Hamilton Khaki Air Race 38mm. This is the much more desirable and wearable 38mm, not the 42mm. The numbers are slightly recessed, giving the watch a Sandwich dial appearance that is very subtle, but quite nice. I bought this watch because I like the "Halloween" vibes to it. I wore it less than 5 times. Turns out that I do not like orange very well. The first two pictures are stock Hamilton pictures, the last three are of the actual watch. If you have any questions, please ask. As the Official Timekeeper of the Red Bull Air Race, Hamilton is proud to introduce the special edition Khaki Air Race. The orange and black Team Hamilton version reflects the colors of Nicolas Ivanoff's race plane and the blue, gray and red Official Timekeeper model honors the official colors of the Red Bull Air Race. Each model is available with a choice of leather strap or metal bracelet and is presented in a 38mm case.
