* Case approx.: 26x35 mm * Thickness approx.: 6 mm * Belt size: 185 mm, width approx.: 20 mm The biggest attraction of this watch is its "sweep second hand" (smooth hand movement) that moves like a mechanical watch despite being quartz. The 5S21 movement, which appeared in the late 80s, has no ticking sound of step movement, allowing you to enjoy the elegance of time flowing in silence. The combination of a clean white dial with classic Roman indexes and a luxurious gold case is truly a dress watch for adults. This is a very rare model that combines the ease of a battery-powered watch with the emotional appeal of a mechanical watch, showcasing Seiko's technological prowess. This is a collector's item that will give you a special sense of satisfaction that sets it apart from others. When listing, the battery has been replaced with a new one, so the operation is also good. In addition, a new high-quality genuine leather belt has been installed. You can use it comfortably immediately after the product arrives without any settings. If you have any questions or minor inquiries, please feel free to comment.
