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.
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 hear 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 the sensor area affecting 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 into surfing.
