First of all, those kind are the best timepieces, filled with memories and sentiments, I am jealous :-)

I have not seen this watch anywhere before, I think it is a Rolex Ref. 4100, even if it is a 4100 this one is also unique because of the Agent's name on the dial.

If you undo the case-back I am sure you will find more stories about this watch, it's reference number, and may be some service histories.

Anyway, I am happy for you that you own such a family piece, congratulations.
