This is a Seiko Prospex SBDN013. It's a full-titanium model diver's solar watch, making it very easy to use. It's incredibly light and the design is timeless. The dial is a beautiful black with a sunray finish and excellent visibility. The luminous paint is great and glows brightly. The unidirectional rotating bezel operates very smoothly and feels great. The case size is approximately 40mm, making it suitable for those with slender to average wrists. It's a Japanese-made watch, so the size is designed to fit Japanese people well, and it's very comfortable to wear. My wrist size is approximately 17cm, measured by a non-professional. Please understand that there may be slight variations. There is no need to worry about odors as it comes from a non-smoking and non-pet environment. Please be aware that this item has been previously owned. Size details may vary depending on the conditions. The photos have been brightened to make the details easier to see, so please understand.
