Unfortunately, very bad experience from using this specific watch, regarding its battery and charging... In the beginning, the battery lasted at most one day with normal use. After 3 to 4 months, it needed to be charged 2 to 3 times a day. I sent it for technical inspection, they told me that this was its normal operation. After a while, I sent it again as it no longer charged at all and remained dead. They replaced the battery, which lasted for 2-3 months, and today, almost 1 year from its first purchase, the watch cannot be used at all... Stay away!!! Your money is wasted!!
