When you wear the watch in the evening, you receive a detailed analysis of your sleep along with tips on how to improve its quality. There are 70 sports modes to choose from, including indoor and outdoor exercises. Once you finish your workout, you can create a training report to document your achievements. The watch is waterproof up to 2 ATM, allowing you to swim without worrying about water damage. The waterproof rating of up to 2 ATM is based on laboratory tests. Actual performance may vary depending on the product, user habits, and environment. Do not wear the watch while diving, water skiing, in hot springs, or during other activities where you may experience high speeds or deep immersion.
