I've been wearing my Seiko 6309-7049 on and off since I purchased it at the age of 13. I had put the watch on layaway at a local jeweler and paid every week, usually about 20 bucks a week until it was paid off. Back then (around 1989) the watch was over $200. I wore it for most of my teenage years then on and off during my 20's. I had other cheaper watches the wife would buy me but the Seiko was always my favorite. Then it was no watch for a few years and relied on the cell phone for time.
A few months ago I put it back in service. The original rubber band was stiff and cracked so I replaced the band. It's a self winding watch that loses a minute a week so every 2-3 weeks I need to adjust the time. Other than that the watch has been bullet proof it's entire life. The back cover has never been off of it. Seiko really hit the ball out of the park with this watch movement and it's been used in other similar Seiko's over the years.
