What is the correct description of each? saw one on ebay recently with the small red 24 hr numbers called Canadian - Which I thought was for use by US Military Railroads or Ordinance, etc and all black was for Canadian. Thanks, Jack Williams

Tough question, that's why no one has jumped on it, but I will give it a shot.

The majority of the Hamilton 992B's with the 24 hour dials that we assume to be "original", had the red 24 hour numbers.

It's very hard to say what's what after all this time and with all the swapping that has occurred over the years. All we can prove today is box sets and watch ads.

During WWII there were dial shortages and problems and we see things then that weren't usually seen. Hamilton shipped 992B's to Canada also in 1945 with 24 hour dials on them. We had the nations military and the nations RR's that had a real needed use for these watches during the War and supplies were short.

Do a search for "Hamilton 24 hour dials" (Find-Or-Search tab upper left on main page) and you will find enough research and study to last the night !
