Rare Art Deco Smiths Jump Hour - 8 Day Swiss Chrome glass - Automotive Car Clock

A rather rare little clock for a car. 

Its around 5cm square with a depth of 2.7 cm not including the bracket.

It has a square bevelled glass front with a chromed frame and adjustment / winding  knob, giving it a 1920's art deco style.

Written on the front :-

The dial itself is of the unusual jump hour  type with two windows showing the hours and minutes, the hours jump to the next.

The knob winds the clock and pulls to adjust the time.

On the rear is an adjustable bracket with two mounting holes  of 4mm diameter spaced at 30mm to the centres.

There is also a stamped serial number :-

150786

It seems to run well, but would benefit from a clean and a service. Weighs in at 300g.
