Hi. I can see that you are a long term member. So I assume taking the case back off to get the ref no is difficult and you a already know that those dogleg lugs have been polished unrecognisable.
Pics aren’t great but - Looks like a late 60s 167.005 with painted indices, some of which are faded.
Would need to see the hallmarks to know if it is 18k or 14k gold.
