Thank you for viewing. GPS Smartwatch, compatible with iPhone and Android [Sleep/Autonomic Nerve/Calorie Measurement/Music/Messages & Calls] [Japan Genuine Product] Purchased on Mercari around November of this year. The previous owner bought it new and used it about 2-3 times. I have used it for about a month. I think the health care features like sleep score are superior on POLAR compared to GARMIN. I thought, as expected, it's a smart watch from a Nordic healthcare manufacturer. Since I haven't used it much, there are no scratches on the screen. It charges without any problems, and depending on how you use it, mine lasted for 4 days. The color is black. No box.
