The repoussé scene to the middle case is an exceptionally fine example of embossed and chased work. It is particularly notable that the scene is executed in silver, since very few silver repoussé cases were made to such a high standard or, indeed, in such a large size. The scene is signed by one of the greatest of workers in this medium, Henry Manly (1698-c.1773). Manly was one of the 18^th century’s finest repoussé workers and came from a family steeped in the traditions of metal working – both his father and grandfather were silversmiths. Born in Augsburg, Manly moved to London, settling initially in Westminster in the 1720s, where he married Sarah Brawne in 1733, and later living in Knightsbridge. 

This is the largest recorded watch case signed by Manly and the only one in silver. The scene is the Abduction of Europa (Jupiter is seen disguised as a bull by the seashore) which, taking into account substantial changes made by Manly, probably it is from an engraving by Michel Dorigny 1617-1655 after.
