I have owned this watch for several years now. I have had no problems at all with it. It faithfully sets itself every night, and I have watched it work from all four main U.S. time zones. Never been to the Atlantic time zone, though (sorry, Maine).

Battery life is great! I have only replaced the battery once. Battery replacement was NOT a big problem, as one reviewer has previously posted. I replaced the battery myself, and it was not much harder than battery replacement with other watches I have had. You can buy a cheap set of micro screwdrivers from any hardware store for less money than you'd pay a jeweler or authorized dealer / service center to do it.

It is water resistant. I have worn it while swimming with no problems.

The only negative I can think of is that the finish on the watch (mine is the gray-tone version) is paint-on-plastic...it will wear off over time.

I can't think of any reason to replace it. I'm entirely satisfied with what it does, and it just keeps on working!
