H2O Time - Sport Kit for Apple Watch

Enhance Your Apple Watch Experience

Ultra-Soft Silicone Band

H2O's proprietary silicone material provides an extra-comfortable fit for all-day use in and out of water. The hyper-elasticity, soft-feel, and easy adjustments help you to find the perfect tension needed to optimize heart rate readings.

Protective Sport Case

Bring your Apple Watch on all your outdoor adventures. Rugged H2O case will protect your Apple Watch from nicks and scratches. Case fits Apple Watch Series 1, 2, 3, 4, 5, 6.

Improves Heart Rate Sensor

Patent pending technology in the H2O case is designed to improve heart rate reading quality. The case keeps the watch in place against your skin while you swim, run or work out. By reducing the watch movement on your skin (a.k.a sensor Motion Artifacts), the case improves the accuracy of the heart rate readings.

The Apple Watch uses an Optical Heart Rate sensor (PPG) that is very sensitive to reading errors. Most errors are due to Motion Artifacts where the watch is moving against the skin, causing the readings to be erratic. With our patent pending design, we have been able to reduce the Motion Artifacts and improve the heart rate accuracy compared to the standard Apple Watch band.

Designed for Water Sports

H2O Case is form-fitted around the heart rate sensor under the watch, so less water can enter to affect the heart rate sensor. (H2O Case does not make the Apple watch waterproof.) The H2O Band is rugged and secure, something you can trust to take with you surfing.

Very good Band and Case

Very good band and case, Im loving using it for surfing and daily basis.The only point that can improve is the rubber loop that are a little fragile, some of friends already demaged that.

Great product

Just got my second band, and was pleasantly surprised to see that the case protector is improved compared to last year’s original design. It is made from a sturdier plastic than the old rubber-like one. The band itself looks fairly similar. At any rate, great product. I like it so much that I keep the case cover on all the time, and just swap bands after my daily swim. Awesome product.
