Peter S. BalkanEarly Hamilton Signed 16sz Case Question
Funny thing....
I was looking at some cases recently and found a Hamilton signed, 16size shown below.
Does anyone know how and when these cases were used by Hamilton? I wonder why Shugart doesn't include them in the book.

Tom HuberPeter, I know the 956 was factory cased in a variety of Hamilton hallmarked cases like yours.

Terry HillPeter....
These are not an easy find... in good condition...

Mike CamelinPeter, yours is from about 1919 from boxed sets I have seen.
These cases were indeed used in the teens as you are hearing on many of the Hamilton models, some were triple hinge and some even made in 14 K Solid Gold.
Hope this helps and Happy Hunting!

Jim HaniePeter,
Hamilton made about 4 early factory cases. The one you are showing is the type I believe were used on the 956. Most all correct 956's that I have seen including boxed examples come in this case.
The 994 were factory cased in the 14K and non gold cases.

Terry HillPeter,
is your example a 'clam shell'...?
(you open the front cover, the the movement swings to the side?)
March 27, 2006, 10:12
Peter S. BalkanTerry....
Yes, that's exactly how my case opens, it's quite possible that the bow was changed.
March 27, 2006, 10:42
Terry HillThe Clam Shell case seemed to be offered with the 956 movement...and not often the higher grades
The Swing Ring and the Triple hinge were offered with the higher grade movements according to the catalog page....
Also, the April 1997 article in THE BULLETIN gives some additional info on these cases...

Lindell V. Riddle
Hope this information is of help to those who might be unfamiliar with these interesting cases.
When opening this case, the bezel rocks forward, being hinged at the 6:00 position. For movement access you then carefully insert your thumbnail or sharp case-knife on the edge of the movement ring in a cut-out located by the 3:00 position. The ring which holds the movement swings to the left being hinged at the 9:00 position.
Below Hamilton factory case number 10618872 with "Hamilton Watch Co., Lancaster, Pa." along with the Hamilton crest and "Guaranteed 25 Years" markings.
Here is one opened up to show how these work...March 27, 2006, 14:07
Mike CamelinThe clamshells were used mainly on the lesser grades and not usually the high grades, but they are still neat cases and being they are old cases, finding any of them in good or better condition is a hard thing to do.
Also, Lindell, yours probably dates to 1919 as well, although I do have a couple very close in serial number to yours that are late 1919 or early 1920 and one, only a few thousand numbers different from your case is engraved 10/7/20 which is probably/obviously when it was sold by the jeweler. The clams are neat in design and I wish more were still with us and not worn away. Happy "early Hamilton case" Hunting!

Terry HillLet's try it now...... ok working...
This is a scan from Ehrhardt's book, attributed to 1913... of course it is showing only a triple hinge....

Terry HillTom,
Often times, yellow and green or white will have 'different' serial number sequences...
don't know why though....

Charles R. SidesHam clam shell # 10124230 on 996 #1182865
Engine turning is worn, but no brass.
I have another, but can't find it. Better condition, but has a guys name in the inside back lid.

Ethan LipsigHere is a 1911 Hamilton 950 (SS # 785,630) with a 14k solid gold Hamilton factory triple hinged case # 6415033.
March 28, 2006, 02:27
Mike CamelinEthan, It appears your watch is original. Or I should say movement original to the case, movement dating to a finishing date of 1911 by the Gelson list and the case is a dead on match by serial number of the same year when compared to boxed sets I have seen.

I will make an attempt to dig out the top hinge examples I have.. to me, the style and appearance is contemporary with the other examples...
