··Purrrr-veyor of luxury cat box loungersSo it is actually a 168.004. Nice.
strictly speaking yes and no.
It is a .5004, a British version of an .004
The last Swiss versions of an .004 were sold around '67 (IIRC), superseded by the 168.010 - as you first thought of your watch.
But the British liked to tarry somewhat, in design terms, which is why you also see British 'lyre-lug' Connies being produced right through the 60s, even though they stopped officially being produced (in Switzerland) in around '62
These are very good quality cases, the equal of the Swiss cases
Still doesn't explain the 'missing' medallion though.....
