The Duties on Clocks and Watches Act 1797 (38 Geo. III, c. 108) was an Act passed by the Parliament of Great Britain, instituting a tax on clocks and watches. The tax nearly ruined the manufacturers of clocks and watches as demand decreased considerably so that in less than a year the production of these had been reduced by a half, with thousands of people made unemployed. The tax was thus repealed within a year, in April 1798.
