The Original Lüm-Tec OEM Rubber Strap with PVD Buckle 22mm, 24mm and 26mm straps I have not been impressed

I have not been impressed with Luminox watches in the past but this watch is well made and the carbon fiber case is very cool

Marathon watch is the only current Government issue watch but this Luminox is indeed a well-made timepiece and does use Tritium tube illumination

The steel back has full military markings

The Original Lüm-Tec OEM Rubber Strap with PVD Buckle 22mm, 24mm and 26mm straps I have not been impressedCAD engineered to provide strength, and flexibility, as well as great looks! The rubber is anti static, and is firm and "dry" to the touch, yet very flexible by design, not by soft rubber compound. 26 22mm, 24 22mm or 22 22mm. It will adjust to fit from a 6. 5" wrist size to an 8. 5" wrist. 22mm black PVD buckle with LUM TEC engraving is included.
