Winds and ticks away fine, but there is a problem, so sold for SPARES OR REPAIR, NO RETURNS.  Key wind and adjust and the sub seconds hand ticks away perfectly for the whole wind. But the hour and minute hands only work intermittently. Sometimes they will move for an hour or so. Sometimes not at all . Bit of an odd one.  Case with full English import mark for London 1912. Surface wear/minor denting commensurate with age and use. Push button release and the sprung loaded back pops open automatically as it should. Enamel dial in good order with no cracks.  Key wind and adjust. Key NOT included. Please see picture with ruler for size.  SOLD WITH NO RESERVE
