There's no wrong answers here, as they're both exemplary tool watches, but for me, I went with a limited edition 103 (no numerals, panda dial) and a Breitling Cosmonaute (24 hr dial kissing cousin to the 903 and Navitimer). The compromise was water resistance with the Breitling (it essentially has none), but that shortcoming is more that made up by the feeling of holding it and wearing it. It's simply indescribable.
