GS 4520-8000 Grand Seiko, a hand-wound watch. I loved it very much, but I'm selling it because I haven't had many opportunities to wear it. It is said to be the highest-grade model in the history of Japanese hand-wound watches (some specially adjusted). Among them, the non-date version is refined and has a unique atmosphere. A re-edition was released last year, and I think it's a model that is currently attracting attention to the original. Purchased in 2022 and overhauled in the same year. I remember being told that the movement was in particularly good condition, with a daily rate of about 15 seconds. (Please note that this is based on my memory, so there may be some error.) There are fine scratches on the case, dial, and bezel, but the condition is quite good. Please check the photos. The strap has been replaced with a new one purchased at Kawasaki Sweet Road (I have tried it on once). Case diameter is 36mm. Please feel free to ask for additional photos or questions in the comments. Considering its age, the condition is quite good, but please understand that it is a used item and I am not a watch professional. No returns or claims accepted.
