For sale here is my Marathon GSAR, which was customized to lefty/destro by Wilson Watch Works using a specialized white on black date wheel. These are about as rare as they come and the process costs at least $200 on top of the price of the watch itself. The condition of this example is solid. It has been worn and has slight marks here and there, including desk diving action on the clasp. The watch head and the rest of the bracelet are in great shape but again, this one has been worn. Everything works as intended. The photos accurately indicate the condition.  WWW is also an authorized Marathon dealer and specializes in customizing Marathon so everything was done professionally and with great attention to detail. I had that work done in 2020, I think, and the watch has been worn very sparingly since then. If you’ve never worn a Marathon GSAR, the crown can be tough on the back of your hand, making the lefty conversion a great option.  This one is a very full kit including a Marathon bracelet with all links. It’s currently sized for my own 6.5 inch (16.5 centimeter) wrist. To be clear about what’s included, you have the lefty GSAR watch head, the full bracelet, a Marathon box/microfiber, and two Marathon rubber straps, one black and one OD green. I am looking for $1200 including PayPal and shipping to the US only. No international shipping and no returns.
