Apple Watch Series 6 GPS + Cellular model Stainless Steel (Graphite) 44mm https://support.apple.com/ja-jp/111918 I was using this until recently, and there are absolutely no functional problems. I am selling it because I am upgrading. The maximum battery capacity has decreased to 70%, but I was able to use it without any problems from morning to night with one charge a day. There is a very small dent on the stainless steel frame in the upper left corner of the screen (see the red arrow in photo 7), but other than that, it is in quite good condition with no noticeable scratches, and I believe it is a good product. The charging cable is brand new and unused. Also, I am also selling a Graphite Milanese Loop (genuine), so please consider it as well. https://jp.mercari.com/item/m53539990547
