Here is my Seiko Quartz 7548 diver I got when in the US Navy used it for 20 years while in the Navy it took a beating and kept on ticking. It was really beat up after over 30 years worth of use got it in the early 1980's so had Jack at IWW fix it up now good for another 30 years. I guess you can say this is the watch I have owned the longest.
On the wrist when in the US Navy.
