Smart watch lot

4 smart watches that all power on and work. The first one, the one with the purple band, works great but it'll need the buckle replaced on it bc it got knocked off. Also, I'm not able to find the charger that goes to it but I'm sure u can purchase a replacement cheap. It has an app that u download on your phone that the watch syncs to and it tracks your sleep, heart rate, and a few other things. The 2nd and 3rd one both use a micro USB charger and comes with a bunch of diff apps on both and u can get calls thru them. They also both have a camera but honestly, they don't have the best quality. And the last one with the blue strap is like the 2nd and 3rd one and it has a camera on it as well. The screen does have a crack, as shown, so some of the diff options don't work right bc the screen is so sensitive and the crack messes it up. But all 4 work and are prob better for younger children who u aren't ready to purchase a more expensive watch for just yet. Selling all 4 and not separating
