Antique GWR Railway Pocket Watch. I would assume late 19th early 20th Century. This watch measures 58mm in diameter or is 71mm from the top of the crown to the  bottom of the watch.  The watch weighs 154 grammes. The dial reads "GWR".  The dial is in good condition. There is a minor chip to the sub dial. The plastic crystal has yellowed. The case is in good condition. The caseback reads "GWR 2247".  The movement reads "Rotherham London 215495". The movement is crown wound and pin set. The watch winds, sets and works properly, keeping time.
