Benrus Type 3X Zulu Review: Modern Tactical Carbon GMT

The modern resurgence of historic watch brands frequently hinges on a delicate balance between archival fidelity and contemporary relevance. For several years following its revival, the legendary American watchmaker Benrus focused primarily on recreating its most celebrated historical artifacts. Meticulous reissues like the Vietnam-era DTU-2A/P field watch and the sterile Type I and Type II military divers successfully reintroduced the brand to a new generation of collectors. Yet, a brand defined entirely by past triumphs risks becoming a museum curator rather than an active innovator.

The Benrus Type 3X Zulu represents an exciting release that breaks free from simple retrospection. Developed in close consultation with retired U.S. Tier One special operations veterans, this timepiece marks the first time in its modern era that Benrus has engineered an original tool watch from the ground up. Rooted in the utilitarian principles of 1970s mil-spec procurement, the Type 3X Zulu incorporates aerospace composite carbon, lightweight titanium, and a Swiss automatic GMT caliber. The result is a watch that demonstrates Benrus is actively discovering its contemporary identity: deeply anchored in military pedigree, yet driven by modern materials and creative design.

Brand Overview: An American Pedigree Reclaiming Its Edge

Established in New York City in 1921 by three Romanian immigrant brothers (Benjamin, Oscar, and Ralph Lazrus), Benrus spent the twentieth century operating as a powerhouse of American industrial horology. Headquartered in Manhattan’s historic Hippodrome building, the firm carved out an early reputation by casing fine Swiss mechanical movements within durable, American-styled cases. From equipping early aviators with the Airman and Air Chief in the 1920s and 1930s to seeing its civilian field watch worn by Steve McQueen in the 1968 film Bullitt, the company became a fixture of twentieth-century American culture.

The cornerstone of the brand’s reputation, however, remains its storied service to the United States Department of Defense. In the 1960s, Benrus became the first manufacturer to win the military contract for the MIL-W-3818B specification, mass-producing field instruments for soldiers during the Vietnam War. In 1972, the military issued the stringent MIL-W-50717 specification for clandestine special forces operating in marine environments. Benrus responded by developing the Type I and Type II monobloc dive watches, purpose-built tools issued to Navy SEALs, UDT divers, and CIA operatives.

As detailed in this comprehensive Benrus brand history and review, the modern revival of Benrus pairs this formidable legacy with high-grade Swiss calibers from makers such as ETA, Sellita, and Soprod. The Type 3X Zulu directly advances this trajectory, demonstrating that the modern firm can translate combat-tested heritage into an advanced, modern platform.

Watch Overview

The Type 3X Zulu combines the high-pressure water integrity of a maritime diver with the multi-time-zone capability of a pilot watch. Benrus departed from traditional steel tool cases by utilizing a high-tech composite carbon and titanium structure. Rated to 20 ATM (200 meters) of water resistance and equipped with 250-gauss anti-magnetic shielding, the watch serves as an uncompromising field instrument designed for cross-meridian operations.

The Dial: Tactical Complexity with Measured Legibility

The dial of the Type 3X Zulu presents an aesthetic that is visually engaging, complex, and exciting without ever feeling cluttered or illegible. Rather than adhering to the stark, sterile dials found on archival military reissues, Benrus introduced textural depth and functional layering. The dial core features a fine, debossed square-grid pattern that effectively absorbs direct glare while creating visual contrast for the applied markers.

To retain optimal legibility in operational conditions, large geometric markers are employed throughout the dial face. Broad batons anchor the three and nine o’clock positions, complemented by circular plots at intermediate hours and an oversized downward triangle situated at 12 o’clock. These elements are generously coated with “Old Radium” Super-LumiNova. While the faux-patina hue hints subtly at historical instruments during daylight, the compound emits an intense, long-lasting green glow in dark environments.

The secondary functions are separated cleanly across the outer sectors of the dial. A military-time scale is placed along the outer rehaut, while the central orange-tipped GMT hand provides the additional time-zone indication. At 6 o’clock, a square, color-matched date window sits flush against the minute track, preserving dial balance without disrupting the visual weight of the adjacent hour plots.

Comparing the Black and Green Colorways

• Type 3X Black: The black reference embraces a monochrome tactical look. The dial displays a dark carbon-black grid surface surrounded by a tonal rehaut. The warm cream of the luminescent markers and the vibrant international orange GMT hand provide sharp points of contrast, resulting in an aesthetic that is classic, purposeful, and functional.
• Type 3X Green: The green variant is visually daring, departing from traditional olive-drab military palettes. The dial features a saturated teal-green perimeter track and matching mid-case highlights. When combined with the warm Old Radium hour markers and the dark composite carbon case, the green colorway delivers an adventurous character that emphasizes the brand’s contemporary design direction.

The Bezel: Preserving Tactical Diver Heritage

A common compromise in modern GMT tool watches is the replacement of the traditional dive bezel with a bidirectional 24-hour ring. Benrus avoided this shortcut by maintaining an operational dive bezel on the Type 3X Zulu, honoring its roots under the MIL-W-50717 diving specification.

The bezel is machined from solid titanium and incorporates a unidirectional 120-click rotation mechanism. Its insert is crafted from matte anodized aluminum, marked with a continuous elapsed-time scale featuring prominent Arabic numerals at 20, 30, 40, and 50 minutes. The zero marker features an oversized triangular sector filled with Old Radium Super-LumiNova. By preserving a dedicated 60-minute dive bezel alongside the GMT hand, the Type 3X Zulu functions simultaneously as a dive timer and an international tracker. The aggressive coin-edge machining along the titanium outer ring provides tactile grip, turning with firm, tactile resistance and zero mechanical backlash.

Case Engineering and Wearability: The 42 mm Footprint

On paper, a case diameter of 42.0 mm can appear intimidating to collectors who prefer vintage sizing or have smaller wrists. However, the case architecture of the Type 3X Zulu reveals an ergonomic design that wears far more compactly than its diameter suggests.

A critical element of this wearability is the short effective lug-to-lug distance, approximately 46.0 mm to 46.5 mm. Benrus does not publish a traditional tip-to-tip lug dimension in its specifications, so this should be treated as an approximate figure rather than an official measurement. Benrus engineered the watch with hooded, truncated lugs that end almost flush with the outer perimeter of the rotating bezel. Because the lugs do not extend far outward, the strap articulates downward close to the edge of the case. This compact lug geometry helps the watch suit smaller wrists, although the final fit still depends on wrist shape and strap adjustment.

The materials chosen for the case further enhance its wrist comfort. The mid-case is constructed from forged composite carbon, paired with a titanium inner chassis, titanium screw-down crown, and titanium caseback. This composite arrangement dramatically lowers the total mass compared to stainless steel, preventing top-heavy wobble. The 12.50 mm profile remains impressively slim for an automatic GMT dive watch with 200 meters of water resistance, easily fitting underneath jacket cuffs.

The screw-down crown at 3 o’clock is partly guarded by subtle case fluting, protecting against impacts while remaining easy to manipulate. The solid titanium caseback is secured by four screws and bears deep military-style engravings alongside the Benrus crest and technical markings.

Movement: The Proven Reliability of the ETA 2893-2

Inside the composite case sits a great movement: the Swiss Made ETA 2893-2 automatic GMT caliber. Operating on ETA’s premium 2892-A2 slim movement architecture, this caliber provides a robust foundation for a tactical instrument.

The ETA 2893-2 functions as an independent quickset GMT, commonly referred to by collectors as a “caller” movement. In the quickset crown position, rotating the crown in one direction advances the date, while rotating it in the opposite direction advances the orange 24-hour hand in independent one-hour increments. The primary local timekeeping hands run continuously during those adjustments, while the hacking seconds feature enables precise down-to-the-second synchronization when setting the time.

The choice of the ETA 2893-2 aligns well with the watch’s technical focus. Because it measures only 4.10 mm thick, Benrus was able to keep the complete watch height down to 12.50 mm despite its 200-meter depth rating. The ETA caliber also offers long-term durability, shock resistance, and widespread serviceability, providing a familiar platform for qualified watchmakers to maintain over time.

Strap System and Field Usability

Benrus equips the Type 3X Zulu with a comprehensive two-strap package, taking advantage of its standard 20 mm lug width.

The primary strap is a heavy-duty hook-and-loop fabric wrap inspired by military aviator bands. On the black version, the strap is rendered in desert tan, offering a sharp field contrast against the dark case, while on the green one, the fabric is dyed to match the teal-green dial track and mid-case accents. The hook-and-loop design allows micro-adjustability, enabling the watch to fit securely over damp wetsuits or tactical jackets.

For daily office and casual wear, the included black rubber strap offers a more streamlined look. It features a supple, dust-resistant texture that wraps comfortably around the wrist, secured by a brushed titanium pin buckle. The rubber strap keeps the watch positioned securely on the wrist, further accentuating the compact nature of the hooded lugs.
