Unique actual USMC Military issue mechanical sell-winding diving watch...features "USMC" logo printed on dial and deep laser engraved on side!  Brand new, with laser engraved latest contract date and individual serial numbered back.  This is similar to the famous discontinued SAR model except the dial utilizes the revolutionary tritium glass vial illumination system.  It is rated for 1000 foot submersion.  It is a nice sized watch.  The movement is a 25 jewel automatic ETA 2824-A2 that has been adjusted for positions and temperature.  The crystal is sapphire - 2.8mm thick x 30.50mm diameter.  The case is cut from solid 316L stainless steel and is approximately 41x46mm in diameter.  The unidirectional bezel diameter is 41.10mm and case height is 13.85mm.  The steel back has full military markings.  Screw down crown is deep knurled.  The total weight of the watch head is 93.1 grams. Supplied with black Swiss made 20mm military natural rubber strap.

This GSAR features an ETA 2824-A2 engraved with Marathon Watch Co. and an improved 120 click uni-directional rotating bezel.  Check out the photos of this watch next to a Rolex Submariner for size comparison (Rolex Sub. not included).  There are limited number of these watches available. 


The GSAR is considered by many to be the ultimate current issue military watch and a superb dive watch!   

This is new in government box (new style box) with instructions.  It comes complete with black natural rubber strap with two keepers with Marathon logo on one.  

There is a 30 day return privilege if not properly described.  

This watch is covered by a full 2-year manufacturer's warranty because you are purchasing it from an authorized Marathon Watch Co. agent.      

This watch will be shipped from the USA. 

Makes a great gift too!

Don't settle for imitations or rejected material. Why not own an original, first quality, authentic, current military issue watch?

I have been collecting military watches for over 25 years and am a member of the National Association of Watch and Clock Collectors (NAWCC).  Many collectors over the years have been pleased with my recommendations for future collectible watches......this is one model I am currently recommending. 

Please feel free to contact me with any questions about this watch including shipping cost to destinations outside the US.  I am always happy to discuss other military timepieces and Marathon watches as well.  

Feel free to check out my other items too!

NOTE:  I also have this watch with sterile (non-US Gov. marked dial) or US Government signed dial.
