This is the smart watch (health watch / model: BSN-SW80-0018 / product number: CM3-SW) distributed by Chocozap. I tried it for only one day, but the feel of it didn't suit me, so I'm selling it. Operation has been confirmed with the FitPro app. Basic functions such as step count and heart rate worked without any problems. It was only used for one day, and there are no noticeable scratches or stains, but please understand that it is a used item that has been opened and used once. Shipping will be done with simple packaging.
