MARATHON Blue Yonder SSNAV-D Steel Navigator Quartz WW194013SS
All about the MARATHON Blue Yonder SSNAV-D Steel Navigator Quartz WW194013SS
Precision and resilience for extreme missions
The latest version of the classic GSAR Quartz from Marathon is a true tool for professional use – designed for search and rescue missions under the toughest conditions. Inside operates a high-torque quartz movement, manufactured in Switzerland, offering the highest reliability. The proven caliber ETA F06.115 HeavyDrive powers it, featuring not only an EOL indicator (End-of-Life) but also impressing with its robustness. It has three jewels and can easily compensate for mechanical stresses such as shocks or vibrations – a must for professional applications.
Military-grade case construction
The watch case is made of high-quality, brushed 316L stainless steel – a material valued not only for its corrosion resistance but also for its comfortable feel on the skin. With a diameter of 36 mm, a height of 14 mm, and a lug length of 43.5 mm, the case offers a compact yet extremely durable design. The timepiece is water-resistant up to 300 meters (30 ATM), making it perfectly suitable for underwater use. The screw-down crown further enhances the pressure resistance and ensures maximum watertightness underwater.
Maximum functionality in any light
The unidirectional 60-minute bezel can be precisely adjusted with 120 clicks and is equipped with a MaraGlo-illuminated marker. This luminescent marking guarantees optimal readability even in complete darkness – ideal for operations at night or underwater. The scratch-resistant sapphire crystal reliably protects the dial from mechanical influences and preserves readability in the long term.
Clear readability at a glance
The matte dial is deliberately kept simple while offering maximum clarity. In addition to the classic 12-hour scale, a second 24-hour display is integrated, making the watch suitable for military time indications. The indices as well as the hour, minute, and second hands are equipped with self-illuminating tritium tubes – a durable, self-luminous material that remains visible permanently without an external light source. Additionally, the date display at 4:30 o'clock is discreetly integrated without disturbing the layout.
Two strap options for individual operational requirements
Depending on personal preference or application, two high-quality strap variants are available: A durable, black rubber strap with stainless steel pin buckle or a solid stainless steel bracelet with secure folding clasp. Both straps were specially developed for extreme stress and offer optimal wearing comfort as well as high functionality.

FAQs
About me
My name is David, I was born in the late 60s in NRW, now live and work in the beautiful Harz Mountains, and have been running this watch shop, among other things, since spring 2022.
Since 2018, I have also been running my watch blog watchdavid.de, which features hundreds of reviews and watch news. Since then, I have taken thousands of professional watch photos for over 100 watch brands. Many photos can be found in my reviews. I am known worldwide for this.
As a result, I naturally had thousands of watches in my hands. And with this shop, I want to bring you closer to watches that have convinced me in many ways.
So come along on a journey full of watches... off the mainstream... and if you have a question, please feel free to ask me anytime via the form, chat, WhatsApp, email or phone.
I am very much looking forward to meeting you.
PS: My hobbies & passions include the internet (first agency already in 1996), Denmark, France's coasts (Brittany, Normandy & Côte d’Azur), hiking, e-MTB, sales (Bachelor of Sales) and photography.
My Achilles' heel includes children's chocolate, good food, sneakers & of course watches... :-)
Shipping & Insurance
Within Germany and the EU, I ship free of charge. Shipping is done via DHL and insured up to 500€, 2,500€, or 25,000€, depending on the watch value. The watches are thus always sufficiently insured.
The delivery time can be found in the description and/or under the shopping cart button. Some watches are only produced after ordering, others are brand new and, for example, only available in a few weeks (so-called PRE-SALE), etc...
Cancellation & Return Shipping
You can cancel your purchase within 14 days of receiving the goods.
I will cover the costs for the return shipping for you.
IMPORTANT: Do not send the watch back yourself, I will send you the free return label.
Please simply contact me for this. david@watchdavid.com
It is also important that the watch is unworn and free of signs of use. After successful inspection, I will refund you the purchase price. The refund will be made using the same payment method you used for the purchase.
Authenticity & Condition of the Watches
I guarantee you that all watches I offer are exclusively new original products. The watches come directly from the manufacturer and have had no previous owners, unless I explicitly point this out (e.g. so-called PHOTO WATCHES).
As an official dealer, I offer you exclusively authentic products. These are offered in the original packaging, with warranty card, etc., just as they are delivered by the dealer. Everything in the so-called full set. One delivers more, another less...
Warranty & Service
All watches purchased from me come with the international manufacturer's warranty, which usually lasts two years. Some brands even offer a warranty of up to 5 years.
If a warranty case occurs, I will take care of the shipping to the manufacturer or the responsible service center for you and also organize the return shipment to you. In addition, I handle all communication with the manufacturer so that you don't have to worry about anything.
Even after the warranty period has expired, I remain your contact person and support you with service questions or repairs.
No response received?
You wrote to me via the contact form, through the price proposal, directly by email, chat, but you haven't received a reply?
Then please check your SPAM folder! Many providers are getting crazier and pushing more and more into spam.
I usually answer every inquiry within 24 hours at the latest. On weekends, it can sometimes take a bit longer. As a rule, I respond within a few minutes or hours.
Something can slip past me sometimes too. Or the technology doesn't work as it should. Feel free to write to me again at david@watchdavid.com
Mechanics - Sometimes things can happen there too
Before I ship your order, I carefully check each watch for visible defects.
If a problem should occur, such as damage during transport, please inform me immediately. I will do everything possible to quickly find a solution and ensure that you are satisfied.
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!
