Stainless steel automatic watch with a black dial and date display. BLACK FRIDAY price until December 1st! First come, first served! - Brand: SEIKO Prospex - Model: Automatic watch - Color: Black - Material: Stainless steel - Band type: Bracelet - Features: Date display This is a Seiko Prospex Baby Tuna. This model is not sold in Japan. I am selling it because I always use a smartwatch. Of course, it is in perfect working order. I have been using it constantly since I bought it. It is waterproof, but I have not used it for diving or swimming. *I have not used it during bathing or showering either. It is an automatic watch, so there is no need to replace the battery. The way the second hand moves, unique to automatic watches, gives it a mechanical feel that I love. The daily error was about a few tens of seconds, so it was not inconvenient. As the nickname "Baby Tuna" suggests, the case has a silver and metallic feel like a "tuna can," and I liked its ruggedness. People who see it for the first time often say, "That's an expensive-looking watch, it's cool!" The weight of 187g and the metallic feel gave me a strange sense of tension when I put it on, like "Alright, time to go to work!" lol It has been used for about 5 years, so there is some deterioration commensurate with the years. I have neglected to clean the band and the bezel around the main body, so I would like those who are concerned to clean it again. However, there are no noticeable large scratches or stains. However, there are fine scratches on the stainless steel parts due to aging. The belt links and parts that were adjusted for length are included. The bezel can only rotate to the left, and it has some stiffness when rotating. There are no cracks or breaks on the glass surface. This is a genuine SEIKO model sold overseas, but the box is not a SEIKO box, but a general-purpose box as it was when purchased.
