Default The Hamilton 950

I was helping a friend get some information together on the Hamilton 950. I put together a small chart of them and after looking at it I realized that we need some more information on them to answer some questions about the pendant set and lever set models.

In addition, the bridge plate at the top holding the crown & ratchet wheels was chaged after the first 8 runs . It was split making the watch a 6 bridge model instead of the original 5 bridge model. Can't you see it now! ( NEWS FLASH EBAY= Rare 5 bridge Hamilton 950 ).

Does anyone have a 6 bridge model before 856,000?

There is a service screw by the crown wheel in the pendant version to lock out the clutch for servicing. This keeps the hands from being set. I am speculating that many watchmakers simply left this screw and lever out in cleaning as it really didn't serve any purpose other than holding up the clutch gear. Some collectors have speculated that these watches were converted to lever set by the factory , so we need some examples to see if this is true or false.

I will try to add these numbers as they come in to the list with Sam's help.

Thanks in advance.

Jim,
This doesn't necessarlily apply to the 950s:
I have seen this hole/screw on most pendant set 16s Hamiltons, most commonly on the 974s and 992 (yes pendant sets). I had assumed, like probably most of us, that the screw was removed after it left the factory, as it has no real purpose.
I have never seen the hole/screw on a lever set version that I can recall. If I did, I would probably assume that the lever set was an after market conversion.

Talking

Wes,
Yes, this thread and discussion is on the 950. I, and most Hamilton collectors are aware of the service screw on the 3/4 plate models and it serves the same function that I have described above. I was not describing this as a oddity but as the spot to look for when checking your examples.

Hopefully , if we can get enough examples on the 950 we can see if the lever sets had this screw hole by the crown wheel, which would indicate that Hamilton either converted PS to LS or used the predrilled plate for a PS on the LS.

Also, to be clear we are trying to find out the cut off serial number for the 6th bridge.

Jim,
I misunderstood the point of the thread - my bad.

I thought there was some insinuation that this hole/screw had been spotted on the lever set Hamilton, which wouldn't make sense unless it was not factory.
