I received the watch a few days ago.  It looks exactly like another watch on Amazon that is little cheaper (Casio Men's A158WEA-9CF Casual Classic Digital Bracelet Watch).  But the cheaper watch has no description of being a solar watch although the picture clearly shows a solar watch.  And there is no such watch on the Casio website.  But the one I bought is on the website.  Yes, Amazon's price is much better too.  I called Amazon and a watch representative said that they were two different watches but I think they might be the same based on the picture or the picture posted is the wrong watch.
At first, the watch would not charge and I was really disappointed.  I left it on a window sill for hours and it would blank out as soon as I covered up the solar cells.  I was planning on returning it the next day.  But then I decided to read the instructions.  It stated what was needed for the initial charge.  Normal fluorescent lighting was not enough unless one planned on leaving it under a light for 200+ hours.  I placed it on a window sill but this time I angled it so that the solar cells faced the sun directly.  After a few hours, the "sun" icon disappeared and the watch works now.  The instructions stated that additional amount of sunlight it needed to get a full charge after the "sun" icon disappeared.
This watch has a coin capacitor instead of a rechargeable battery.  The instructions state that if the watch is used a lot, then the capacitor will slowly lose its charge capacity and will eventually need to be replaced.  So much for batteryless.  Sometimes I think a Casio that uses a 10 year lithium might be a better thing.
The watch is not the prettiest thing I've seen.  But I like solar watches.  I have a Seiko Sports 100 solar watch.  The rechargeable battery finally went out and I replaced it with a regular silver oxide battery because I couldn't find a replacement rechargeable one.
The Amazon description states that the watch has a LED light.  No such thing!  Even the instructions doesn't mention a light.  I wonder if a light will use too much power for a capacitor that can hold a max of 14 days of power at full charge.  Note that this watch uses a capacitor and not a rechargeable battery like other solar watches have.  Many rechargeable battery solar watches hold a charge for much longer time.
The watch case is resin (plastic).  The top part is silver paint and the bottom is gray plastic.  I don't like this because it can break where it meets the band if one is not careful.  My Seiko digital solar is made of metal.  I guess using plasic keeps the price down unlike my pricy Seiko.
