George Graham, an eminent member of the Royal Society, devoted his entire working life to the art of measuring time and to the development of astronomic instruments

which also helped Edmond Halley to produce his famous sidereal maps. Amongst his many inventions, we owe him the one for which he will always be remembered - the chronograph.

One of Graham's latest creations is a new edition of the famous “chronofighter”, originally made for RAF bomber pilots during the second world war.
