Hamilton 992

The 992 was Hamilton's first main 16 size, 21j railroad pocket watch. It was made from 1903 to 1921, in quite a few different variants. The very earliest ones were single roller with a fairly elaborate damaskeen pattern, composition jewel settings, and a brass center wheel. Later versions switched to double roller, a gold center wheel, gold jewel settings, and a simpler narrow stripe damaskeen pattern. There were also some "special" patterns, including two-tones and others.
One will sometimes also see "992P" and "992L". The P and L refer to pendant and lever setting, respectively-lever setting is by far and away the most common.
The 992E was a 992 fitted with a blue Elinvar(elastically invariable) hairspring and solid monometallic balance. The earliest of these had the same narrow-stripe damaskeen as the later 992, but most commonly seen is a wide-stripe damaskeen pattern. The pallet bridge has the word "Elinvar" stamped into it.
The 992B was a complete redesign with few if any parts interchangeable with earlier models. The key feature is the white Elinvar extra hairspring, although the plate layout and most of the other key visual features are different. The damaskeen is a narrow stripe, although all the plate lettering is filled in with black rather than gold as on earlier watches. The serial number generally starts with "C", although "4C" and "S" are also sometimes seen. As far as I know, all 992Bs will say "992B" on the movement. They are also often(although not always) fitted with dials that say "Hamilton Raliway Special."
There's a lot to learn about all three of these watches, and this answer is only intended to be an overview to help you spot and differentiate them. There's a lot of great information about all three contained in old threads. If you look at the "Hamilton threads" sticky at the top of the page, you can find some of these easily.

One correction and a couple of comments: The 992 was actually made from 1903 to 1931.
In the "Halligan Files", the 992 is listed as having three models, i.e. first model (lever set) as Ben mentioned was introduced in 1903. The pendant set 992 wasn't introduced until 1912.
The second model was introduced to the trade, Feb. 1, 1915. The gold center wheel, gold meantime screws, and new damaskeening pattern was added to this model.
The 992 was first announced as being available "factory cased" on Oct. 29, 1924 in the "First Model" case.
The third model (Elinvar) was introduced in Aug. 13, 1931.
The new model 992B was introduced in Nov. 1940.

Sorry, that's what I get for not proofreading. I looked up the dates in the NAWCC database(since I couldn't remember exactly), and for whatever reason transcribed 1931 as 1921.
I appreciate the correction.
Ok from a collector prospective which is more sought after I know some more valueable then others I know we cant talk price but what makes some more valueable then other Ex. A 992 21j gold center wheel,GJS,
5P,SR & DR,NI,OF is less valueable then and 992B 21j,LS, Adj 6P OF seems the other way around just wondering how all that was determined

Just between us, I predict that the first model SR Ben mentions is a sleeper and will eclipse the popular E model.

here is a picture of one of my 992B's ... 1952 ... the 992 you have was the forerunner of the B model
and great watches for sure.

the 992B's tend to cost more when you purchase them ... they were the last of the great Hamilton watches and deadly accurate timekeepers .. If you can nail a 992B reasonable go for it .. they are very sought after

Yeah Ben, that's what I'm talking about. I've got a nice trade when you're ready.Something like this?
(the only 992 I currently own)
