Marathon Swiss Made, (Medium) GSAR Automatic Military Divers Watch with Sapphire Crystal #WW194026

The Marathon Diver’s Automatic Medium is a dive watch built to ISO 6425 standards but is a smaller, medium sized, version of Marathon’s line of diver’s watches, perfect for someone who wants a tough, reliable, and military issue dive watch, yet prefers a reduced size watch that is just as tough as its larger brothers.

The Diver’s Automatic Medium is a dive watch certified for water resistance down to 30 ATM - 300 meters (1000 feet) underwater. The Diver’s Automatic Medium uses a scratch resistant sapphire glass crystal to ensure it maintains maximum legibility. Built from 316L surgical grade stainless steel, the Diver’s Automatic Medium is a tough watch that is comfortable for people with smaller wrists.

The Diver’s Automatic Medium includes a vulcanized rubber strap. When first worn, the strap will have no holes to put the buckle through and instead must be carefully pierced. This can be done to create a custom fit for superior comfort.

The Diver’s Automatic Medium is made in La Chaux de Fonds Switzerland to guarantee the highest level of quality and accuracy in manufacturing. Inside the Diver’s Automatic is a Swiss made, Marathon M2, 26 jewel Sellita SW200 automatic movement which gives you a reliable and accurate timekeeping experience. The Diver’s Automatic Medium uses self contained Tritium gas tubes to ensure constant visibility in low light situations, a gas tube is placed on each hour marker and hands and uses MaraGlo for the 12 hour bezel marker. Tritium tubes are self illuminating gas tubes which contain an isotope of hydrogen, meaning they will not dull down in brightness like normal photoluminescent paint which requires an external light source to create a glow.

The Diver’s Automatic Medium boasts the same toughness, water resistance, and movement as the larger Marathon diver’s watches in a compact package. To maintain proper tracking for maintenance, each Diver’s Automatic Medium comes individually numbered and engraved with a serial number.

    Marathon MSAR

    Posted by Patrick on Jun 9th 2021

    I bought this watch to replace my SEIKO SKX as my do it all beater watch. I am in the military and wanted it to be able to hold up in that environment. It has done that and more. I am also very pleased with the 36mm size. I have 6 3/4 inch wrists and it's the perfect size for wrists up to 7 inch wrists. Anything larger and I'd recommend the GSAR. The purchase process from Mark and LIW was seamless and I was able to get additional discounts because this was my first purchase from the site. Thanks Mark. I'll be back.

    Fantastic watch that wears great. It seemed really diminutive before I put it on but on my wrist it’s basically perfect. Chunky enough to have some presence while still looking balanced. The tritium is super cool too.

    Marathon Midsize GSAR Rocks

    Posted by Luis Figueroa on Feb 24th 2020

    I just purchased the midsized Marathon GSAR from Long Island Watches and have been wearing for about a week. It’s a great looking watch that wears well, especially on a smaller wrist. It’s running about 3-4 seconds fast per day. The strap feels soft and has a nice bouquet. It’s quickly becoming one of my favorite watches. As far as Long Island Watches you can’t beat their price and service!

    One month with Marathon GSAR medium/auto

    Posted by Ken H in MI on Oct 3rd 2019

    One month in and very satisfied with purchase. As often mentioned in reviews it come across as small out of of the box but on my 6.75" wrist it has perfect scale and presence. Overall workmanship/detail quality is in keeping with price and usage. The tritium brightness/legibility at night is awesome. If you've seen video reviews and worried about brightness feat not. The tritium is truly a major strength of the watch. For time keeping, first week watch was about 2 seconds a day slow but since second week gradually fell to current 9 seconds a day slow where it has held for past 2 weeks.

    I’d been looking at the marathon GSAR watches for some time, they are a well built, accurate time piece, but I felt that the 41- 46mm size was more watch than I’d be comfortable wearing. When they came out with the same watch scaled down to 36mm and with an automatic movement I was thrilled. I’ve been wearing the watch on a daily basis for a month now and couldn’t be happier. The service from Long Island watch was excellent. On time and exactly as advertised. Also I found the video reviews to be very helpful, especially the video comparing the three sizes of the marathon GSAR watches.
