I have two Bulova Precisionists, and while one of them after 9 months keeps time not within 10sec/yr, but certainly within the COSC standard that is often quoted. (~25s/y) the other one does not even meet that standard. They both did to begin with, but both have drifted off over the time I've had them. I checked in the instruction and warranty booklet and was surprised to note that there was NO discussion as to accuracy nor any wearing time recommendations. The only mention of their purported accuracy was in their advertising, and it appears that this has been seriously overstated based upon what I have read here. I think that the fact that there is no discussion with regard to accuracy in the official documentation, is telling.You have the Bulova explanation as well as the warranty and instructions. In essence the watch will likely perform within specs if you wear the watch as specified. If you want higher short term accuracy off the wrist then you will probably have to pay more. Or raher than fighting a losing battle with the service department you should ask for a replacement from the selling dealer.
