Hamilton 992B Railway Special Appropriate Case?

[pyrettablaze]

I Have this 992B Hamilton Railway Special and The production dates that I have seen for this serial number C247276 State that it was made between 1940 and 1954. Is there any way to get a more specific date or is it all just appoximate? Also I was trying to find out about the case, if it is original to the movement. on a chart that I found on there it shows a picture of a model #2 case which seems to look like mine. Would this be the correct case for this watch?

Your watch was made in 1948 and the no 2 case is quite appropriate.

Use the search function as there are several threads on 992B cases.

Thank you, Very Helpful! I looked at the case charts and thats how I found the number 2 case, Just wanted a 2nd opinion. Thanks!

pyrettablaze,

Without having the original box/label that shows the movement/case serial numbers, it would be very difficult to know with absolute certainty, if your case is original to the movement.

From the photo, it appears you have a Melamine No. 168 dial.

Agree on all points so far....

Model 2 case...

note the lack of patent date and the serial number...

this is from the correct time frame, after the H prefix and before the J prefix cases.

it also appears to be a 168 dial, appropriate for the time frame.

As Terry states above, their were different numerical grades on the 992's.

Actually I split the Hamilton database into Grades 992, 992B, 992E,992L, and 992P.

The alphanumeric grades give my sorting program fits, and I have yet to resolve it satisfactory to list the runs out separately.

Thus thats why the 992B's are "lumped together" for viewing purposes.(i.e 1940-1954).

Obviously we have the Hamilton guys that can readily provide information, so it is not a high on my list of things to resolve at this time.

The prefixes Henry speaks of are the movement serial number prefixes... C for 992B, S for 950b, 4c for 4992b (and 992B), 1B for ball 999b, 2b for 992b and 950b.

Hamilton used movement prefixes on other grades also, mostly with Post WWII production.

I had the same issue with database in works or excel... :bang:

The prefix I speak of above are case prefixes... ;)

... 1B for ball 999b, 2b for 992b and 950b .... )

Oops, that would be 2B for Ball 999B and Hamilton 950B - wouldn't it?

[terry hall]

yes.... :% thanks for the correction... i flubbed that one. reckon if i owned one i would have remembered better...

'lawd I apologize and remember all the .... ' :clap:

Presumably we know what order the prefixes occur, so it should be possible in a database to just substitute a numeric value that will preserve the sort oder in place of the prefix characters.

When displaying the results of the sort, you would resubstitute the prefixes.

The easiest way to do this is to create another field called something like "SortOrder." For all watches without prefixes, the number would be the serial number.

Terry- I apologize for muddying the water, when you were explaining case numbers, and I barged in with movement serial numbers.:o

Tom- certainly I will ponder your advice, and thank you very much.

Problem is with Hamilton Movement numbers, if the Hamilton wristies are counted there are almost 10 million Hamilton movements to account for, and only about 4 million of them are a regular serial number, so it gets kinda confusing. :bang:

[Don Dahlberg]

The number 2 case was introduced long before the 992B existed and ran until about 1954. So 1954 is the latest date for your watch. If you have a Melamine dial, then that dates it post 1947. So the best we can do is late 40s to early 50s.

The list created by Lowell Halligan, Hamilton employee in charge of keeping sales history dates your serial number about 1948.

So everything is consistent.

Thanks Don.... and research also proves it out :thumb:
