This is a SEIKO Quartz GT. It's a refined and atmospheric vintage model with a calm green dial and simple indexes. It has a day-date display, with the day of the week in Japanese. The dial reads SEIKO QUARTZ GT. It's a quartz battery-powered model. The battery has been replaced prior to listing, and it is currently running without any problems. The case shows some scratches and wear from use, but the crystal is in good condition without any noticeable scratches. The leather strap is an aftermarket product. It will be shipped with the strap attached, so you can use it immediately upon arrival. Please purchase only if you understand that this is a used/vintage watch.
