London-British Museum-Breguet Chronometre1
1813 This chronometre never went to sea. It was used for expariments by Breguet, its maker, and then given to the Bishop of Cambrai in 1822. The dial shows the hours and minutes(left) and the seconds(top center). An inscription translates "The first piece in which the transmission from the train to the regulator occurs without friction. Made in 1813 by Breguet for Mr Belmas friend of the author No. 2741" Breguet and sons, Paris

London-British Museum-Carved Steel Hand20
Thomas Mudge 1765 By about 1750, precision regulators were relatively common. Here, the dial has 2 minute hands. The gilded hand shows true solar time -- the time indicated by the apparent passage of the sun in the sky, as shown by a sundial. The blued-steel hands show mean solar time, or clock time, which is constant. The disc in the arch shows the daily difference between the two, called the equation of time.

London-British Museu..Iron Clock Movement5
This iron clock is a rare survivor from the early 1500s. It probably started life as a small turret clock which drove a dial on the outside of a building. Later, it was converted for domestic use and the painted dial was added. Just beneath the bell is a swinging bar called the foliot, which controls the rate of the clock. Adjustable weights on the foliot are moved to achieve the best timekeeping. Unknown maker, north-west Europe Weight-driven, foliot, hour-striking (P&E 1967.0601.1)
