Combat B60 24HR Automatic

From Lum-Tec Watches

The proven, ultra-tough Combat B series has been continually evolved and improved since our original Combat B1 debuted in 2007. These watches have been battle-tested in real military applications and in the harshest environments, from scorching deserts to freezing mountaintops. The Combat B series emerges unscathed and ready for more. This longtime favorite is always ready to go. It looks great, is extremely comfortable on the wrist, supremely legible, undeniably accurate, and has proven anti-shock capability in the field. It is trusted by pilots, ground soldiers, snipers, mountain climbers, and people who appreciate a watch engineered from the ground up in the USA to perform at the highest level.

We use forged construction to realign the metal grain structure and increase fatigue strength by 37% over a typical cast steel case. This also eliminates voids and porosity in the metal, allowing for the finest possible finishing. A heat treatment is used to improve the stability of the metal during the forging process and harden the metal surface after finishing. The bead-blasted finish creates a micro-work-hardened surface that improves scratch and ding resistance by 8 to 10% over brushed or polished finishes. It leaves a flawless, smooth satin finish. We add a physical vapor-deposited anti-fingerprint coating to fill microscopic pores left by the bead blasting. This creates an even smoother surface that resists oily smudges and fingerprints. The thick, slightly domed, Hytrel-mounted sapphire creates a wider-angle reflection that makes the dial easier to see without harsh glare. Clarity is further enhanced by the military-grade anti-reflective coating applied to the inside of the sapphire. Silicone-lubricated double Viton gasket seals are used in the crown and tightly sealed threaded caseback to resist saltwater, chemicals, and extremely hot and cold environments. Our sealing system has improved by more than 200% since the original Combat B1. It is tested to exceed our 200-meter depth rating by 30%, ensuring dependable sealing in water and other harsh environments. The case has lugs that curve downward and wrap around the wrist. The 51.5mm lug-to-lug length may sound long, but much of that length comes from the steep downward curve. The watch wraps around even a small wrist without feeling oversized, wearing more like a watch with an effective lug-to-lug length of 46 to 47mm. This is one reason the Combat B case is so well-loved by thousands of owners around the world. It is extremely comfortable and barely noticeable on the wrist. Our anti-shock movement mounting system allows the movement to absorb impacts, helping maintain reliability after an accidental drop or a solid impact against a wall. Two custom-grade straps are
