This is a chronograph quartz wristwatch from ALBA, a sub-brand of SEIKO. The model number is Y182-6B10. As expected from SEIKO, the build quality is beautifully finished. The battery was replaced, lightly polished, demagnetized, and treated with Crystal Guard in December. However, deep scratches remain. The glass surface has a scratch near the 9 o'clock position. It doesn't catch on a fingernail. Operation with the crown seems to be fine. The stopwatch also worked for about 20 minutes and could be reset. The alarm at the 6 o'clock position can be operated with the lower right crown. Time adjustment is done by pulling the crown out two steps, and the alarm sounds when pulled out one step. Please keep it pushed in normally. I don't know what the lower left button is for. As shown in the images, it's an old model, so it's a small size by today's standards, but I think it's an easy-to-wear size for Japanese people. The dial size is about 30mm, the size to the bezel is about 34mm, the size to the crown is about 39mm, and the wrist circumference is about 16cm. There are no extra links. With its chic design and easy-to-wear size, it would be easy to match with a suit if the wrist circumference fits. Please understand that the condition assessment is based on my amateur judgment.
