Bought this from a Gloucester military dealer who described it as a Spitfire clock?? ... was not working .. now serviced and keeping good time ... watchmaker said it has an ABEC escapement and that movement is probably a Smiths ... has bezel wind ... unfortunately watchmaker could not replace the slot-worn screws in the bezel ... did not ask him to replace the glass ... so is as found with 65 years wabi

Dial is engraved with following but is difficult to photograph through the discoloured glass

MK IIA 594/43 (across the centre of the dial)

and
6A/1002
ONE DAY

across bottom of dial between 8 and 4

Rear of case stamped AM




These are camera phone pix.
