Hamilton Railway Special (Railroad Grade) Pocket Watch 992B movement, 16 size, 21 jewels, Adjusted Temp. And 6 Positions, lever set.
992B movement is not compatible with 992 movement. Its parts are not interchangeable.
The pocket watch sustains accurate time.
Got my 992b about a month ago. After adjusting the regulator a little bit to compensate for my daily routine, the thing runs +/- 3 seconds per day, and usually ends up only about 10 seconds slow by the end of the week.

I'd say that's pretty accurate... As far as I remember a railroad grade movement had to stay accurate within 30 seconds of a week. So 10 second variance is very accurate.
Congratulations on your acquisition.
