Input: I didn't understand that this Seiko watch when defective would not be returnable like other Amazon purchases. Also, there is no manufacturer's warranty. Highly suspicious that this is 'new' and not refurbished or irregular. Have put in in light over and over again and it just doesn't keep time - one time overnight it los almost 2 hours. I had a smaller Seiko solar watch and it was excellent in every way but I couldn't see the date so I bought this larger one. What a huge disappointment and now I'm stuck with it. I saw another review that had the same complaint. Looks nice but useless. Only will buy watch with warranty from now.

HUGE disappointment-solar power charge doesn't hold and no decent warranty
