For the modern nomad, the global explorer, the individual who measures journeys in time zones and demands unwavering reliability: the LUM-TEC Combat B58 GMT, a passport to precision, meticulously crafted for every longitude and latitude.

Crafted with an unwavering commitment to robust engineering and meticulous hand assembly in Ohio, their timepieces are more than mere instruments; they are testaments to resilience, built to endure and designed to impress. The Combat B58 GMT Automatic, the latest exemplar of this uncompromising ethos, emerges as a compelling offering for the discerning global traveller and the admirer of finely engineered timepieces.

From its inception, the Combat B58 GMT is forged for action. Its 43mm case, sculpted from 316L surgical-grade stainless steel, undergoes a rigorous forging and heat-treating process before being cloaked in a titanium carbide gunmetal PVD hard coating. This robust armour not only imparts a stealthy, sophisticated aesthetic but also endows the case with exceptional scratch resistance and durability.

An anti-fingerprint coating ensures the watch maintains its pristine appearance, even amidst the rigours of daily wear. Water resistance to 200 meters further underscores its capability, rendering it a reliable companion for adventures both above and below the surface.

At the heart of the Combat B58 GMT resides the meticulously engineered Japanese Miyota 9075 True GMT automatic movement. Operating at a high-frequency of 28,800 beats per hour, this ultra-slim calibre offers exceptional precision and reliability. Its true GMT functionality, featuring independent “jump hour” setting, allows for seamless tracking of multiple time zones – an indispensable feature for the modern global citizen.

Each movement is painstakingly adjusted in six positions after assembly, ensuring maximum accuracy, a testament to LUM-TEC’s unwavering dedication to performance. An anti-shock mounting system further safeguards this intricate mechanism, enhancing its resilience in demanding environments.

The dial of the Combat B58 GMT is a study in functional elegance. Crafted from an all-metal base and finished with a bead-blasted matte PVD black coating, it provides a stark, legible backdrop for the diamond-cut premium handset. These hands, generously filled with back-filled X1 208LE Super-LumiNova, ensure exceptional low-light visibility.

LUM-TEC’s signature MDV® luminous technology, a custom-developed Grade X1 Swiss 208LE formulation, is applied to both the dial and hands, imbuing them with a vintage patina radium colour and delivering high luminous reactivity for optimal legibility in any condition. Protecting this intricate dial is a curved sapphire crystal, enhanced with a military-grade inner anti-reflective coating, ensuring clarity and scratch resistance.

Further exemplifying its robust construction, the Combat B58 GMT features a threaded solid caseback and a threaded crown equipped with double diamond seals, ensuring exceptional water tightness. High-tech Viton® gaskets contribute to the watch’s overall resilience and longevity. Recognizing the demands of diverse environments, LUM-TEC provides two military-style straps with each Combat B58 GMT: a charcoal grey nylon strap for rugged practicality and a tan leather strap with gunmetal PVD hardware for a touch of refined versatility.

The LUM-TEC Combat B58 GMT Automatic is more than just a watch; it is a limited and numbered edition, restricted to a mere 300 pieces worldwide, enhancing its exclusivity and collectability. Each timepiece is meticulously designed, hand-assembled, and fully tested in Ohio, bearing the hallmarks of American craftsmanship and precision engineering. Furthermore, LUM-TEC stands behind the enduring quality of their creation with a 2-year limited warranty and a unique lifetime offer of free timing adjustment, seal cleaning, and pressure testing.

For the discerning individual who demands unwavering performance, robust construction, and a touch of understated elegance, the LUM-TEC Combat B58 GMT Automatic is a compelling testament to American horological excellence, ready to accompany you on every journey, near or far.
