Pocket watches, we have all seen them, especially if you are a fan of old English movies or Sherlock Holmes films you would have seen one. A watch made out of some type of precious metal, silver or gold or even in some cases steel with a cover to protect the screen and a chain attached to it instead of a strap which was attached to the pocket or belt or even placed in ones pocket.

When you are in the market for the best vintage railroad pocket watch available, something noteworthy is that they have only every been manufactured in the USA, and have had particular standards that had to be met. The size of the movement also needs to be paid particular attention to. The size of the watch's movement is determined by measuring the dial across the centre and then through to the point where it is the narrowest. The standards set by the railways meant that the watch was required to meet size 18 or 15.227 mm precisely. A larger size of 16 or 16.919 mm came into force in the 30's.
