I am a chemical engineer who has always been interested in space/astronomy, so honestly somewhat similar mindset as your brother since all of my owned/wanted watches are somewhat space themed.
I feel like the “Easy” answer is the Hamilton Murph like others have said. Interstellar is my favorite movie and I’m sure as an aero engineer your brother might share a fondness for the movie.
My last purchase was the new white Casio NASA collab. Super cheap but not sure if it was a limited run or not.
In addition I think a moon phase watch would be a nice little “space” feature, and one that I’ve had my eye on is the Engineer II moon phase from Ball. Pretty pricy but a step up from the Murph.
