Produced between 2014 and 2018, this example represents the full-featured apex of Luminox's collaboration with the survivalist and TV presenter Bear Grylls. It wears on a grey nylon canvas strap with rubber backing, ready for immediate use straight from the box.
Movement: QUARTZ (Ronda 515.24H). Case: Stainless steel with black carbon compound case, 45 mm.Bracelet: Nylon / canvas with rubber backing. The Luminox and Bear Grylls Partnership Luminox has built its reputation supplying purpose-driven timepieces to military, law enforcement, and outdoor professionals since the early 1990s, beginning with its iconic Navy SEAL series.
The Bear Grylls Survival Series, launched in collaboration with the British adventurer and former SAS soldier, was a natural extension of that ethos. Grylls - known globally for his television series Man vs. Wild and his role as Chief Scout - was a credible partner for a tool-watch brand, and the XB series reflected genuine input on functionality rather than a purely cosmetic endorsement deal.The collaboration ran from 2014 through 2018, giving the series a relatively focused production window. 3761 - World Time GMT Within the Bear Grylls lineup, the XB. 3761 sits at the top of the functional hierarchy. The rotating world time bezel engraved with city names - including Hereford, a nod to the home of the British SAS - works in concert with a dedicated GMT hand to allow simultaneous tracking of two time zones. The Ronda 515.24H quartz movement powering the watch is a Swiss-made calibre chosen specifically for its reliability across extreme temperature ranges, an important consideration given the survival context of the series.
The orange crown at 3 o'clock and the matching orange GMT hand provide immediate visual contrast against the black dial, a practical choice for legibility under field conditions. Construction and Materials The 45 mm case pairs a stainless steel main structure with a black carbon compound bezel insert, a material choice that reduces rotating mass and resists scratching better than a standard polymer. Luminox's signature self-powered tritium gas tube illumination - embedded in the hour markers and hands - provides consistent low-light legibility without requiring wrist movement or ambient light charging, distinguishing it from lume-painted alternatives. The grey nylon canvas strap with moulded rubber backing is appropriately tactical and comfortable across extended wear, and the stainless steel deployant clasp with Luminox branding ensures the watch stays secure under active use. 3761 with complete box and papers are increasingly uncommon given that production closed in 2018.
The quartz movement means no accuracy drift and no servicing requirement for years of normal use. Collectors interested in tool watches, military-adjacent horology, or the broader category of purpose-built field watches will find the XB series an honest and underappreciated corner of the market. Comparable References Within the Luminox catalogue, the XB.3761 is most directly comparable to the XB. 3741 chronograph variant from the same Bear Grylls series, which trades the world time complication for a stopwatch function.
Buyers considering this piece from outside the Luminox ecosystem might also look at the Timex Expedition North or the Citizen Promaster Land GMT, though neither offers tritium tube illumination at comparable price points. 3761 occupies a specific and well-defined niche: a genuine GMT with always-on illumination, built for use rather than display.
