I was worried, but Korean language support works well. Korean language is supported. Other functions are mostly similar. There is no AOD function. The Ultra is a bit large.
It is very different from the product description. The price fluctuation is too severe, and after placing an order, they claimed it was shipped without actually delivering it. In the end, they processed a refund and I had to reorder, which arrived 3 days later than the promised delivery date. It doesn't even turn on, and the service attitude is completely negative 1000%.
I bought it as a gift, I charged the watch, it's simple. Physically it looks very good, the center and top buttons work well, the bottom one is harder. It comes with a spare metal strap and a plastic stand for the edge of the watch.
