If you, like me, have spent plenty of time putting together one of the best casual outfits for men, one grounded in rugged classics like the best bomber jacket and one of the best men’s henleys, for instance, then you know the importance of the little things.

The small finishing touches, like a durable field watch from the good folks at Marathon — at the top of the page, of course — can make or break an outfit, especially a casually rugged one (Think: A classic T-shirt and blue jeans, or a shawl cardigan atop a thermal henley).

When it comes to one of the best watches for men, well, if you can find a way to save some of your hard-earned cash while amping up your watch collection — and your overall #OOTD — in the process, then you’ve hit what you might call the sweet spot.

That leads us to the good folks at Windup Watch Shop, curators, designers and sellers of some of the best watches on the market from a wide array of boutique and big-name brands. Some names you very well might recognize (including big-time watchmakers like Citizen and Seiko), but the array of smaller brands — like Marathon as shown at the top of the page — is of particular interest around these parts.

And it’s the Windup Watch Shop sale section that’s of particular interest today. That’s where you’ll find one of the best field watches for men, now at a discounted price (of course — we don’t call it The Sunday Sale for nothing, my friends).

The Marathon Navigator Watch should prove particularly useful, hard-wearing and stylish, especially if it’s an underrated take on the field watch you seek, and it’s got plenty of exceptional specs to match — spend enough time at Windup Watch Shop, as you’ll see in the weeks and months ahead on this blog, and you’ll realize the brand are watch experts of the highest order.

The cleanly designed, classically inspired Marathon Navigator Watch (marked down now below $400) gets the basic specs right, from the nicely sized 41mm dial diameter to its military dial design with a 12-hour and 24-hour scale.

The ballistic nylon mil strap coordinates nicely in Black, Desert Tan or Sage Green, and the case itself is sweat and shock-resistant. Is the Marathon Navigator Watch one of the toughest field watches out there for the price? It certainly seems that way, my friends.

To hear the company tell it, Marathon watches were “designed in Canada and manufactured in Switzerland,” and were notably “designed to meet some of the toughest MIL SPEC standards out there.” Not a bad deal through a famed retailer like Windup Watch Shop, right?

And with a three-jewel battery that should last for more than five years, this timepiece will prove an “excellent grab-and-go watch for your collection.” Given the fact that it’s on sale, it’s durable as can be and it’s casually rugged enough to go with most off-duty (and adventure-minded) looks, I’d wager the Marathon Navigator Watch is the first of many Windup Watch Shop timepieces to find its way into your collection.
