Hamilton pocket watch serial number dating
The Bulova and Hamilton stepped cases shown here on the left are a perfect example of this.
Men were preferring tank watches, however only round movements were available, therefore the case was stepped to accomodate the movement and make the watch APPEAR to be square. Even though watches were fairly small back then, the designs were bold and more masculine than before. A few words that sum up the 1950's are Futuristic, Automation, and expressive.
This will give a good idea of the manufacture date.
Hamilton made a variety of pocket watch movements after the turn of the last century.
Sizes ranged from ladies 0-sizes up through 18-size, Hamilton's largest movements.
18 size movements eventually gave way to slightly smaller 16 size movements and one of the lower priced 17 jewel 16 size movements is the 974.
The 974 went in to "open faced" pocket watches while the 975 went into "hunter cased" watches.
I am slowly adding serial number tables to this site. With the exception of BULOVA, the numbers on the inside and outside of the CASE ITSELF are ONLY for identification purposes - they mean nothing.
