Lot Essay

This instrument would appear to have been designed as a 'counter display' advertising Zenith watches. A very unusual feature is that the movement can only be wound, and the hands set, by turning the bezel. Another particularly unusual feature is the mechanism for adjusting the distance apart of the curb pins.
