Lum-Tec Combat B69 Automatic | USA Assembled Field Watch with MDV Lume

The Combat B69 is part of Lum-Tec's Combat B series, the field watch line Lum-Tec has kept refining since the first Combat B1 arrived in 2007. Lum-Tec says Combat B watches have been battle tested in real military applications and in environments from deserts to freezing mountaintops, and that they are trusted by pilots, ground soldiers, snipers and mountain climbers. Lum-Tec says the Combat B is comfortable on the wrist, legible and accurate, and that its anti-shock capability is well proven in the field.

The B69 is the automatic version of the Combat B in a gunmetal finish. A Japanese Miyota 9015 runs at 28,800 beats per hour, can be wound by hand and hacks so you can set it to the second, and Lum-Tec regulates it in six positions in-house; a sapphire window in the caseback lets you watch it work. The forged, heat-treated 43 mm case is bead blasted and then given a gunmetal titanium carbide PVD hard coat, and the matte black dial and diamond-cut hands use X1-grade C3 Super-Luminova as part of Lum-Tec's MDV® luminous technology. It is rated to 200 meters and limited to 500 pieces.

As an authorized Lum-Tec dealer, The CGA Company sells the B69 new, never pre-owned, with free USA shipping. Black and gray nylon straps are included, and it is a limited, numbered series of 500 worldwide.

Construction

The case is forged 316L steel, heat treated, bead blasted and finished in a gunmetal titanium carbide PVD hard coat. Lum-Tec says forging adds about 37% fatigue strength over a cast case, and that the bead-blast finish creates a micro work-hardened surface that improves scratch and ding resistance by 8-10%. An anti-shock mount helps the automatic movement take knocks.

The domed sapphire on the front is Hytrel mounted and AR coated on the inside, and a second sapphire window in the threaded caseback shows the movement. The crown and caseback use silicone-lubricated double Viton® seals, which Lum-Tec says are tested to 30% beyond the 200 m rating.

Heat treatment does two jobs on this case: it keeps the steel stable while it is being forged and hardens the surface once finishing is done. The glare-cutting layer on the inside of the sapphire is a military-grade DLC anti-reflective coating. The case seals are there to stand up to salt water, chemicals and very hot or very cold conditions, not just water pressure, and if the watch is dropped on a hard floor or knocked against a wall, the anti-shock mount lets the movement absorb the hit.

Fit and Straps

The lugs angle down sharply, so the 51.5 mm lug-to-lug wears like roughly 46-47 mm, according to Lum-Tec. Two heavy nylon straps come with it, one black and one gray, both with gunmetal PVD hardware. Each strap runs under both spring bars, so the watch stays on if a spring bar fails.

Lum-Tec says its nylon straps are more durable than typical straps of this type and are designed for easy adjustment, a secure fit and minimal weight on the wrist.

MDV® Lume

The matte black dial and the diamond-cut hands both use X1-grade C3 Super-Luminova as part of Lum-Tec's MDV® luminous technology. On the dial it is printed in more than 30 layers over a reflective base. Lum-Tec says RcTritec in Switzerland verified its dials as top Super-Luminova performers.

Lifetime Service

Because the B69 is an automatic, its lifetime services are free timing adjustment, seal cleaning and pressure testing, all done by Lum-Tec in Ohio. Lum-Tec says it regularly sees its watches come back for service after 15 or more years of use, and it puts what it learns from them into new designs. Lifetime services are provided by Lum-Tec under Lum-Tec's terms, not by The CGA Company; for service, contact service@lum-tec.com.

Lum-Tec says its watches are designed and engineered in Ohio from the ground up, and every Combat B69 is hand assembled and individually tested in Mentor, Ohio, using international and domestic components; the movement in this model is the Japanese Miyota 9015 automatic. After assembly, the movement's timing is adjusted in six positions. Lum-Tec says that since 2007 it has produced watches for more than 100 brands around the world, the U.S. government and SWAT teams.
