Innovative Race Functions with Bold New Styling:

Ronstan’s ClearStart™ race timer and watches combine contemporary styling with true sailing functionality. They feature large buttons, easy to read displays and advanced intuitive programming designed specifically with the racing sailor in mind. Developed with input from some of the world’s top sailors, ClearStart™ watches and timers are sure to set the standard for years to come. If you’re looking for a simple competitive edge, the difference is ClearStart™.

Large Quick View Displays:

The entire ClearStart™ range features oversized digit displays for easy viewing. The Race Timer presents huge 16mm (5/8”) numbers that can be easily viewed by the crew when mounted to the boom or mast base. The 50mm Sailing Watch displays only slightly smaller 13mm (1/2”) digits, which can be quickly viewed at a glance without taking your hand off the helm, and the compact 40mm Sailing Watch still has impressive 10mm (3/8″) digits.

Race Sequence Resynchronization:

All racing sailors know how hard it can be to get the watch going at the exact second the start sequence is commenced. With the handy SYNC function, you can quickly resynchronise the ClearStart™ to the official race time. A simple press of a button allows you to drop down to the next minute, allowing you to get your starting sequence back in perfect SYNC at the next opportunity.

Pre-programed Race Sequence Sounds:

The intuitive ClearStart™ sound signals let you know exactly where you are in the start sequence without looking at the display. Pre-programmed with World Sailing 5-4-1-0 and Match Racing start sequences, it can also be programmed for other count down sequences by the user. Sound signals can be turned off if desired.

End of Sequence – Count down or Count Up:

Depending on the user’s preference, the watch can be set up to repeat the count down at the end of the sequence for general recall restarts, or to start counting up to track elapsed time.

Multi-line Display with Real Time:

No need to switch between count down and time modes because the actual time is displayed below the count down time on the new multi-line ClearStart™ display.

Daily Life Functionality:

From waking up for work to working out, a ClearStart™ watch is also great for everyday activities. Standard modes include 12- or 24-hour time format, date in day/month or month/day format, daily alarm and chronograph (stopwatch).

Luminescent Backlight:

Bright, full-face electroluminescent backlighting is easy to read at night and can be turned on temporarily for a quick view.

Water and Shock Resistant:

Designed to survive the rigours of competitive sailing, ClearStart™ watches and timers are water resistant rated at 5ATM and highly shock resistant.
