No matter what style it is, as long as you want, it may be an old model a few years ago, or a new model just purchased this year.From the outside, the Rolex watch case is exquisite, the watch band, the crown, and the English words are clear and complete, while the imitation watch case is rough and the text is slightly blurred.In my mind, 'value' is only 'brand story', 'historical story' and 'self-generated motivation'.
The optical heart rate sensor and charging connection on the back of the watch. The principle of the traditional optical heart rate sensor is very simple. It uses light reflection to measure the heart rate. If there is a slight change in the blood, the heart is considered to be beating once. You can actually check the heart rate during exercise. The user is still very useful.The sufficient evidence to support this view is that there is money.You can place the watch in front of the screen and turn it on to degauss, which will also he a positive degaussing effect.
