A rare early Wall Clock by Holden

Oak case with partly glazed door
Size: 23 inches high and approx 9.5 inches wide overall.

A very early battery operated movement in which a coil swings between the poles of a pair of permanent magnets operating a contact as it passes the centre line in each direction.

Frank Holden patented his design for the electric clock in 1909. The clocks were in all probability manufactured in France and carried the signatures of Rebesi, Regina or Apollo.
Table models of Holden clocks are sought after and fetch high prices, both in the UK and the US. This is despite the fact that these clocks are not highly thought of as timekeepers. Wall models are much less common and, personally I only know of one other which was in Holland until recently.
The dial of mine has, in addition to Regina, "Bte S.G.D.G." , "A.S.E.M. Paris" and a small inscription indicating that the dial was Swiss made.
I understand that there is a brief reference to the work of Frank Holden in Hope Jones' book "Electrical Timekeeping". There is also a descriptive page in the Science Museum Catalogue of the "Electrifying Time" exhibition.
