I bought this Citizen Eco-drive to replace one I'd given my wife nine years ago that finally failed. We discovered that the power unit was fried and they didn't make replacements. The original was much more expensive than this, but we didn't know it was ultimately a throwaway.
This watch is the same technology but we expect it to crump in a few year. It's still a beautiful watch, and the eco-drive is totally hands-off as long as it lasts. No batteries to maintain, no problem if you don't wear it for a long time. It keeps itself charged with light input through the porous face.
My wife loves it and I plan to replace it every five to nine years. Oh well!
The only negative is that you need to check dimensions carefully on the Amazon watch site. All watches are displayed as approx the same size, This one is smaller than I expected (my bad) but it looks good on her wrist and she can still read the time on it. Next one will have to be larger.Buy Citizen Women's Eco-Drive Silhouette Two-Tone Watch #EW8664-53A!
