All about the MARATHON 41mm STEEL NAVIGATOR DATE (SSNAV-D) WW194013SS-0101
Reinterpretation of the Steel Navigator
The Steel Navigator with Date (SSNAV-D) represents a completely redesigned evolution of the original Marathon Steel Navigator, which was first conceived in 1986 in collaboration with Kelly Air Force Base. This watch was specifically designed for pilots, paratroopers, and adventurers, and it impresses with a combination of robust construction and high precision. With a diameter of 41 mm, the SSNAV-D presents itself as a reliable companion, offering remarkable accuracy of ± 10 seconds per year thanks to its ETA F06.412 HeavyDrive-PreciDrive quartz movement – a milestone in the history of the Steel Navigator series. Particularly noteworthy is the date display, a first for this model since the original design in the 1980s.
Robust Case and Ergonomic Design
The SSNAV-D's case is made of high-quality 316L surgical stainless steel, which not only provides an appealing look but also the necessary robustness. The watch is equipped with a screw-down crown, which, together with the synthetic sapphire crystal, ensures water resistance up to 10 ATM (equivalent to 100 meters depth). This makes the Steel Navigator ideally suited for diving or wet conditions. The case design has been modernized and features a tapered bezel that is ergonomically shaped, guaranteeing a comfortable fit on the wrist – an important advantage for daily use.
Practical Bezel Functions
A particularly practical feature of the bezel is its 12-hour GMT function, whose raised height provides a better grip. This allows it to be rotated effortlessly in both directions, even when pilots are wearing thick flight gloves. The inlaid, painted indices on the bezel also significantly improve the readability of the markings, making operation easier under all conditions.
Optimal Visibility in Darkness
Self-illuminating Tritium gas tubes, applied to all hour markers and to the hour and minute hands, ensure optimal visibility in dark or poorly lit environments. Unlike conventional photoluminescent paint, tritium tubes do not fade over time, as they contain a hydrogen isotope that constantly emits light. This ensures the watch remains perfectly legible at all times of day and night.
Crystal Clear and Pressure Resistant
The dial is protected by a scratch-resistant sapphire crystal, which not only provides clear visibility but also withstands extreme changes in air pressure – an essential feature for pilots operating at altitudes above 5,000 feet. The combination of Swiss manufacturing and Canadian design guarantees the highest quality and meticulous workmanship that meets the demands of professional users.

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!
