I purchased a black monster about 4 months ago. It ran +30sec/day out of the box so I sent it back to Seiko to be regulated. It came back at -30sec/day, so I sent it back again and it is now perfect (+/- 1sec/day). HOWEVER, now the day and date changes between 7pm and 10pm. Does anyone know what is going on here? I have not found a way to correct this and I don't plan to take the back off the watch myself because it would void the warenty. I will likely send it back again. I just wanted to see if any one has dealt with this before. Thanks!
