Chalfont Clocks has dated this piece to the 1870s.

The term grande sonnerie refers to the system the clock uses to strike the hours and quarters, the hour last struck is also repeated at each quarter hour, for instance at 4:15 the clock strikes once on the higher chime to indicate the quarter hour, followed by four strikes on the lower chime to indicate the hour, this is continued with two chimes on the higher gong at half past and four chimes on the lower gong to indicate the previous hour struck and three chimes on the hight to indicate the forty five minute mark plus four chimes for the previous hour. This means that you can tell the time to the nearest fifteen minutes by just listening to the clock.
This clock can also be switched to petite sonnerie, so that the clock will just strike the quarter hours but not the previous hour stuck, unless the repeat button on top is pressed when it will chime the hours and the quarters to the last fifteen minutes.

This clock was made in France in the 1870’s, but has had an interesting journey since it’s manufacture, it is stamped on the back J.E. Cauldwell & Co Philadelphia, so must have been ordered for the North American market for the retailer J.E. Cauldwell one of the most prestigious jewellers and retailers of decorative objects in 19th century America, they had a vast shop in Philadelphia (see picture) and were still trading well into the 20th Century.
