Royal Navy pocket watch made by W Ehrhardt 1913

Here we have a WW1 British Royal Navy silver deck watch by W. Ehrhardt, London. The watch number is 609809. The complete watch is in fair condition and unrestored, this has a very long and widley travelled history, and this will be held at the National Maritime Museum for further information. 
 

The face has some damage to the one and 2 o'clock digits, This does not detract from the overall fair condition and is hard to see with the case shut, the cases is sterling silver and dated 1913, with the watch retaining its movement and the broad arrow mark the timepiece. The watch keeps good time and runs well, but will need a service.
