I have this 992B in a Star case, after checking thru the Hamilton data, I see that in some of the later ones they did use the Star cases, could this be one of them ? I could not see any other case screw marks on the case. Ser# C412891 case# 8306841.
Thanks,
Bill

Movement: C412891

Thanks Lindell,
Here are some pictures of the bezel and back of the case. The dial has several h/l's but at this time I am not to worried about it, it will make an OK carry for me, as it has been keeping +/- 1 sec a day.

[** NOTE** I started working on this before Lindell and Bill posted and much of my information has already been told by Lindell at this point, but I will leave it here to add a small part to Lindell's informative post.]

I don't know what case is shown there besides it being a Star watch case. Around 1955 Keystone was absorbed by and into the Star Watch Case Co.

The Star Watch Case Co. made cases for the 992B in the models 15, 16, and 17 and their serial numbers started with "R" and later still their serial numbers started with "P". Earlier Star made the model 12 case which was in the late 40's and the model 12 case was short lived and only used one year.

The watch movement pictured is from ca. 1954. The Star Watch Case Co. began using the pictured registered "trademark" logo on the case in this thread in Feb. 1925.

Your question is ;

I see that in some of the later ones they did use the star cases, could this be one of them ?

Since your movement comes from 1954, I don't believe this particular case was used on the 992B you have pictured.
