This is an automatic winding model of a SEIKO divers watch. The model number is 7S26-0020. I believe it is an SKX009. The bezel was originally Pepsi-colored, but as it was in the image, I replaced the bezel with a blue and black bezel. I think the operation with the crown is not a problem. The screw-down crown also works properly. The glass surface has a scratch from 8 to 9 o'clock. It's deep enough to catch your fingernail. There are also small dents from 5 to 6 o'clock. The case has fine dents and scratches from use. The bezel has a unidirectional rotating function. The top part and the 12 o'clock position are slightly misaligned. It rotates with a satisfying click. The daily rate fluctuates around -30 to -40 seconds according to the timegrapher. Since it has not been overhauled, it should improve with adjustment. The belt has been replaced with an aftermarket rubber belt. I will include the original stainless steel belt. Please note that there are no end links. The dial is navy blue, so it has been customized to a Batman specification. Other than that, it is original, so maintenance is possible at SEIKO or a watch store. Please understand that the condition assessment is based on my amateur judgment. Please ask any questions in the comments. Seiko Divers watch Black Boy Automatic winding Vintage Men's Wristwatch
