Optimum Time OS Series 3 Sailing Watch

The original and iconic big yellow timer is still the top choice for competitors around the world today. If you need a robust timer, with an easy-to-read display, and exceptional sailing functionality, then this is the one for you. The OS3 can be strapped to a mast or comfortably worn over your sailing kit. The face rotates to give you the best viewing angle and the big buttons mean you won´t be left fumbling when the race is about to begin. The OS3 also features our essential sync button, which synchronises your countdown to the race control timer, ensuring you won´t miss the gun.
