According to the Archives of Audemars Piguet, the movement of the present watch was sold to J.W. Benson.
According to their publicity, J.W. Benson was founded in 1749 and one of England's leading watchmakers located in London. James William Benson, who in 1865 described himself as Watchmaker to the Prince of Wales, made and retailed a wide range of models, which were mainly produced by specialist outworkers around the city and from abroad.
The present watch is a wonderful example for such a watch, fitted with an Audemars Piguet ébauche and a massive case stamped FT for Fred Thoms and the off-white dial possibly made by Frederick Willis. Thoms and Willis are renowned for their high quality cases and dials which he supplied to the best English watchmakers for their most prestigious pieces.
