Description: Capped, gilt brass, full plate cylinder fusee movement (40mm diameter), cock with un-pierced foot and table with symmetrical engraving centred with a diamond endstone, movement number scratched inside the cap, a typical Graham workshop custom. Cylinder (dead-beat) escapement retaining original Graham banking, brass escape with 13 teeth. Steel balance, 3-turn blued-steel balance-spring. Back plate engraved ‘Grahams Succ.(esso)r London 6648’. Cap engraved ‘Graham’s Succ.(esso)r Tho.(mas) Colley LONDON’. The movement later ‘enlarged’ with wider brass-edge and custom made white enamel dial. (A)
Additional Info:
The last recorded piece signed by George Graham is No. 6590, so this movement is one of the first pieces made after his death. Later movements will be signed as ‘Grahams Successors’. This is one of only about 10 known movements signed by either Colley on his own, or with his partner Samuel Barkley or later John Priest. (A)
