I love my watch and everybody else does to. I tell everyone that Im keeping a eye on the time. LoL A lot of the reviews I read about it said it didn't keep good time. I have not had any trouble with that at all. With the pupil moving as the second hand. Im sure the battery will not last as long as it would in other watches. Because of how big it it. But thats ok with me, I can change a battery in a watch.
