Old timepieces evolution
Almost all watches of the late 18th century were made without cases. Double and triple cases remained popular only in England. But even there watches with several lids began to appear in the late 1820s, e.g. works by the English firm “Dol-ter”.
At the beginning of the 20th century Swiss watchmakers went over to semi-automatic production. They produced up to 100 thousand items a year and sold them all over the world. Watches became mass produced items.
In the course of the 19th century watches were technically improved. Pocket watches no longer employed keys for setting the mechanism but heads. It was invented by Englishman T. Prestu in 1820, and the Swiss A. Philipps began to use this head not only to set a watch running but also to set the time. The third, second, hand became usual in the watches of the second half of the 19th century.
Despite mass production, the best samples of watchmaking combined high technical qualities with exquisiteness and refined decoration.
