Very good specimen. Crown is not original though.

Is that a big factor in it being rare and collectible? How does that impact the value and do collectors frown on that? I really don't have a lot of knowledge when it comes to vintage watches.....I am just very fascinated with this watch because it's so rare and unique with the military time face.

Having all original is better than some parts replaced. But in general it is very desirable piece is such good condition.
What is diameter of the case? There are two versions of Aerospace Jet. Larger and smaller.
