992 Case screws

Hi,
Do the case screws for the early model 1 992's have smaller diameter heads than the newer 992's have?
Thanks,

How about a picture? I'm not sure what you mean by "smaller."

Donnie,

Case screws were slightly smaller on the earlier Hamilton 16-size watches than those used later, but I agree with Ed that we could not guarantee authenticity of components without seeing the watch in question.

Ed,
I bought this watch in a swing out case which had the flat head type screws seen in the picture below. I was going to put it in a different case and was going to use some case screws from another newer 992 but the screw heads will not go down into the recesses of the movement and will not allow the case screws to tighten down against the case, thus the movement is loose in the case.

It looks to me if the case screw heads were smaller they would go deeper into the movement, allowing the movement to tighten to the case.

Thanks,
Donnie T.

I suspected the earlier screws heads were a fraction smaller when the newer ones would no go all the way down.

Thanks,

Yes Donnie, here is proof the case screws are ever so slightly smaller on the earlier Hamilton 16-size watches, see the example of a Grade 990 below this posting which is also in a Swing-Out Case. Observe carefully how the case screws fit very precisely, look closely, nothing like seeing the evidence clear and close-up! Lindell

This early model number 374629 is entirely correct...
