Lum-Tec RPM 3 Watch

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. 316L Surgical grade Stainless Steel case Bead blast finish for extra durability Military grade Titanium Carbide gunmetal PVD hard coating 43mm case width 20mm lug width 41mm lug to lug length 11.3mm case thickness (12.3mm total with sapphire and caseback) 50 meters water resistance Miyota Japan OS20 chronograph movement Thick sapphire with double side military grade AR coating bolt-on solid 316L Stainless Steel caseback Threaded crown with double Viton® seals.
