In September 2009 my wife bought a Citizen quartz eco-drive : EW8XXX/EP4XXX/Cal.No.B023, serial : EW7060-57E.
However, after less than a year it stopped working . Ever since that time it has been going to the company maintenanace in Egypt without any success that it could work again .
Unfortunately, i am very much dissatisfied i bought such a product especially that it was an expensive .
