I have had this watch for a few months. It regularly loses time, generally a couple of minutes each day. I have found some "fixes" online but I am ready to return it.
I’ve worn this model for about 5 years. The eco battery no longer holds a charge for more than 12 hours. I put it in full sun daily for an hour, but the watch stops overnight.
I bought my watch before Christmas. I love the 'never needs battery' feature. It is keeping good time. My only issue is the luminous hands do not light up in the dark.
