I acquired this from a long-established watch store. Operational Status: When not worn, it gains +1 minute over a 24-hour period. I think this is pretty good for an old mechanical watch. The crystal has a thin scratch of about 2-3mm near the center of the 4 o'clock position, but it's not very noticeable. The date change and hand setting functions work without any problems. Model Overview: • Movement: Seiko Cal.6119 (Automatic, 21 jewels, day-date) • Production Period: Primarily early 1970s (around 1969-1973) • Water resistance marked as "Water Proof" This model is equipped with the "6119 series movement," which is a representative of the Seiko 5 series. It was durable and easy to maintain, and was popular worldwide at the time. The day-date display is at the 3 o'clock position, with the day of the week displayed in English + another language (such as Japanese).
