Pictured are two Hamilton watches--a 992-B (left) and a 950-B (right). Now they both have differences of: case models, dials, hands and, obviously, the movements inside. So what could these two very popular Hamilton railroad watches share in common?

The answer a bit later. Care to guess now what it is?

Well Lin, that didn't take very long. You must have had some "INSIDE" (pun intended) information. The two movements have identical serial numbers (8003) aside from their necessary "C" and "S" prefixes. What are the odds of accomplishing this, I wonder? Anyway, here are the movements!

Really cool Larry.

I had wondered if anyone had tried to put together a 992 and a 992b with the same numbers, but never considered doing so with 950b & 992b.

A nice pair for sure

Charles & Lindell, It just happened when I found the 950-B and remembered I had owned that number in a 992-B for a long time. Not something that I set out to do at all. I guess if you tried to do this, it would never happen.

Kind of interesting that the 950 being later has no gold center wheel or jewel settings and the 992 does.

I know it is bue to the 950 being newer I just thought it was interesting.

Nice pair.

Aaron and others,

Your knowledge is correct as the 950-B (S-8003) is of 1950 production, while the 992-B (C-8003) was manufactured early in 1941, according to the most-reliable Gelson list.

There were many changes implemented in those nine or so years at Hamilton. Examining a 1950 example of a 992-B movement would reveal the same cost-savings applied to its components, I'm sure.

Best regards,
Larry
