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.

Stylish and eye-catching watch with great value
Color: blue watch for men
This watch looks much more premium than its price suggests. The blue dial combined with the two-tone stainless steel gives it a clean and elegant appearance, making it suitable for both formal and casual wear. The diamond accents add a nice touch without feeling overdone. The quartz movement keeps accurate time, and the date feature is convenient for daily use. The luminous hands are helpful in low-light conditions as well. The build quality feels solid, though the band may need adjustment for a perfect fit. Water resistance is fine for everyday situations like hand washing, but I wouldn’t rely on it for heavy water exposure. Overall, a good-looking and functional watch that offers excellent value for the price.

Great watch, would recommend
Color: blue watches 58, Color: blue watches 58
I really like this watch because it looks amazing. It’s much lighter than I expected, so it’s comfortable to wear all day at school without feeling heavy. When I first got it, the metal band was a little bit squeaky, but after wearing it for a while, the noise completely stopped. I had to remove a few links to make it fit my wrist, but the adjustment was actually really easy to do yourself. The clasp is great too it stays closed and it doesn’t pinch my skin at all. The blue and gold colors look awesome together, and it’s definitely a great watch for the price

My new favorite watch. Simple home improvement needed
Color: all black watch mens, Color: all black watch mens
Despite having many reknown brand watches in my collection, these inexpensive Olevs watches are now my favorite. They look nice, cost practically nothing and so far are very accurate (10 day review). Little to worry about if lost or damaged. PROS: 1. Inexpensive $40/each. 2. As stylish as other fashion watches 5x-10x more expensive. 3. Watch Crystal (i.e., glass) has a unique, faceted shape, which reflects light, feels "Manly" and matches faceted bezel. 4. Light weight and slim case; fits small wrists nicely (I have 6.4" wrists). 5. Accurate - two watches tracked over 10 days. Watch one: -7 seconds/10 days. Watch two: +2 seconds/10 days. 6. Illuminescent (i.e., glow-in-the-dark) hands and watch face look decent in dark. CONS: 7. Lightweight and cheap material - durability is questionable, especially coatings. 8. Bracelet/band links have excessive gaps to each other and rattle badly, making watch noisy and embarrassing. *Home fix* 9. Faceted Crystal can make it difficult to see exact time, because of light reflection. 10. Single clasp on bracelet could easily open inadvertently, vs double clasp. 11. Crown is not threaded and spins freely, even when closed (doesn't change time); likely poor water proofing and crown can easily open. 12. Difficult to set time accurately; crown movement is figity and closing crown can cause hands to easily move. 13. Second hand doesn't exactly line up with tick marks making it difficult to know if actual time is before, or after tick mark. *AT HOME FIX*: To fix the noisy bracelet, simply cut to length a piece of waterproof medical tape 15-16mm (5/8") wide, then attach to inside of clean bracelet, while spreading the links apart with your finger (i.e., stretch band). Do this on each bracelet, but don't cover clasp. Tape will need to be replaced, as it gets dirty, but it makes watch quiet. - Watch dimensions for collectors - A) Case Diameter (to Crown): 44mm B) Case Diameter: 42mm C) Lug-to-Lug length: 50.5mm D) Case Thickness (Top of Crystal): 12.6mm E) Strap/Bracelet Width at Case: 20mm F) Strap/Bracelet Width at Clasp: 18mm G) Weight 6.4" wrist size: 100g (3.5oz)

It's a watch
Color: blue watch for men
Not a bad watch. Cheap, looks good and works. Take it to your local jeweler and they can pop the links out in no time.
