I am new to the watch world, but have been looking for a solid purchase with strong history of travel exploration.

I’m considering the newer bulova lunar pilot but I’m on the fence. The elgin a-11 or hamilton khaki is also a consideration, but it’s not exactly in the niche I’m itching for. The Smiths De Luxe would be my top choice if I could buy whatever I wanted since Sir Edmund Hillary used to wear it, but for a first purchase I don’t know enough to not get scammed online.

I’m hunting for watches that were used for some feats that pushed the world forward in science and exploration more specifically. Any suggestions?
