A full plate key wound and set movement by Ehrhardt for Brooks Banks, signed by the later and with the formers trademark under the dial. It has a tangential Swiss Lever escapement, 7 jewels and an under-sprung solid balance. It winds anticlockwise (as were English Fusee watches) by the use of gearing under the dial. It is set from the front by using the key on the "hub" holding the hands.
The English Consular type "swing out" case has Birmingham hallmarks for Sterling Silver, 1892 and the makers mark of William Ehrhardt. It has been ultrasonically cleaned and has a new crystal.
