Selling my Apple Watch as I'm upgrading to a higher version. It's the Nike edition with an M/L arm band attached and an additional backup band, both visible in the photo. I swapped the original S arm band with a friend who uses S, and I use M/L. All components, including the bands, are original. The sale includes the box and charger. Everything functions perfectly. There are some superficial scratches around the screen due to daily use, but nothing deep and no problem when the screen is on.

Note: There is no S size arm band, but two M/L bands are included, as shown in the photo.
Note: The battery health is on 78% but it lasts a day even if you track a 2h of activity.
