Hi All, I have not posted here in a long time, but figured this was worth sharing and I have a couple of questions. I was at an estate auction today and in among a box of pocket watches I found a beauty! Been a while since I got this lucky! Waltham, serial # 7711674, model 1883, Grade Crescent Street. What makes this one more interesting is that it is Marked "Canadian Railway Time Service". I have done some research, but cannot determine how many of these were made with this marking. Does anyone know? I have a number of model 1883s, but this is the first one I have encountered personally marked like this. It has the correct Canadian 24 hr dial (which will clean up beautifully) and appears to be in its original case (Manufactured by BANNER). I realize that Waltham manufactured the watches and exported the movements to Canada to be cased. The case is very worn.....not sure if I should try and shine it up or not....what is everyone's opinion on that?
