MARATHON Blue Yonder SSNAV-D Steel Navigator Quartz WW194013SS

Tradition meets tactical precision

Since the year 1941, the brands Jeep and Marathon have shared a common history that goes far beyond mere design. Originally connected through the military supply of the Allied forces, both companies developed tools and equipment over decades that soldiers worldwide could rely on. This close cooperation today finds a stylish and highly functional continuation in the Jeep x Marathon collection – a tribute to shared values such as reliability and readiness.

Swiss technology with high-torque performance

At the heart of this robust mission watch beats a Swiss-made quartz movement of the latest generation. It comes from the renowned manufacturer ETA SA in Grenchen and carries the caliber designation F06.412 HeavyDrive. This caliber line is known for its durability, resilience, and precise accuracy. The HeavyDrive technology not only delivers particularly high torque – for example, for heavy or luminescent hands – but also actively protects the movement against shocks and magnetic fields. The whole is complemented by an integrated end-of-life indicator (EOL), which signals early when a battery change is due – a detail that is both practical and safety-relevant.

A case built for extreme conditions

Made from solid, brushed 316L stainless steel, the case of this watch stands for uncompromising robustness. With water resistance up to 30 ATM (300 meters), it meets professional requirements – whether diving, in harsh terrain, or in the everyday life of emergency personnel. The unidirectional 60-minute bezel features 120 defined clicks for precise time measurement and is equipped with MaraGlo® – a luminous material that reliably marks the zero point even in complete darkness. The equipment is rounded off by a screw-down crown and an extra-thick, scratch-resistant sapphire crystal, which ensures perfect readability even under the toughest conditions.

Dial with tactical clarity

The deep black dial is deliberately designed to be functional and features a clear 1–12-hour scale for quick overview. The date display at 4:30 is discreetly integrated yet easily readable. Particularly noteworthy are the self-illuminating tritium tubes on all indices as well as on the hour, minute, and second hands – a technology that glows constantly without an external light source, thus guaranteeing absolute readability over many years. For operational missions in darkness or underwater, this is a decisive advantage over conventional luminous paints.

Two straps – ready for any mission

When choosing the strap, this watch offers maximum adaptability. It is delivered optionally with a black or olive green rubber strap from Marathon, each with a solid stainless steel pin buckle. These straps are specially designed for professional use – resistant to saltwater, UV radiation, and chemical influences. They provide not only comfort but also safety – whether in urban everyday life or on tactical missions.

A tool for life – and far beyond

With the Jeep x Marathon Quartz, more than just a watch is created. It is an expression of technical sovereignty, military testing, and decades of collaboration between two brands known worldwide for reliability and strength. In every screw, every material, and every design decision, there is a clear message: This watch is made for people who know no compromises – neither in style nor in performance.
