I’ve searched online as much as I can and can’t find reference to this anywhere.

I was given this watch as a 10th birthday present in 1978, purchased from a jewellers in London.

(I realise it’s in the wrong Casio box)

I recognize the odyssey name but havent seen that odyssey before. although Im pretty sure I have seen the case design on something else. Maybe it a hong kong watch branded for Odyssey. Are there any more clues on the case back? Have you had it working yet?

Just found this on the net, which is where I have seen the case, on a Beltime.

The Dixons own brand watches were badged as “Odyssey” They were manufactured using Beltime parts and occasionally pop up on E-bay, though they are usually Beltime branded.

Thanks for the quick reply Adam. You were correct about Hong Kong, attached is a photo of the back.
I haven’t tested it yet - I will try and find a battery tomorrow.
