This is a Seiko Astron Nexter SBXY063. It's a radio-controlled, solar-powered watch, so you don't need to adjust the time, making it very convenient. Made of pure titanium, it's also very light, allowing you to wear it without stress. I purchased it around July 2023, but I haven't used it much, so I'm putting it up for sale. I used it at least once a month, so there are some minor scratches from normal use. As you can see in the photos, there are thin scratches on the bezel and scratches from the band on the back cover. I would recommend that those who are very particular about condition refrain from purchasing. In my subjective opinion, as someone who is bothered by scratches, they are not very noticeable. If you would like to know more about the condition of the watch, please feel free to ask.
