Large Quick View Displays

The entire ClearStart range features large digit displays for easy viewing. The Race Timer presents huge 16mm (5/8 inch) numbers that can be easily viewed by the crew when mounted on the boom or mast base. The 50mm Sailing Watch display is only slightly smaller with 13mm (1/2 inch) 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 inch) digits.

Race Sequence Resynchronisation

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 countdown sequences by the user. Sound signals can be turned off if desired.

End of Sequence - Countdown or Count Up

Depending on the user’s preference, the watch can be set up to auto repeat the countdown 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 countdown and time modes because the actual time is displayed below the countdown 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 (stop watch).

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 rigors of competitive sailing, ClearStart watches and timers are water resistant rated at 5ATM and highly shock resistant. Watch housings are moulded in rugged fibre reinforced resin, with a resilient and super-comfortable silicon band.

    Great starting watch

    Whenever I line up on a starting line, I make sure to use my Ronstan Clear Start Timer. What makes it such a great watch is that it beeps every minute until one minute and then every 10 seconds until 15 seconds and then beeps twice every seconded until go. It might sound confusing but trust me, when you’re trying to defend your hole with 14 seconds until the gun, having that external noise is a life saver. My preference is to wrap it around the boom.
