My son is thoroughly enjoying Khaki Field King Day-Date 40mm. As a high school graduate this is his first watch. Love that it’s automatic and being able to see the mechanical movement through the back case is awesome. A great piece is suspect he’ll keep a lifetime and pass down.

The website can't capture the true look and sophistication of this simple piece. The look and feel once it was on the wrist absolutely exceeded all expectations. The leather strap is probably the nicest strap I have ever worn myself and the engraving I requested just made the piece so personal to me. The fit on my wrist is perfect fory wrist size and I've received a ton of compliments and questions about the brand since sporting it at work and in my daily life.

Quality is same, Lume is unacceptable and pitiful, leather strap is way to stiff, Blue dial is brilliant and mesmerizing.
