This is the second automatic watch I got for my husband-the first one was defective-so I returned it for another Diver style watch-also automatic-we have not been in the ocean or pool yet this one too seems to be losing time. I have never heard of an automatic self wind do this-I will give it a few more days and if it loses time I will have to return it. Surpirsing for an Invicta to do this. I buy alot of things from Amazon and this has been a pain.
