Marathon Jeep Watch Review: 2 Top Models for Military Watch Enthusiasts

Military-inspired timepieces have long been valued for their practical design, clear legibility, and ability to withstand demanding conditions. These characteristics have shaped the development of purpose-built watches, particularly those created with military specifications in mind. Today, the same design philosophy continues to attract watch enthusiasts who appreciate timepieces that prioritize function without sacrificing distinctive character.

The Marathon Jeep Watch collection reflects this approach through a combination of rugged construction, functional details, and heritage-inspired aesthetics. Developed by Marathon Watch in collaboration with Jeep, the series takes cues from the iconic Willys MB and Wrangler Rubicon, two vehicles that represent different chapters of Jeep's rugged legacy. The collection also draws on Marathon's long history of producing timepieces associated with military use, giving its designs a deeper connection to the world of the military watch.

Beyond their military-inspired appearance, the watches offer distinct specifications that make each model worth examining more closely. From their case construction and luminous features to their mechanical movements and practical straps, the details reveal how Marathon translates its heritage into contemporary timepieces. Let's explore the Marathon Jeep collection and discover the standout models that deserve a closer look.

An Introduction to the Marathon Jeep Series

The Marathon Jeep Series brings together two names with strong connections to military heritage, practical engineering, and dependable performance. Developed through the collaboration between Marathon Watch and Jeep, the collection translates the rugged character associated with military vehicles into functional timepieces. Rather than focusing purely on aesthetics, the series reflects a shared philosophy in which durability and purpose remain central to the design.

The concept behind the collection draws from two significant chapters in Jeep's history: the Willys MB and the modern Wrangler Rubicon. The Willys MB holds a special place in the brand's heritage as the military vehicle produced for the U.S. Army during World War II, while the Wrangler Rubicon represents Jeep's continued reputation for tackling demanding terrain. These two vehicles provide a natural foundation for a watch collection built around resilience and utility.

This military influence also connects closely with Marathon's own background. Although the brand may be less familiar to casual watch enthusiasts, Marathon has established a strong reputation among collectors interested in military timepieces. Its watches have been produced for military use, including for the United States and Canadian armed forces, giving the brand decades of experience in creating instruments designed to perform under demanding conditions.

Marathon's roots stretch back further than its military watchmaking legacy. The company traces its beginnings to 1904, when it operated as Weinsturm Watch before becoming Wein Brothers. Morris Wein later established Marathon Watch in 1939, continuing the family's involvement in precision timekeeping. From the 1940s onward, the company expanded its work with timing instruments for Allied Forces, laying the foundation for the military-oriented expertise that continues to define the brand today.

The Marathon Jeep Series builds on this heritage by drawing from the functional military watches developed for Allied forces in the early 1940s. Its design language also recalls the lineage of military specifications such as the GG-W-113 watches that became associated with U.S. military field watches during the 1960s. This historical influence gives the collection more depth, as its utilitarian appearance is rooted in the practical requirements that shaped military timepieces rather than being purely a modern styling choice.

At the same time, the collection demonstrates how military-inspired watchmaking can be reinterpreted for contemporary wear. The Jeep connection adds an automotive dimension to Marathon's established tool-watch identity, while the Swiss manufacturer's engineering background supports the watches' emphasis on reliability and precision. As a result, the series serves as a meeting point between Jeep's rugged automotive heritage and Marathon's long-standing tradition of producing purpose-driven watches.

Marathon Jeep Watch Review: Top 2 Picks by Gnomon Watches

The rugged character of Jeep’s iconic vehicles serves as the inspiration behind a collection of watches designed around durability and practicality. Paired with Marathon’s military watchmaking heritage, the Jeep collaboration delivers timepieces that emphasize legibility, robust construction, and purposeful design.

In this Marathon watch review, we take a closer look at two standout models from the collection. Although both belong to the Marathon Jeep watch lineup, they offer different approaches to case design, movement, and everyday functionality. Below, explore the two models selected by Gnomon Watches.

1. Marathon Jeep Willys SSSGPM Officer’s Mechanical

The Marathon Jeep Willys SSGPM Officer’s Mechanical takes inspiration from the General Purpose field watches issued to Allied forces during World War II. Its design stays close to the practical character expected from a military timepiece while introducing a more contemporary case profile. Measuring 41mm in diameter, 48mm from lug to lug, and 11mm thick, the watch has a substantial presence without appearing unnecessarily bulky. Its 316L stainless steel case receives a fully matte finish, helping minimize reflections while reinforcing its utilitarian character.

One of the most distinctive aspects of the case lies in its unconventional silhouette. Instead of using a conventional bezel and crown guard, the SSGPM features a bezel-less and asymmetrical construction that gives the watch a cleaner appearance. The short, integrated-looking lugs contribute to its compact proportions, while the wider profile on one side creates a more pronounced tactical character when viewed from above. This unusual construction also leaves the pressure crown easier to access, adding a practical touch to the otherwise minimalist design.

The black dial continues the watch's military-inspired approach with a straightforward layout that prioritizes legibility. Its numerals feature an Aged-Radium color treatment, giving the dial a vintage appearance inspired by earlier military watches. Sword-shaped hour and minute hands are paired with a red seconds hand, creating a subtle contrast against the black background. The Jeep logo occupies the 12 o'clock position, while the Marathon branding and mechanical movement details sit at 6 o'clock. A minute track around the perimeter completes the functional layout, protected by a flat sapphire crystal.

Visibility in different lighting conditions receives additional attention through Marathon's luminous technology. The dial uses MaraGlo to illuminate the hands and markers, supporting quick time reading when ambient light is limited. This practical focus fits naturally with the field-watch concept, where legibility remains more important than decorative detailing. Combined with the black dial and aged-color numerals, the luminous treatment also helps preserve the vintage military character without making the overall design feel dated.

Powering the watch is the hand-wound Sellita SW210-1, a 19-jewel Swiss mechanical movement that provides hours, minutes, and seconds functions. The caliber operates at 28,800 vibrations per hour and offers approximately 42 hours of power reserve, while its shock-resistant construction adds another practical advantage for a tool-oriented watch. With a stated accuracy of around ±7 seconds per day, the movement complements the SSGPM's emphasis on dependable everyday performance. Its mechanical nature also gives the watch a more traditional connection to the military timepieces that inspired the collection.

Completing the Marathon watch is a 20mm Crazy Horse leather strap in brown, which adds warmth to the otherwise monochromatic case and dial. Its distressed character works particularly well with the aged details on the dial, creating a cohesive vintage-inspired appearance. The watch is rated to 50 meters of water resistance and uses a pressure crown, making it suited to everyday wear rather than dedicated underwater use. Taken together, the asymmetric case, military-style dial, hand-wound movement, sapphire crystal, and leather strap give the Marathon Jeep Willys SSGPM Officer’s Mechanical a distinctive identity that combines Swiss watchmaking with Jeep's rugged heritage.

2. Marathon Jeep Rubicon GSAR Diver Automatic

The GSAR name refers to “Government Search and Rescue,” reflecting the model's connection to watches developed for demanding military applications. As part of the Jeep x Marathon collaboration, this reference takes that utilitarian concept into a more water-oriented design, making the Marathon Jeep Rubicon GSAR Diver Automatic particularly suited to activities that require durability both on land and underwater.

Its 41mm 316L stainless steel case has a 14mm thickness and a 48mm lug-to-lug measurement, giving the watch a solid and substantial profile. The entire case uses a satin-brushed finish that helps reduce unnecessary reflections while maintaining a clean, tool-watch appearance. A 120-click unidirectional bezel surrounds the dial, with pronounced grooves that make it easier to operate when the hands are wet. Its black anodized insert carries a 60-minute scale and a luminous triangle at 12 o'clock, providing the functionality expected from a dedicated dive watch.

The case profile reinforces its practical character with squared crown guards positioned around the textured screw-down crown. This configuration protects the crown while still allowing it to be operated when setting the watch. A screw-in case back further supports the construction's 300-meter water resistance and carries government markings alongside technical specifications. These details emphasize the model's military-oriented foundation, while the robust construction gives it the versatility to transition between outdoor activities and underwater use.

Legibility remains a major focus on the black dial. Beneath the flat sapphire crystal, Marathon combines tritium gas tubes with MaraGlo to maintain visibility in low-light environments. The hour markers and syringe-style hands use encapsulated tritium elements, while the seconds hand also carries a luminous detail at its tip. Unlike conventional lume that requires exposure to an external light source before glowing, tritium provides continuous illumination, making it particularly practical when the watch needs to remain readable in darkness. A date window sits at 4:30, while the surrounding minute rehaut includes a red-line indicator for tracking elapsed time.

This Marathon watch uses the Swiss-made Sellita SW200 automatic movement, fitted with an Incabloc® shock absorber to provide additional protection against impacts. Operating at 28,800 vibrations per hour, the 26-jewel caliber offers approximately 38 hours of power reserve and supports both hand-winding and hacking functions. Its automatic configuration also means the wearer can maintain the movement through regular wrist motion, while the hacking feature allows precise time setting. Together, these characteristics support the GSAR's emphasis on reliable performance rather than unnecessary complications.

A green three-piece rubber strap with a Marathon emblem stamped on one of its keepers rounds out the watch's rugged configuration. The color complements the military-inspired character of the dial and case while giving the model a more distinctly outdoors-oriented appearance. With its 300m water resistance, sapphire crystal, screw-down crown, unidirectional bezel, and highly visible luminous system, the Marathon Jeep Rubicon GSAR Diver Automatic stays firmly rooted in functional tool-watch design. The result is a distinctive collaboration that combines Marathon's military-oriented Swiss craftsmanship with the adventurous spirit associated with the Jeep Rubicon.

Conclusion

The Jeep x Marathon collaboration demonstrates how military heritage can shape a modern timepiece while keeping functionality at the forefront. The collection presents two different interpretations of this philosophy, with the Willys SSGPM leaning toward the classic field-watch tradition and the Rubicon GSAR taking a more rugged, dive-oriented approach. Both models carry the practical design principles that have long characterized Marathon's military-inspired watches.

The Marathon Jeep Willys SSGPM Officer’s Mechanical appeals to those who appreciate a simpler and more vintage-inspired aesthetic. Its asymmetrical case, aged-radium-style dial, and hand-wound movement give it a distinctive field-watch character, while the leather strap adds a touch of classic appeal. The 50m water resistance also makes it better suited to everyday use rather than demanding aquatic activities.

The Rubicon GSAR takes a noticeably more robust direction. Its 300m water resistance, unidirectional bezel, screw-down crown, tritium illumination, and automatic movement give it the specifications expected from a serious dive-oriented tool watch. The green rubber strap further reinforces its outdoor character, making the model feel at home in more demanding environments.

Both watches also capture the spirit of the Jeep x Marathon partnership in their own ways. The SSGPM looks to the heritage of the Willys MB and traditional military field watches, while the GSAR reflects the rugged identity of the modern Wrangler Rubicon. For collectors searching for a Marathon Jeep watch, these two models offer a clear choice between vintage field-watch appeal and contemporary dive-watch functionality, while retaining the durability and Swiss craftsmanship associated with a Marathon watch.
