This is the classic Marathon GSAR with the USMC branding. GSAR, being Government Search And Rescue. I have the Marathon GSAR and love it. IMHO, it is one of the best watches ever made.

I got this one for a family member that is a Marine. It's no frills with the rubber strap, and looks as good if not better than a Rolex Submariner when on the SS bracelet. On the stainless bracelet, this can be you one watch does all. I wear mine at the gym, work, and wear it out to dinner. I have a Rolex, Tag, and a few other fancy watches, and this Marathon is getting most of my wrist time now days. It is built mil-spec, and even feels like it.

It is an automatic, so for those of you not familiar... This means you have to keep it wound, or it will stop running. As an automatic, just wearing it keeps it wound. It keeps great time. The price is fair for a good quality Swiss automatic movement. If I could only have one watch, this GSAR would be it. The pictures do not do this watch justice. Get one of these.

FOLLOW THE DIRECTIONS on how to care for this watch, and it will last you many years. As with most dive watches, it has a screw down crown. As long as you are careful when you operate the crown, it will not strip. If you keep it wound, you will only have to hack the time every few months, unless you travel different time zones.
