About the product

Originally issued to Canadian Search and Rescue (SAR) Techs in the early 2000s, the SAR-D marked the beginning of Marathon’s SAR dive watches. The re-engineered OSAR-D builds on that legacy with upgraded MaraGlo illumination, larger indices for quick reading, and an improved cyclops date window.
