I just had the honor of spending a lot of time with a bunch of GIs. I'm not talking rear-echelon guys but real war fighters. Many with Ranger tabs on their shoulder and multiple combat tours under their belt. And I couldn't help but notice that not one wore a "tactical" watch or anything meant to conjure up any sort of military association. Instead they wore cheap black plastic/resin Casio or Timex Ironman watches. One tough sergeant wore an Adidas brand digital watch. Black and very utilitarian looking.
I love mechanical watches as much as the next guy, but sometimes it's good to get a reality check.
