Yes this one,
Yes this one,
1978 was a very sparse year for MOD issued watches.
1. CWC W10 marked 0552 as seen above, but quite rare, perhaps only 150 issued
2. CWC 2-Button Chronograph - about 300 issued, marked 6BB
3. CWC stopwatches - small batch of 1/5 second stopwatches marked W10 and 0552
Good luck with the search.
