The Optimum OS11 watch is a sailing specific designed for the needs of the active sailor. Handy countdown features (specific to sailing starts), a sync button and water resistant/shock resistant construction make this watch a great choice. The watch is cased in plastic with a fully integrated strap. An excellent lightweight and high performance watch for any sailor!

    Lightweight sailing watch with great audible countdown.

    The OS11 watch is great for sailors who want a lightweight wrist watch instead of the larger Optimum OS3. Personally, I don't look at the screen very often within three minutes of the start of a race; I just listen to the audible countdown sequence. As a result, the slightly smaller digits on the OS11 compared to the OS3 is not a concern for me. The size of the digits on the OS11 is still quite reasonable. In my experience, no sailing watch is indestructible, but the OS11 is going strong for me after several seasons of use.
