The LÜM-TEC Combat B72 is a rugged quartz field watch designed for dependable everyday use, outstanding nighttime visibility, and reliable performance in demanding environments.
The B72’s defining feature is its distinctive inverse-lume dial, treated with X1-grade Swiss C3 Super-LumiNova and LÜM-TEC’s proprietary MDV® luminous technology. This creates a bold appearance during the day and exceptional legibility in dark or low-light conditions.
Built around LÜM-TEC’s proven Combat B platform, the watch combines a forged and heat-treated 316L stainless steel case with a military-grade gunmetal titanium-carbide PVD coating, anti-shock movement mounting system, curved sapphire crystal, and 200-meter water resistance.
The dependable Swiss Ronda 515 quartz movement delivers accurate, low-maintenance timekeeping. Designed, hand assembled, and fully tested in Ohio, the Combat B72 is limited to only 500 individually numbered watches worldwide.

High-Visibility Inverse Lume Dial
The Combat B72 uses a full inverse-lume dial rather than limiting the luminous material to conventional hour markers. The dial is treated with X1-grade Swiss C3 Super-LumiNova and LÜM-TEC’s proprietary MDV® luminous technology to create a broad illuminated surface in dark conditions.
The luminous material is applied in more than 30 layers over a specially treated reflective base. This construction directs the luminous output through the front of the watch, helping maximize brightness, clarity, and low-light performance.
Dependable Swiss Quartz Timekeeping
The Combat B72 is powered by the proven Swiss Ronda 515 quartz movement. Its reliable and low-maintenance design makes this watch an excellent choice for everyday wear, field use, travel, and situations where dependable timekeeping is essential.
LÜM-TEC’s lifetime complimentary battery-replacement program helps support a convenient and dependable long-term ownership experience.
Engineered for Hard Use
The Combat B72 case begins as forged surgical-grade 316L stainless steel. Forging realigns the steel’s grain structure, increases fatigue strength, and eliminates the voids and porosity that can occur in cast cases. Heat treatment further stabilizes and hardens the steel before the final finish is applied.
A bead-blasted surface produces a smooth satin appearance while improving resistance to scratches and small impacts. The military-grade gunmetal titanium-carbide PVD coating adds another protective layer, while the anti-fingerprint treatment helps resist oily marks and smudges.
Protection from the Elements
The thick, gently curved sapphire crystal provides excellent scratch resistance and a wide viewing angle. A military-grade anti-reflective coating is applied to the inside of the crystal to reduce glare without exposing the coating to external wear.
Dual Viton® crown seals, a threaded crown, and a tightly secured threaded caseback help protect the movement from water, salt, chemicals, and extreme temperatures. Every watch is pressure tested before leaving LÜM-TEC’s Ohio facility.
Comfortable and Secure Fit
The downward-curving lugs allow the 43mm case to wrap naturally around the wrist. Although the measured lug-to-lug length is 51.5mm, the pronounced curvature creates a more compact effective fit and makes the watch comfortable on a wide range of wrist sizes.
Two heavy-grade military nylon straps are included—one black and one gray—with matching gunmetal PVD hardware. Each pass-through strap runs behind both spring bars, helping keep the watch attached if one spring bar becomes damaged.
Ohio-Assembled Quality
Every LÜM-TEC watch is designed and engineered in Ohio, individually assembled by hand, and fully tested before shipment. The movement is secured within LÜM-TEC’s proprietary anti-shock mounting system to help maintain reliability following accidental drops and hard impacts.
The Combat B72 is backed by a two-year limited warranty and LÜM-TEC’s lifetime service program, including complimentary battery replacement, seal cleaning, and pressure testing.
