Help identifying watch

Hi, would someone be able to help with identifying this watch? It looks like an RAF camera watch from what I have been able to gleam from the internet, although the seriel number on the reverse is different to others I have seen, plus there is no N number as with others. Any help would be greatly appreaciated!

Hi jcolch,

yes that looks like the camera watch for the RAF bombers. There are specialist collectors on this forum that can provide mor info this instrument. It should be equipped with a Caliber 89 movement and the dial printing is very fragile from what i know.
