movement 7AK dated 1946 ( square symbol ) , 21 jewels. Case 10k gold filled number 8466689. Checked data base nearest to case is a 1948 his excellency.
Have been through the ads as well and found nothing , it does not appear that the case was in issue until about 1948 , its the usual situation , is it an unknown or some one went into a jewellers store and liked the case but preferred the X face , who knows. Its unusual that the case appears newer than the movement , its usually the other way round.
I would guess there was more flexibility in those days to switch movements and cases around to suit the customer.

Just continuing from the above , I am surprised that there are no records on the watch numbers. I would have thought that for example there would be a run of numbers for a particular model and these would be recorded. this is also important for stock record purposes to ensure no pilfering of stock. If the numbers were never used for any stock control or model inventory , why go to the expense of numbering them ?
