Most Helpful Positive Review Looks great, runs great, wears great
The watch looks even better in person. The black IP coating is well worth it. I was concerned that it might be on the large side for my wrist but it looks great. I think that it even appears to wear a bit smaller than my SKX. The rubber strap is very comfortable (and really smells like vanilla) but I switched it out for a black Zulu with PVD hardware. The Tritium looks incredible and will make watches with standard lume look pale in comparison.

From Ruffs to Slicks this watch goes

by Dave, Verified Owner from CO, United States Written on February 1, 2025
This watch is an absolute beast. When you pick it up you can feel its weight and how solid it is. I haven’t taken it out diving yet but I intend to take it to depth as soon as the Gulf of America warms up. The GSAR is a great watch. It’s rugged and sleek enough for use at the range and classic enough to wear with dress clothes.
Pros:
  • Durability
Cons:
  • weight
Best Used for:
  • Range
  • field
  • business
  • scuba
Would recommend: Yes

amazing watch

by luke2-2008, Verified Owner from KY, United States Written on January 2, 2025
This is an amazing watch. It is built like a tank, I highly recommend it and the steel bracelet. You can go from a nice everyday watch to a nice dress watch.

Marathon GSAR 41mm

by LDL, Verified Owner from CA, United States Written on July 21, 2024
Good looking watch, great for daily wear (of course it's engineered for more extreme conditions). Optics Planet had the lowest price and they are an authorized dealer for Marathon so you get the 2 year warranty (you get an additional year warranty when you register online with marathon). The tritium inserts are great at night. Swiss made with automatic movement. The history of the company.
Pros:
  • good quality
  • Aesthetics
  • no batteries
  • Tritium for night time
Cons:
  • Expensive maintenance every 5-7 years
Best Used for:
  • Whatever you want, it's build like a tank
Would recommend: Yes

Heavy duty watch but functional and refined!

by supernachos, from CA, United States Written on April 5, 2023
First of all I want to say that visually, this watch takes me where I want to go! It is heavy duty and the look is Teutonic. I replaced the rubber strap with a aftermarket StrapCode stainless steel Super Engineer band and the looks is killer!

Cons:
This watch is super heavy on your wrist and after some time wearing it (in days) you may experience some wrist pain like I do. I simply rotate alternately wearing it on my other wrist.

I also had to return my watch to Service under warranty to Canada. I think I manually over-winded the mechanism and a spring internally snapped but it was covered under warranty. The warranty service was a straightforward process, mailing it to their Support in New York. They then ship it to Canada for actual repair. It took about a month to get back to me but I think the service actually improved the watch mechanism and I'm glad I sent it in!
Pros:
  • Beautiful and functional
Cons:
  • Heavy
  • heavy and thick
Best Used for:
  • everyday use
Would recommend: Yes

Always on my wrist

by Benji, Verified Owner from FL, United States Written on March 18, 2023
I was looking for a tough as nails almost indestructible watch and this one checks every box. I wasn’t a huge watch collector prior to purchase the GSAR, That’s said I knew about Marathon and their historic ties to the military. So far I have worn it for the last few months and I have nothing but great things to say about it.
Pros:
  • Swiss-quality tritium
  • swiss movement
Cons:
  • price (but it's worth it if you need reliability and quality)
Best Used for:
  • every day and low light
Would recommend: Yes

This watch is an animal

by Justin Smith, Verified Owner from AL, United States Written on January 17, 2023
Long story short I’ve owned this watch for roughly just over a year and have worn it daily. I’ve worked in construction grinding and pounding away, Heavy Equipment operating and maintenance. If you know anything about maintenance on heavy equipment it’s a lot of brute force when maintaining them lol. Need less to say whether this watch was rated for all that beating or not, I don’t baby my watches and the GSAR has purred through it all. I love the Tritium as well. Dial is Easily legible in all environments and just glows at night. Everyone loves the look of this watch and it wears great. I’m looking at buying the Arctic version as well because I’m so impressed with this watch
Pros:
  • Looks great
  • tough
  • Tritium
Cons:
  • None
Best Used for:
  • Anything & everything

U.S. MARINES GSR Automatic

by dsizzle, from CA, United States Written on January 16, 2021
I was a little skeptical at first because of the sheer size and heft of this watch. My experience with the fit and finish of government contracted/issued watches and gear is spotty at best. I also thought having the U.S. Government stamp on the face of the GSAR was part of the cache. However, this watch is amazingly comfortable for its size. The large knurled screw-down crown does not even dig into the back of my hand when doing push-ups! The bezel is not sharp or obtrusive and audibly clicks off in 30 second increments for precise dive time monitoring in limited visibility. The soft vulcanized rubber strap gives off a faint “plain vanilla” essence which, rather than being less manly, is strangely quite appropriate for such a “Spartan” watch. As a result, the strap doesn’t constantly reek of sweat and grime like my hard rubber G-Shock and it doesn’t cut into my skin. This watch has covert “wow factor” because it uses the same Swiss-made automatic 25 jewel movement as many of the top and much more expensive designer watches. I am a Casio G-Shock Tough Solar fan, but on my last deployment, I struggled to keep it fully charged due to working at night and with sleeves down. Automatic movements may loose a few more seconds than a quartz over a month’s time, but if you wear it daily and synchronize weekly, you have an amazingly accurate perpetual motion machine with 48 hours of stored reserve power and no batteries! In addition, the Tritium gas tubes give off the perfect amount of ...

US Marines GSAR

by dsizzle, from CA, United States Written on January 16, 2021
This watch is rather Spartan, which is a good thing. It has the chiseled rugged good looks of the Government SAR with the added benefit of official USMC religious cult markings. The vulcanized rubber strap is comfortable. The strap also really smells like vanilla, which is better than the essence of sweat from my G-Shock and is rather fitting for such a “no-frills” utility watch. I also purchased the stainless Marine EGA band, which is easy to swap out to dress it up some. The rotating bezel has audible clicks at 30-second increments for dive time accuracy in poor water visibility. The Tritium gas lume is great and reminds me of the old lensatic compasses we were issued back in the day before they changed to the Phosphorescent models. The bottom line is that this is a solid watch that is comfortable to wear. This is the same dependable automatic mechanism used in other Swiss-made watches, but at a more affordable price-point.
Pros:
  • Utilitarian. Official licensing benefits Marine Corps programs.
Cons:
  • None
Best Used for:
  • Daily wear, diving. water sports
Would recommend: Yes

Gold standard for tool watch; insane dial depth

by r3ing, from MD, United States Written on September 21, 2020
Insanely well built. The depth of the dial simply cannot be captured in pictures. The dial being so deep and actually smaller in diameter makes the watch wear smaller than the size would otherwise indicate. I have a 6 3/4 inch wrist and it is sturdy, but totally works. Not for everyone, but perfect for me.
