I bought a Hamilton Field Khaki Auto Titanium, and I couldn't be happier with the purchase. The watch is very versatile, much more than my Nite MX10 it replaces, since it looks classy for everyday wear. Hamiltons are well built, light, and still plenty tough.
The only thing that lets it down is the lack of tritium illumination, which, if present, would make the watch a perfect everyday companion. This feature is already available on Nite Atlas models, and will be hard to live without.
