I've been using it for about a week, and I don't think it suits me, so I'm putting it up for sale. The case and chain are from the overseas brand Anne Klein. Unlike no-name brands sold on Amazon, these are well-made. The case was about 4,000 yen. The chain was about 8,000 yen. I'll be using it normally, and I might stop selling it if I find it convenient, so it might deteriorate somewhat. The Apple Watch is not included.
