All about the MARATHON 41mm Duvdevan Desert Tan Pilot Navigator – WW194013DT
Military DNA – Reimagined
The new version of the Marathon Steel Navigator draws on a legendary chapter in military watch history. Originally, this model was developed in 1986 in close collaboration with the Kelly Air Force Base – a timepiece that then, as now, stands for uncompromising functionality and absolute reliability. This revised version stays true to the original concept, but combines classic design with modern technology and lightweight, durable materials. It is a true tool watch, designed for professional use and built to military standards.
Swiss Precision at its Heart
Inside the watch, a powerful quartz movement, entirely manufactured in Switzerland, is at work. The integrated ETA F06.115 HeavyDrive not only guarantees maximum accuracy but is also known for its shock resistance – a must in military environments. Equipped with three jewels, this movement provides stable and precise timekeeping. The date display is also subtly yet functionally integrated into the dial.
Light, Durable, Functional
The case consists of a high-impact composite fiber shell, which is both lightweight and extremely robust. Its special composition reliably protects the watch from mechanical impacts – a clear tribute to the principle of military operational readiness. The pressure-sealed crown and scratch-resistant sapphire crystal perfectly complete the protection concept. The watch is water-resistant up to 6 ATM, making it ideal for everyday use and outdoor activities.
Clear Readability Day and Night
The deep black dial features easily readable 12-hour and 24-hour scales. The hour markers as well as the hour and minute hands are equipped with self-illuminating tritium tubes – a feature that guarantees continuous readability in complete darkness without the need for an external light source. This technology significantly distinguishes the watch from conventional luminous materials and underlines the professional claim of this model.

Versatile and Combinable with Practical Straps
For maximum flexibility, various strap options are available. Whether a ballistic nylon strap, a classic DEFSTAN nylon strap, or a 316L stainless steel pin buckle – every element is designed for durability, wearing comfort, and everyday suitability. The width of 20 mm ensures harmonious proportions on the wrist and emphasizes the watch's functional look.
A Manufacturer with Tradition and Responsibility
Since 1941, Marathon has manufactured timekeeping instruments for the Allied Forces. Today, the fourth generation continues this legacy, offering a wide range of products, including watches and devices for measuring temperature and distance. Military robustness meets fine Swiss watchmaking artistry. Marathon remains a reliable supplier to the active military – a testament to the uncompromising quality promise that still holds true today.
Quality You Can Rely On
Each watch is manufactured with the utmost care and undergoes strict quality controls. The company places importance not only on technical perfection but also on first-class customer service. Marathon stands not just for timekeeping but for trust, reliability, and decades of experience – a combination proven not only on the battlefield but also in everyday life.

FAQs
About David from WATCHDAVID
Behind WATCHDAVID.SHOP, I, David Drilling, stand as a true watch enthusiast, watch photographer, and independent tester. Since 2018, I have been providing honest wear reports on my channels. In my shop, I exclusively sell watches whose quality and history I have personally verified. No anonymous mass-produced goods, but personal expertise.
Shipping & No Import Charges
Shipping within Germany and the EU is completely free for you and fully insured via DHL or FedEx Express. Important for you: There are guaranteed to be no import duties, taxes or hidden fees. The exact delivery time for your model will always be transparently displayed directly above the "Buy" button.
Cancellations & Free Returns
You can easily cancel your purchase within 14 days. Unlike other retailers, I will cover the full cost of your return shipping within the EU. Simply send me a short email to david@watchdavid.com and I will send you your free DHL return label. It doesn't get any more risk-free than that.
Authenticity & Condition of the Watches
I guarantee you 100% that all watches offered are unworn, brand new original goods. In the shop, I strictly differentiate between regular new goods directly from the manufacturer and exclusive photo watches. Photo watches are models that I have used for my videos or photos, or that come from a return. I sell them absolutely honestly as used and significantly reduced – but the full manufacturer's warranty only begins on the day of your purchase!
Warranty & David's "All-Round Carefree Service"
Every watch comes with the full, international manufacturer's warranty (at least 2 years). In the event of a warranty claim, you'll have absolutely no stress: I'll handle all communication with the brand and organize insured round-trip shipping for you. Even after the warranty period expires, I remain your personal point of contact for service inquiries.
Quality Control
Mechanical watches are fascinating masterpieces. Before dispatch, each watch undergoes a thorough optical and mechanical final inspection. Should a problem ever arise despite our secure transport protection, please inform me immediately by email. I will promptly arrange for a quick, uncomplicated replacement.
