Lum-Tec RPM 3 Watch – USA Assembled Chronograph with MDV Lume – CGA Watches

The RPM 3 is Lum-Tec's racing-inspired chronograph, built for the track and the field. A 43mm 316L surgical-grade stainless steel case gets a bead-blast finish and a military-grade titanium carbide gunmetal PVD hard coating for serious durability. It's powered by a Miyota Japan OS20 chronograph movement, protected by thick sapphire with double-sided military-grade AR coating, and sealed with a bolt-on solid 316L caseback plus a threaded crown with double Viton seals — rated to 50 meters.

The dial is a three-layer racing-inspired design with a matte finish, green-glow X1 grade C3 Super-Luminova, and premium diamond-cut hands with matching lume, all using Lum-Tec's patented MDV luminous technology. It ships on a nylon two-piece military-style strap with matched gunmetal PVD hardware, and every unit is designed, assembled by hand, and fully tested in Ohio.
