It’s the unique serial number of that particular watch.
I think, but am not sure, that the last Army contract was 2006.

If that is the case, then I am sorry it’s not what you want to hear. Your father’s watch could be identical, newer and in better condition.
Buying old ex-military CWCs can be hit and miss. I have bought some duds in my time including an ex-navy one that had obviously been submerged and was full of rust.
