I bought this watch for a modification project thinking it was an all metal construction. I didn't read the description properly, which says the back is metal but doesn't say the case is actually metal, even though the title suggests so. The product photos are also deceptive, as the case looks like metal at first glance. If I looked closer I would notice a seam running down the side of the case giving it away clearly. I gave it two stars because the mechanism seems pretty solid and it comes in a nice sturdy zipped case that you can use. Also, the LED is blue, which is a nice change from orange.
