Hi John, I just noticed this post. Not sure if anyone will see this, but here are my observations about your watch. I agree that it probably dates to 1955. The serial number would help to establish an approximate date. That should be stamped into the back of your case, but unfortunately your case has been quite heavy polished, with a fairly rough grit like steel wool, which not only diminishes the value but appears to have taken off the serial number, at least judging from your photo. The front of the case also looks like it has been polished. The hands are not original to this watch. If you go to polerouter.com you will find many examples of original hands. The minute hand is not supposed to go beyond the inner edge of the chapter ring, and yours goes almost all the way to the outer edge. Also, the tail of your second hand has been broken off. The crown, as others have noted, is not original, and I am of a different opinion than citizenrich who thinks that it will be easy to replace. Some early Polarouters had unsigned crowns, but those are of a very particular shape which are not easy to find. Many Polarouters and as far as I know all Polerouters had signed crowns, of several different designs, and they are extremely rare. The good news is that your dial appears to be original, and the movement looks to be in very good condition. It is a beautiful watch and you should enjoy wearing it. It is, however, on the lower end of the scale in terms of value due to all of the issues I have noted above. If you want to collect Polerouters, perhaps you can use this one as your daily wearer and look around for another one in more original condition so keep as a "queen" (a watch that never gets worn).
