All about the 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.

FAQs
About David from WATCHDAVID
My name is David, and I've been deeply involved with watches for many years – not just as a dealer, but primarily as a tester, photographer, and classifier.
Since 2018, I’ve been running WATCHDAVID as an independent watch project featuring reviews, videos, and real-world wearing experiences. Many of the watches you'll find here have been on my own wrist – often for extended periods.
WATCHDAVID.SHOP is intentionally personal. I only sell watches that I genuinely stand behind – no anonymous mass-produced goods, no dropshipping, no "quick trends." Experience, transparency, and honest assessment are paramount to me.
And yes: I am not an anonymous seller. I enjoy good food, sneakers, and photography – and I have a proven weakness for Kinder Chocolate.
If you have any questions or are unsure, feel free to contact me directly. I will respond personally.
Shipping & Insurance
Within Germany and the EU, shipping is free of charge. Shipping is handled by DHL and insured up to €500, €2,500 or €25,000, depending on the watch's value. The watches are therefore always sufficiently insured.
You can find the delivery time in the description and/or below the shopping cart button. Some watches are only produced after an order is placed, while others are brand new and, for example, will only be available in a few weeks (so-called PRE-SALE), etc...
Revocation & Return Shipping
You can revoke your purchase within 14 days of receiving the goods.
I will cover the return shipping costs for you.
IMPORTANT: Do not send the watch back yourself; I will send you the free return label.
To do this, please simply contact me. david@watchdavid.com
It is also important that the watch is unworn and free of any signs of wear. After a successful inspection, I will refund the purchase price to you. The refund will be made using the same payment method you used for the purchase.
Authenticity & Condition of the Watches
I guarantee that all watches I offer are exclusively new, original goods. The watches come directly from the manufacturer and have had no previous owners, unless I explicitly state otherwise (e.g., so-called PHOTO WATCHES).
As an official dealer, I exclusively offer authentic products. These are offered in their original packaging, with a warranty card, etc., just as they are delivered by the dealer. Everything in a so-called Full Set. Some deliver more, some less...
Warranty & Service
All watches purchased from me come with the international manufacturer's warranty, which is usually two years. Some brands even offer a warranty of up to 5 years.
Should a warranty claim arise, I will take care of shipping the watch to the manufacturer or the responsible service center for you and will also organize its return to you. In addition, I will handle all communication with the manufacturer, so you don't have to worry about anything.
Even after the warranty period has expired, I will remain your contact person and support you with service questions or repairs.
No answer received?
You contacted me, via the contact form, about the price proposal, directly by email, chat, but you didn't receive a reply?
Then please check your SPAM folder! Many providers are getting crazier and crazier and are sending more and more to spam.
I usually answer every inquiry within 24 hours at the latest. On weekends, it may take a little longer. As a rule, I reply within a few minutes or hours.
Something can also slip through for me. Or the technology isn't working as it should. Feel free to contact me again. david@watchdavid.com
Mechanics - Sometimes things can go wrong
Before I ship your order, I carefully inspect each watch for visible defects.
However, should a problem arise, such as a defect during transit, please inform me immediately. I will do everything in my power to find a quick solution and ensure your satisfaction.
My goal is to offer you not only high-quality products but also a first-class shopping experience. I look forward to welcoming you as a satisfied customer!
