I picked up this Hamilton watch company recently and cannot find out much about it. I seems to be from the 60s, has .00002 resolution and .5 travel on the lower anvil. Any information would be appreciated. Thanks

I have a similar "head", same resolution, but marked 2-0-2 1 Div = .000002".
My one is a basic DI, without the "works" your one its atop.

Also it's sibling in ten millionths per division.
These are the legendary "high amplification" Hamilton mechanical movements - among the finest of their type ever built, any continent, any era.
Dorsey Gage had published the history on the web at one time as to how they bought the production tooling AND hired the Hamilton staff who had built these when they took it over. Dorsey then sold them under the Dorsey name, and also furnished them to Pratt & Whitney with P&W's name on the dial.
I have some of each - Dorsey & PW dial branding. Only my two large 4 AGD size have Hamilton's name, packaging, & P/N.
Dorsey then went through some business organizational changes. The unit that still made the former-Hamilton goods became "Dorsey Metrology".
The Hamilton-derived line in the large 4 AGD size and fine resolution - 10 and 20 millionths - were shown on their website for quite some time.
I didn't find them on a recent website browse though.
Dorsey should still be able to service this unit, even if they no longer make new ones.
They are a tad touchy, but very lovely ....when you actually NEED them!
