Practical Day-Date Display
The Miyota 2105 quartz movement delivers dependable accuracy with minimal maintenance. Separate day and date indicators make important calendar information immediately visible, adding everyday convenience for work, travel, and outdoor use.
With approximately three years of battery life and LÜM-TEC’s lifetime complimentary battery-replacement program, the B68 provides a practical and dependable long-term ownership experience.
Engineered for Hard Use
The Combat B68 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.
Exceptional Low-Light Visibility
The matte-gray dial and premium diamond-cut hands are treated with LÜM-TEC’s proprietary MDV® luminous technology. More than 30 layers of custom X1-grade Swiss C3 Super-LumiNova are applied over a specially treated reflective base.
This construction directs the luminous output through the front of the watch instead of allowing it to dissipate behind the dial, producing a powerful green glow and excellent visibility in dark and low-light conditions.
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.
Silicone-lubricated Viton® 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 B68 Day-Date is backed by a two-year limited warranty and LÜM-TEC’s lifetime service program, including complimentary battery replacement, seal cleaning, and pressure testing.
