I'VE HAD THIS WATCH FOR 10 YEARS AND NOT ONE ISSUE.
I have owned my E650 watch for 10 years now and I have never had 1 issue with it functioning. I worked a pretty demanding labor job for a telecom company with it every day. The only complaint I have ever had was the "gold" on the watch band faded fast after I purchased it. Otherwise, this bad boy has kept perfect time and been a real workhorse for all of these years. I just purchased an upgrade to the E660 so I am hoping to have both to continue running so I can pass them down to my sons.
I brought this watch about six or eight years ago while on a cruise and love it. My only issue is the time no longer adjusts to my location - traveling to California from Pennsylvania stayed on NYC timezone instead of automatically adjusting to Chicago then Denver then LA after a few years.
I purchased this watch a few years ago and it's been one of my better that I own, Echo Drive feature is second to none, If the time and date and other features need to be set citizens website has all the information needed. Every time I wear this watch I get compliments it is not only a good timepiece it is very attractive and works all the time.
