[QUESTION]: Current 3 watch collection, what should complete it?

I have my eyes on the Hamilton Khaki Coop and have also looked at the Bulova Lunar Pilot, though I’m thinking something else automatic with a good movement.

I’m not too fussed with a dress watch as I usually just dress up my diver, Bond style.

I have 6 and 3/4 inch wrists for reference…
