This is a SEIKO Speedmaster. It's a quartz model, and the battery was replaced with a new one in early December. The model number is 7T52-6A30. This model is no longer in production. There are scratches on the glass surface from the 9 to 10 o'clock position. There are also scratches around the 2 to 3 o'clock position. They are deep enough to catch a fingernail. I believe the crown operation is fine. The stopwatch function also works. There are some scratches on the case and the band. The size up to the crown is about 39mm, and the wrist size is about 16cm. There are 3 extra links. There is a presentation box, instruction manual, an unwritten warranty from the time, and extra links. Please understand that the condition assessment is based on my amateur judgment. Please ask any questions in the comments. Seiko Wristwatch Men's Vintage Retro Chronograph Speedtimer
