Marathon 41MM Steel Navigator Date

The Marathon 41MM Steel Navigator w/ Date Automatic (SSNAV-D AUTO) is a watch that has been generating a lot of buzz lately, and for good reason. This new timepiece from Marathon Watch Company is a modern take on the brand's classic pilot's watch, the Steel Navigator, which was first introduced in 1986. The SSNAV-D AUTO builds upon the legacy of the original Steel Navigator while adding a number of new features and upgrades that make it an even more compelling option for pilots, military personnel, and everyday watch enthusiasts alike.

Founded in 1939, Marathon Watch Company is a Canadian company that has a long history of producing high-quality, reliable watches for the military and government sectors. The company's watches are known for their durability, functionality, and precision, and they have been used by military personnel around the world for decades.



The original Steel Navigator was developed in partnership with Kelly Air Force Base in the United States, and it quickly became a favorite among pilots for its legible dial, rugged construction, and reliable performance. The SSNAV-D AUTO stays true to the original design while incorporating modern materials and technology to create an even better watch.

From a quick glance at the watch, it's clear that the SSNAV-D AUTO is built to withstand anything you throw at it. The watch features a 41mm stainless steel case that is treated with a parkerized finish for enhanced corrosion resistance. The case is also water-resistant up to 10 ATM (100 meters), making it suitable for swimming and diving.

One of the most notable features of the SSNAV-D AUTO is its 12-hour bezel. The bezel is bi-directional, which means it can be rotated in either direction. This allows pilots to easily track elapsed time, which is essential for tasks such as navigation and timing maneuvers. The bezel also features inset-painted indices that are easy to read, even in low-light conditions.

The dial of the SSNAV-D AUTO is black and features large, easy-to-read Arabic numerals and hour markers. The hands are also coated with tritium gas tubes, which means they will glow in the dark without needing to be exposed to light. This makes the watch easy to read in any lighting condition, which is essential for pilots who may need to check the time in the cockpit at night.

Another new feature of the SSNAV-D AUTO is the date window at the 4:30 position. This is a welcome addition for those who want a watch that can be used for everyday wear as well as for professional use.



The SSNAV-D AUTO is powered by a Sellita SW200-1 automatic movement. This is a Swiss-made movement that is known for its reliability and accuracy. The movement has 26 jewels and a power reserve of 38 hours.

The Marathon 41MM Steel Navigator w/ Date Automatic is a watch that is built to last. It is a well-made, reliable timepiece that can be used for a variety of purposes. Whether you are a pilot, a military professional, or simply someone who is looking for a durable and functional watch, the SSNAV-D AUTO is a great option to consider.

Let's be honest, the movement is where the rubber hits the road for any respectable watch. Marathon went with a solid choice here: the Sellita SW200-1 automatic. It's a robust little workhorse with 26 jewels, renowned for its dependability. One neat bit about the movement is the addition of an Incabloc® Shock Absorber. Essentially, it gives that extra bit of protection against hard knocks and vibration – a welcome addition considering this watch's intended audience.



Marathon didn't mess around with the SSNAV-D Auto's dial. It's focused, legible, and straight to the point. The matte black face contrasts beautifully with the crisp white Arabic numerals. It's not just about looks, though. The hands and hour markers are filled with those awesome tritium gas tubes Marathon is known for. Remember, they glow constantly without needing to be "charged" by sunlight – a major boon for those night flights.

Some might feel the date window at 4:30 throws off the balance a bit. It's not a deal-breaker, but considering the original Navigator's sterile dial, it does change the aesthetic slightly. That said, it offers extra day-to-day practicality, which is always a win.

This bad boy is housed in 316L surgical-grade stainless steel. It ain't your grandpa's shiny dress watch steel. This stuff is the toughest of the tough, often used for marine applications due to its corrosion resistance. The whole case sports a parkerized finish – a kind of matte, gunmetal gray that eliminates glare, perfect for tactical situations where a flash of reflected light could be a problem.



Protecting that no-nonsense dial is a sapphire crystal. Ask any watch enthusiast and they'll wax poetic about how sapphire is the king of watch crystals – virtually scratchproof and able to withstand some serious pressure changes. For a pilot shooting up to 35,000 ft, that resilience is key.

Getting a precise set on a watch is satisfying. The SSNAV-D AUTO gets the basics right with a sturdy, screw-down crown. You get that extra seal against water and dust, and it just feels tougher when you're cranking it down.

Now, let's talk about the star of the show - that bi-directional bezel. It's a beefy thing, noticeably taller than previous versions of the Navigator, intentionally designed for better grip, even when wearing thick flight gloves. The markings are inset and painted for a clean, legible look. It's smooth yet firm to turn... that satisfying mechanical feeling that lets you know you're working with a quality piece.

Marathon tosses in a neat little bonus with the SSNAV-D AUTO: a premium FKM Rubber 3-Piece Strap Kit. FKM is the good stuff, known for crazy durability and resistance to all sorts of chemicals. And this kit's no slouch in the engineering department – it's manufactured in Switzerland with specific military requirements in mind.



The three-piece system is clever. You get two different length buckle parts, letting you fine-tune the strap for the perfect fit with minimal excess. Think less bulky, more comfortable, and streamlined on the wrist.

The Marathon 41MM Steel Navigator w/ Date Automatic is a purpose-built machine. It doesn't try to be flashy or win design awards. What it does, it does well. It's a reliable tool crafted for the rigors of aviation, infused with Marathon's military watchmaking DNA, now with the convenience of an automatic movement.
