This watch is by far the best bang for the buck of any watch for sale on amazon. I got mine for $38, unbelievable. Screw-down crown, screw-down back, uni-directional bezel, stainless steel case, WR200M, awesome band- you just cannot beat it. The band is a 22mm width fyi. I bought a used one a few months back and sold it for more than I bought it for. I just had to have it again since it is so cheap and beautifully crafted. Casio builds ultra quality products and their timepieces are no exception. Has not lost one second in five days. This watch is built like a tank and is somewhat larger than other "large" watches. I have a Citizen BM-6400, my crown jewel "nice watch", and this Casio is just as nice and more accurate. The case is around 43mm to end of crown so be warned, it is not a small watch but not gaudy either. The band is real rubber, and is very tight when buckled and will not slip out of the tail holder unlike a Seiko diver I have which has the worst diver band I have ever seen, the Z20. Just a nice all around watch for a great price. The engraved marlin logo on the back is a nice touch also. You will love this watch. BTW, mine came running and with the smudges on the back like others have. They wipe off easily.
