Ronstan RF4055 ClearStart Sailing Watch 50mm Black/Grey

Innovative Race Functions with Bold New Styling

The new Ronstan RF4055 ClearStart Sailing Watch is a completely new design with an updated contemporary style and new materials, alongside all the familiar timing features and functionality that the ClearStart range. The lens is now made of ultra-clear, scratch-resistant mineral crystal, recessed for extra protection. The new case is glass-reinforced polycarbonate with stainless steel structural tension ring around the hardened crystal lens resulting in an exceptionally stiff construction. The band is now injection-moulded in a soft-feel silicon for added resilience, flexibility and comfort, and can be removed and replaced when needed. Nylon reinforcements embedded in the band add strength at stress points. Buttons are shaped to a lower profile to avoid accidental activation and they act on precision stainless push rods, sealed with triple gaskets in stainless tubes within the watch case to prevent moisture entry.

Large Quick View Displays
The entire Clear Start range features oversized digit displays for easy viewing. The RF4055 displays 13mm (1/2") digits, which can be quickly viewed at a glance without taking your hand off the helm to read.

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 Clear Start 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-programmed Race Sequence Sounds
The intuitive Clear Start sound signals let you know exactly where you are in the start sequence without looking at the display. Pre-programmed with ISAF 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, this 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 Clear Start display.

Bold and Functional Styling
Redesigned for a new generation, the Clear Start range offers clean modern styling without sacrificing usability. Available in attractive colour combinations that can be worn anywhere, the Ronstan RF4055 ClearStart Sailing Watch features smooth edges so lines will not get caught in the heat of battle.

Daily Life Functionality
From waking up for work to working out, the Clear Start range is also great for everyday activities. Standard modes include 12 or 24 hour time format, date in day/month or month/day format.

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, Clear Start watches and timers are water resistant to up to 50m (150ft) and highly shock resistant.
