What a beautiful chronograph!!

So that we can more easily study the differences, I am posting your photo together with the photo of my black-on-black 73663.

Looking at these photos, I think that I prefer the cleaner design of yours (markers instead of numerals), but I like the color scheme of mine (green accent, rather than tan). Maybe your is better with the khaki suit and mine better with the olive suit? (Interesting to note that over the years, military camouflage has shifted from green (forests and jungles) to sand (desert) . . . corresponding to these two chronographs?)

Congratulations on the fantastic "find"!!
