Julien Le Roy à Paris. A group of 3 movements which demonstrate the development of his improvements concerning the repeating work of watches.
In 1740 he devised a new arrangement allowing the enlargement of the area for the repeating work. This invention, called à b â t e l e v é e , was adopted by all his fellow watchmakers. In 1755 he devised a nere repeating train regulated by a small anchor escapement which was also adopted by the best of French watchmakers. The dates for these two inventions are engraved on the dia] plates. They are useful to date the watches with precision. Julien Le Roy à Paris No. 1827.
