Howdy! I have been using Garmin fitness watches for several years now. They have special features that help me monitor my health 24 hours a day. The watch measures the level of oxygen saturation in the blood, monitors the energy level of the body, in addition, it helps to monitor stress, sleep, as well as the pulse rate. If you are interested in buying such a watch and want to buy it for yourself, then call garmin phone number and the manager will help you choose the model you need.
