Quiet Street Antiques of Bath has dated this piece to the 19th Century.

A rare clock, with a patented winding mechanism from Leroy & Fils which was quite ingenious. The large winding key is permanently affixed to the base. Turned in one direction, it will wind the going side of the clock, in the other direction it will wind the strike side. Thus a forwards/ backwards wrist motion winds both sides. And there is no need to find the key first. This design was patented by Leroy (patent number 9501), and the key is so signed. Numbered case 5652.
Date: c.1880
