The LÜM-TEC Combat Field X4 is a lightweight titanium automatic field watch designed for travel, everyday wear, outdoor use, and reliable performance in demanding environments.
The X4 is powered by a precision-tuned Miyota 9075 Japanese automatic movement with an independently adjustable hour hand. The movement is adjusted in six positions after assembly and secured within LÜM-TEC’s proprietary anti-shock mounting system.
Its forged and heat-treated Grade 2 titanium case features a bead-blasted finish and gunmetal titanium-carbide PVD hard coating. A forged carbon-fiber dial, tall curved sapphire crystal, sapphire exhibition caseback, and green-glowing MDV® luminous technology give the X4 a distinctive technical appearance.
Designed and hand assembled in Ohio, the Combat Field X4 Titanium is limited to only 500 individually numbered watches worldwide.

Precision Automatic Performance
The Combat Field X4 is powered by the high-precision Miyota 9075 automatic movement. Its independently adjustable hour hand makes changing the displayed local time faster and more convenient when traveling or moving between time zones.
Each movement is adjusted in six positions after the watch is fully assembled. The sapphire exhibition caseback provides a clear view of the mechanical movement in operation.
Lightweight Titanium Construction
The X4’s case is forged from Grade 2 titanium and heat treated for increased strength and stability. Titanium provides excellent durability while keeping the 44mm watch lighter and more comfortable than a comparable stainless steel design.
A bead-blasted finish gives the case a refined satin appearance. The gunmetal titanium-carbide PVD coating adds a protective surface layer and complements the technical texture of the forged carbon-fiber dial.
Forged Carbon-Fiber Dial
The forged carbon-fiber dial gives each Combat Field X4 a distinctive patterned appearance. Unlike a conventional woven carbon-fiber design, forged carbon produces an irregular marbled texture that reinforces the watch’s modern, performance-focused character.
Premium diamond-cut hands provide crisp contrast against the dial and are filled with X1-grade Swiss C3 Super-LumiNova for dependable low-light visibility.
Maximum Darkness Visibility
LÜM-TEC’s proprietary MDV® luminous technology uses 30 layers of custom X1-grade Swiss C3 Super-LumiNova. The luminous treatment produces a powerful green glow for excellent visibility in dark and low-light environments.
Protection from the Elements
The double-high curved sapphire crystal provides excellent scratch resistance and gives the watch a distinctive vintage field-watch profile. Its military-grade anti-reflective coating reduces glare and improves dial clarity.
A screw-lock crown with LÜM-TEC’s dual diamond sealing system and high-performance Viton® gaskets help protect the movement from moisture and environmental exposure. The completed watch is rated for 100 meters, or 330 feet, of water resistance.
Two Military-Style Straps Included
The Combat Field X4 includes two strap options: a gray nylon military strap for lightweight field use and a brown leather military strap for a more traditional appearance. Both feature 316L stainless steel hardware finished with matching gunmetal PVD coating.
Ohio-Assembled Quality
Every Combat Field X4 is assembled by hand in Ohio and fully tested before shipment. The movement is secured within LÜM-TEC’s proprietary anti-shock mounting system to help maintain reliability following accidental impacts.
The watch includes complimentary lifetime movement regulation, pressure testing, and seal lubrication and cleaning. It is also backed by a fully transferable two-year international limited warranty.
