The Chinese Duplex movement was invented by Charles Edward Jacot in 1830, a movement of the second’s hand, from one second mark to the next, which meant one tooth of the escape wheel passing per second. This was done to give sweep-seconds. The duplex escapement has a slot in the roller on the lower part of the balance staff on the right, that allows a pointed tooth of the escape wheel to rotate to the next position, where it is held up. This causes an upright tooth on the escape wheel to impulse the balance staff. Duplex Escapements History: The duplex escapement has a slot in the roller on the lower part of the balance staff on the right, that allows a pointed tooth of the escape wheel to rotate to the next position, where it is held up. This causes an upright tooth on the escape wheel to impulse the balance staff. The duplex escapement originated in France circa 1724, and was invented by J.B. Dutertre. The duplex escapements were popular as well among the English makers of good watches from the late 18th to about the mid 19th century, until supplanted by the Detent and Lever escapements. Pierre Leroy is said to have invented it c1750 and in 1782 a patent was granted in London to Thomas Tyrer. It continued to be used in some machine-made American pocket watches. The escape wheel has two sets of teeth at right angle, on for locking and for impulse which is given in one direction only to an impulse pallet on the balance staff. Some continental versions have rest escapement. Unsigned – Swiss made - Circa 1850 – Diameter: 54mm – Weight: 110.7g WE SHIP WORLDWIDE This is a true collector’s item!!
