I purchased this here. It's a handmade wristwatch from Kurukitei. The size is approximately 4.5 cm in both length and width, as measured by an amateur. It's a bit large, but I, a woman, could wear it without any problem, so I think it can be used by both men and women. I had the battery replaced at Kurukitei before, but it's currently not working. I'm looking for someone who will replace the battery and use it. Since it's been several years, the strap has some wear and tear, and some verdigris has appeared. Please check the photos. If you have any questions or would like additional photos, please feel free to comment. No price reduction, sorry. #Kurukitei #Handmade #Wristwatch
