favre
Movement Serial: 1,166,816
Bracelet : Leather band
Other info (my opinion only): Positively ID'd on Page 16 (top center) of my Gruen Book, and also page 79 of the Gruen Guild book (picture included below). Nice case design on this, gravitating more toward the "streamlned" designs of the later Quadrons versus the "Art Deco" designs of the earlier ones. The slits carved into the tops of the lugs are a nice touch, as is the "crown guard" design of the case. The domed crystal is no doubt a replacement, and not correct for this model. If anyone can help me obtain the correct glass crystal for this, I'd be much obliged!
Enjoy!

I had some discussion with Dr. Ranfft on the 157 and his basis for the Alpina link is the occurrence of Alpina marked movements. In doing searches for patents I found the Favre patent online last year and I think there is no mistaking what the movement is: LINK

Good news. There are more! 
-pocket watch 750 W, 14k gold filled, wadsworth (1x)
-wristlet 127 W, ultra quality gold filled, wadsworth (1x)
-wristlet 819 1/2 W, ultra quality gold filled, wadsworth (1x)
-wristlet 819 1/2 G, ultra quality gold filled, wadsworth (2x)
-wristlet 825 G, ultra quality gold filled, wadsworth (1x)
-wristlet 24 Y, 0.935, ? (1x)[/list]
-wristlet 8 3/4 ligne W , ultra quality gold filled, wadsworth (1x)
-wristlet 10 1/2 ligne W , ultra quality gold filled, wadsworth (1x)
-wristlet 10 1/2 ligne G, ultra quality gold filled, wadsworth (1x)
-convertible 10 1/2 ligne G, ultra quality gold filled, wadsworth (2x)
-quadron 157 8w, 14k gold filled reinforced with extra gold, wadsworth (10x) -> for example Quadron 15
And diamond wrist watches in the guild book have some special lettering. These "Design numbers" are also inside the case:
Cartouche 105 1w, iridium platinum (1x) -> Design 1W105 (page 109, 1929 Guild book)
Cartouche D107, iridium platinum (1x) -> Design D1077
Quote:I think the W means wide.
In the 1929 Guild book Crystal chart you see style 1: 157/8w 117/8w and style 6: 157/8 117/8. If these crystals are the original size, you can see that the 8W crystal is bigger overall. So yes, it could mean "wide". But I have some doubts seeing those "G"s and other letter markings.

Quote:What are the style numbers associated with these watches?
Ahh, well, depending on what you call a style "number". I shared all the info on these watches, including what might be the style number OR could be the movement caliber number.
I think that not all the Gruen watch cases show the caliber number (for example my baguette only has a style number inside the case back).
So style numbers could be: W, G, 1W, 1/2 W (don't know movement 819 1/2), D, 24Y, etc...

I do keep my personal watch collection in a safe deposit box. 160-plus watches are just too many to keep in the house. But I visit my "babies" regularly and rotate through the collection and bring them out into the light and wear them on my wrist. At the moment, I'm wearing a '50s vintage Omega Seamaster automatic with date at 6:00.
It was on ebay last week. In fact it was Plate 24B, the paris square in silver (Guild book 1918, page 40)
