ClearStart™ 40mm Sailing Watch- Blue

Innovative Race Functions with Bold Styling

The most popular sailing watch in the world just got better. Ronstan's Clear Start™ race timer and watches are completely updated with bold styling and true sailing functionality. Besides the fresh look 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, Clear Start™ 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 Clear Start™.

Large Quick View Displays

The entire Clear Start™ range features oversized digit displays for easy viewing. The compact 40mm Sailing Watch has impressive 10mm (3/8”) 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 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 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 multi-line ClearStart™ display.

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, 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 fiber reinforced resin, with a resilient and super-comfortable silicon band. 

Race Mode:

  • Multiple start sequence options – World Sailing 5,4,1,0, match racing, user set.

I didn’t receive the item and I let Amazon know the item was not delivered. Apparently, they don’t care to follow up with my lost order. Hummm, I wonder how the owner of Amazon would solve this problem.

Closing it when you have a ring.
Color: Black, Color: Black
Its a nice box but the problem i have with it is the middle piece. It does not give enough room if you have a ring that sits high like a cocktail ring. And same if you have a pendant necklace in the necklace area. You have ro really force it closed and i worry that it will put pressure on the items. It would work better without that middle piece for earrings or maybe if it were half the size. Closes fine when its empty but the minute you put a ring in the ring spot that has any kind of height you have to squeeze it shut. Its a good little box that you can put in a safe. Thats why i use it. Just to put my good jewelry in it and then secure it properly in a small house safe. Also ive already had the backs of a few earring pop off when I've opened the earring flap because it all rubs together. .

So cutie
Color: Cloud White, Material Type: Paper, PU
This is a bit large for a travel size jewelry box lol I really thought it was going to be a bit smaller than what it was. I can see why some of the ladies in the comments are saying they’re using it as their main jewelry box since they don’t have much jewelry for a standard sized jewelry box. With that being said, it’s cute and CAN be small enough for travel. It fits a lot and I got this one in particular bc I like that it has a bigger lower compartment for larger pieces. It’s a nice quality travel jewelry box. It’ll fit my needs. But if you have a knack for packing small and you value space. I’d say skip on this one or do due diligence to double check the measurements to see if it’s something you’re okay with packing.
