Thanks Mark!

The caseback is steel. I'll get the caseback off and take better pictures of markings though.

Thanks,
Rahil

: Ok, so the oval pushers say 30s or 40s, but the deeper shield
: didn't come along until the latter. So probably some time from
: the 40s.

: I can't find a match for model or dial, but the movement is
: definitely genuine and the dial looks ok in the shot of the
: front too. From what we have to go on, I'd say genuine Heuer but
: I can't narrow the model down for you unfortunately.

: Is the case solid gold or gold-filled? There should be markings on
: the inside of the caseback (which should also be gold) if it is
: solid gold. It could be 14 or 18K at that time.
