OPTIMUM TIME has released a groundbreaking new product.

While retaining the functionality of the best-selling OS3 series, we have added new features.

Part 1.

It's rechargeable and powered by USB . It takes up to two hours to charge, and because the power consumption when the timer isn't in use is very low, it was able to withstand 700 start sequences in testing (meaning it doesn't need to be charged for roughly six months). It's also charged by clipping it onto the outside of the case, eliminating the need to open the case and the risk of seawater getting in.

Part 2.

It has a vibration function, and the sound is hard to hear on windy sea surfaces, but when you wear it on your wrist you can hear the countdown by the vibration.

Part 3.

A full-screen countdown begins one minute before the serious race. You can't just stare at the clock, so the countdown starts in large letters on the screen, 59 seconds before the start.
