LNWR Guards watch By John Walker of London. A brass cased fusee Guards Watch dating from circa 1840, this important timepiece was used by Guards, set and locked at Euston, then travelled with the Guard so he could confirm the time at the Stations at which they stopped. Certainly in use before Greenwich time signals were sent by Telegraph. The Brass case is engraved to the front John Walker 48 Princess Street, Leicester Square, London and to the rear London & North Western Railway No 144 1038. The English Lever fusee movement is in working condition. This is one of the rarest and most important railway watches to come onto the market in recent years.
