GRAHAM traces its origins to London clockmaker George Graham (1673-1751) who is considered as the father of modern watch making. He is known as the father of the chronograph as he invented the start and stop device of the chronograph, the dead-beat and cylinder escapement, the mercury pendulum to compensate the influence of temperature on pendulums, to name a few. He also built the master clock for Greenwich Royal Observatory which timed most of the 18th century and lots of science instruments for astronomers and physicists. GRAHAM was revived in 1995 and is today a privately owned Swiss watch company. GRAHAM SA creates and manufactures its watches in La Chaux-de-Fonds, Switzerland.
