Historical context
Precision & Scientific Horology (1750 – 1850)
Harrison solves longitude; Mudge invents the lever; Breguet's Paris workshop defines the modern watch.
From 1750 to 1850 the watch became a precision instrument. Mudge's lever escapement, the cylinder escapement, Lépine's thin bar calibre, Breguet's innovations (overcoil, tourbillon, perpétuelle) and the pocket chronometer of Arnold and Earnshaw all date from this period, while verge watches remained common in cheaper production.

Watches for the Chinese and Ottoman markets
From the late eighteenth century English and Swiss makers produced watches specifically for export to China and the Ottoman Empire. For China, Fleurier houses such as Bovet, Juvet and Vrard made matching pairs of watches with richly engraved and decorated movements, often with the duplex escapement whose centre seconds hand jumps in full seconds. For Ottoman buyers, London makers such as George Prior and Markwick Markham supplied verge watches with Turkish numerals in triple or quadruple cases of tortoiseshell and silver.
These watches reflect global trade networks and the tastes of distant markets, and are important evidence for cross-cultural exchange in horology.
What to look for
- Engraved, fully decorated movements visible under a glass back.
- Duplex escapement with a jumping centre seconds hand.
- Chinese characters on the movement (e.g. the maker's name in transliteration).
- Turkish (Ottoman) numerals on the dial and multiple protective outer cases.
Dating clues
- Chinese-market Fleurier watches: c. 1820–1900.
- English Ottoman-market watches: c. 1770–1850.
