Engineered for precision and built with racing spirit, the Lum-Tec RPM 3 Chronograph is a bold fusion of motorsport inspiration and American craftsmanship. Designed and hand-assembled in Ohio, this robust timepiece features a 43mm 316L surgical-grade stainless steel case with a military-grade Titanium Carbide gunmetal PVD coating and a bead-blasted finish for added surface hardness and resilience. At just 11.3mm thick (12.3mm with crystal and caseback) and a compact 41mm lug-to-lug length, the RPM 3 offers powerful wrist presence in a surprisingly wearable form.
The multi-layered, racing-inspired matte dial is illuminated with MDV Technology® and X1 grade C3 Super-Luminova, ensuring optimal legibility in all conditions. Powered by a reliable Miyota OS20 chronograph movement, the RPM 3 delivers split-second timing performance. Additional features include a double AR-coated sapphire crystal, a threaded crown with Viton® seals, and a durable nylon military-style strap with matching gunmetal hardware. With lifetime free battery changes, seal cleaning, and pressure testing, and backed by a 2-year limited warranty, the Lum-Tec RPM 3 is more than a timepiece—it’s a high-performance machine for your wrist.
