·This Hamilton grade 992 was produced in the time-frame, 1929-30, when Hamilton began "Factory Casing" their movements. They also introduced a few new designs both case and dials. The Model #4 case was produced by Fahy's from 1927-29 in 10kt yellow and 14kt white or 14kt green gold-filled cases.
The #522 Montgomery dial was introduced 1929-30 with the block HAMILTON and they also dropped the fancy "scrolled-script" for an understated numeral font.
This green-gold filled 1931 example was the apex presentation of their iconic grade 992 in pure form as they will introduce the 992E the next year or so with its' Elinvar hairspring.
Hamilton would also stop production of the green gold cases within a year or so.
