HUAWEI WATCH buds - Black This is the black color, which is not sold in Japan. It's a unique smartwatch with earphones built into the watch. I personally think the sound quality is good. The battery life was also good for a smartwatch (it lasted about a week without using the earphones). It was very convenient, but I'm selling it because I'm buying separate earphones and a watch. The screen display can be set to Japanese. I will also include a silver strap and a cover to prevent the lid from opening during sports.
