Used for about a year. Market price is around 14,000 to 15,500 Taka. You can control the watch through the Huawei Health app, and measure heart rate and SpO2. There is a slight scratch on the lower side of the watch body, which is not visible when worn, and this has caused no issues with the watch. You can change the watch strap. The watch comes with the original box. The price is negotiable, but not by much. If you have the budget and the intention to buy a good watch, please send a message. Thank you.
