MARATHON SSNAV Steel Navigator Quartz Black Dial WW194001SS

Modernized field watch with military origins

The newly interpreted Steel Navigator from Marathon is not just a classic tool watch, but a full-fledged operational instrument. Its origin dates back to 1986, when the original model was developed in cooperation with Kelly Air Force Base specifically for US Air Force pilots. The new edition remains true to this mission, but has been revised for civilian and professional everyday use and technically brought up to date.

Precise quartz movement for maximum reliability

Inside, the Swiss quartz caliber ETA F06.412 operates, equipped with HeavyDrive and PreciDrive technologies. The movement impresses with exceptional shock resistance and particularly high accuracy. Three jewels ensure durable and low-friction function – exactly what you expect from a watch with military demands.

Extremely robust case with corrosion protection

The case is made of 316L stainless steel, which has been refined by so-called Parkerization – a phosphate conversion coating. This surface treatment reliably protects the watch against corrosion and at the same time gives it a matte, reflection-free appearance. With 10 ATM water resistance, a screw-down crown, and scratch-resistant sapphire crystal, the watch is built for harsh conditions.

Perfect legibility – day and night

The matte black dial features a 24-hour display in addition to the 12-hour scale. Particularly striking are the indices and hands equipped with tritium gas light sources – a technology that glows continuously without external light. This permanent self-illumination makes the watch ideal for use in complete darkness. All three hands – hour, minute, and second – are also equipped with tritium tubes.

Well-thought-out functions for operational use

In addition to reliable time display, the watch offers a bidirectionally rotating bezel, which allows flexible time measurement – for navigation or coordination purposes, for example. The dimensions of the watch have been chosen so that it remains comfortable despite its robust appearance: 41 mm diameter, 11 mm height, and 48 mm lug-to-lug result in a sporty-compact presence on the wrist. With a 20 mm lug width, a wide variety of straps can be easily combined.

Flexibility through various strap options

A wide selection of high-quality straps ensures individual customization. Marathon offers, among others, a ballistic nylon strap, a particularly robust DEFSTAN nylon strap, and a three-piece rubber strap kit. The ensemble is rounded off by a stainless steel pin buckle with black IP coating, which perfectly complements the functional character of the model.

Tradition and quality since 1941

Marathon looks back on a long history: Since 1941, the family business has been producing timepieces for Allied forces. Today, the company is still run by the fourth generation and continues to supply active military units worldwide. Marathon stands for a successful combination of military robustness and Swiss precision.

Controlled manufacturing and first-class support

Every Steel Navigator is created with great care and undergoes a series of strict quality checks. Marathon places great emphasis on workmanship quality and supports its customers with reliable support, which ensures trust and long-term satisfaction. Those who wear this watch not only carry a piece of history, but also a tool made for the highest demands.
