49MM The Apple Watch Ultra, which needs no introduction, is used. I bought it from STC. Of course, among the watch's features is that it works underwater up to a depth of 40M. It also has sensors to measure depth and water temperature, and can be used to calculate swimming and diving exercises. It features a blood oxygen sensor, can measure blood pressure, calculate heart rate, track sports movement, and measure breathing. The watch can be used as a navigation device to know directions, save points, and save the return path as it is equipped with a GPS system and also supports a cellular chip. It comes with several bands, more than 10 types. Selling to the highest bidder, and sustenance is from God.
