I have owned several Luminox watches before and most were the newer 45mm Evo Seal watches. I loved those watches but they were always a tad big for hunting and fitting under my camo cloths and jackets. This 3401 Nighhawk series is the perfect size (43mm) and build construction for punishing work. The rubber strap is much more comfortable than the steel bracelet and will be much more durable. The case design naturally guards the screw in crown and its round shape doesn't get caught on my cloths, gear, or bow sling.  The original design is still the best design for real work. 43mm is still large enough to fill your wrist but not too large to become a liability. Bezel feel is firm and solid. Tritium markers are bright and easy to see.  The second hand ticks away precisely and lines up with all the dial markers. The bezel also lines up perfectly with the dial markers. The screw down case lid is a must for any dive watch. Thats really what the F-117 NIGHTHAWK line of watches are. They are modified steel PVD version of the original Navy Seal watch with GMT markers on the bezel.  I love the watch and it looks good in the woods, working, or going out. A very high quality watch that is built like a tank. The watch is also licensed by Lockheed Martin. That alone is a impressive credential. I recommend.
