About this entry

87% of key specs known. Missing: weight, bracelet offered.

Sold as "Combat B68 Day Date". Limited and numbered series of 500. Miyota 2105 quartz with day and date at 3, 3-year battery. Anti-reflective matte B-Uhr style dial (minute numerals, triangle at 12). Brand specs: 43mm, 13.6mm including the domed sapphire, 51.5mm lug-to-lug, 22mm lugs, 200 m, threaded solid steel caseback (solid per the brand's caseback photos). Titanium carbide PVD hard coating in gunmetal (no hardness given). Inner anti-reflective coating on the sapphire. MDV Luminous Technology, per the brand: the dial is printed with over 30 layers of Super-LumiNova over a chemically coated reflective base so the glow is directed out of the front rather than lost into the dial, and RC Tritec in Switzerland tested and verified its dials as top performers. Brand case claims: forged 316L (forging said to raise fatigue strength 37% over a cast case), heat treatment "to increase metal hardness" (not recorded as hardening: no surface treatment or hardness is given), bead-blast finish said to improve scratch resistance by 8-10%, PVD anti-fingerprint coating, double Viton gaskets in the threaded crown and caseback, tested to 30% beyond the 200 m rating. The lugs curve down steeply; the brand says the 51.5mm lug-to-lug wears like a 46-47mm one. Fixed knurled (coin- edge) bezel and no crown guards, from the brand's photos. The included straps are pass-through nylon military straps that loop through both spring bars. No bracelet comes with the watch; Lüm-Tec sells Combat B bracelets separately as accessories. Weight is not published. The spec list calls the dial "anti-reflective matte gray"; it looks black in the photos. The spec list says only "military-grade AR coating"; the description puts it on the inside of the sapphire. The B68 is the gunmetal, C3-lumed counterpart of the B67. Listing created December 2025, published on the store in January 2026.
