Large, Quick-View Displays

The entire ClearStart™ range features oversized digit displays for quick & easy viewing so that you never have to take your hand off the helm.

Race Sequence Re-synchronisation

Racing sailors know it can be hard to start a watch at the exact second the start sequence is commenced. But with ClearStart’s SYNC function, you can quickly re-synchronise to the official race time. And, a simple press of a button allows you to drop down to the next minute, getting you back in perfect SYNC at the next opportunity.

Water & Shock Resistant

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

Pre-programmedRace Sequence Sounds

ClearStart’s 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, users can also program ClearStart™ for other count down sequences.

End of Sequence –Count Down or Count Up

Depending on the user’s preference, the
ClearStart™ 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 current time is displayed below the count down time on the multi-line ClearStart™ display.

Daily Life Functionality

From waking up 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.
