and some more Hamilton information:

The 999B list is as follows:

2B001-2B700 Nov.1943 to March 1944

1B001-1B450 May 1943 to May 1944

1B4001-1B8208 Dec 31,1948

1B23,500 1953

1B27,500 1954

1B27,501 and higher, till end of production in the mid '60's.

 

In addition here is some info on the 992B family of watches...

All 992B had a serial number starting with C

All 2974B had a serial number starting with K, or 2K, total production in excess of 16,095...

2974B production was from 1941 to ??? 2974B production at the end of WWII was 15,563

All 3992B had a serial number starting with 3C, total production of 2497 or maybe a little more...

3992B production was from 1943 to1945

All 4992B had a serial number starting with 4C, total production of 142,000 and higher..

4992B production was from 1942 to 1966?. 4992B production at the end of WWII was about 95,000 more were made during the cold war,and even 'Nam.

The myth about the "Officer's Model" 4992B in the Coin Silver Case, is just that, a Myth. in April 1943 the spec's were changed to allow the use of a "non-critical" alloy, in order to conserve Nickel, the major component of "Base Metal". Remember the Steel Pennys made in 1943? same deal, trying to save copper there... All 4992Bs in silver cases should have serial numbers from "43 ... and over 11,000 were made...
