I bought this a while ago. The white rubber band has discolored because I didn't use it. I think it cost about 4,000 yen to replace it at the manufacturer back then, but it's likely more expensive now. The purchase price was around 40,000 to 50,000 yen each. The battery is currently dead, but it was working fine when I used it. I'm selling it because I haven't used it at all since I bought an Apple Watch. #Diesel #Nixon #MAX
