Ronstan ClearStart 65mm Black Sailing Race Timer

The Ronstan Clear Start Race Timer 65mm in Black/White takes the most popular sailing watch design and scales it up for crew-wide visibility, combining bold styling with true racing functionality. Oversized 16mm digits on a large 65mm face make it easy to read from across the boat, whether worn on the wrist or mounted to the hull, mast, or boom. Large, easy-press silicon buttons with a highlighted Start/Stop button keep operation simple even in demanding conditions.

Race Mode includes multiple pre-programmed start sequences such as ISAF 5-4-1-0 and match racing, plus a user-set option. The SYNC function lets sailors resynchronize the countdown if the start sequence begins early or late, while loud intuitive sound signals indicate exactly where you are in the sequence. At the end of the sequence, the timer can auto-repeat the countdown or switch to counting up to track elapsed race time.

Beyond racing, the Race Timer offers everyday functionality including 12 or 24 hour time format, day/month or month/day date display, a daily alarm, and a chronograph. A luminescent backlight aids visibility at night, and the rotating face allows for flexible mounting orientation. It's rated water resistant to 5ATM (50m/150ft) with double gasket seals and is highly shock resistant. The 30mm wide stretch nylon band with security loop and flush fit buckle keeps it secure whether worn or mounted. Explore more in our watches collection.
