Help dating watch please! *COMPLETED*

Hi Rootschatters!

Can you please help me date this little gold watch?

Face is 2.5cms/1 inch diam, on a black ribbon with gold clasp.

There are 3 stamps on the inside but I cannot get a clear enough photo so have had to draw the symbols - apologies for my poor drawing quality. The first stamp is a small "n" within a circle; the second stamp is for 9ct gold; and the third stamp is like a crosshair within a square, and what looks like a very feint "L" within the circle. I have tried to date it by looking up the stamps but got completely confused - there doesn't seem to be an assay office stamp on the watch, or at least not one that I can recognise.

Any help very much appreciated!
