**Men's Stainless Steel Quartz Analog Watch with Date Calendar - 5ATM Waterproof Business Casual Dress Watch for Office, Daily Wear & Outdoor Activities**

Screw down case back. Heavy watch in my book means higher quality and this is heavier than my Invicta. Bracelet feels good on the wrist. I have not opened the case to see if its a Japanese Quartz or a Chinese Quartz but I've been wearing it for a couple weeks and have gotten compliments on it. I bought the blue one and am now thinking about getting the black to add to the collection. Would buy more if they would come out with other designs.For the money this is hands down the best diver you can buy. The watch looks great, the lume lasts all night on the hands and the pip on the bezel. The movement is a Miyota, and keeps perfect time. The bezel has a great action with almost zero back play. The bezel insert was off just slightly, but is easy to remove and replace with either double backed bezel tape or any water resistant glue. The butterfly band is great, however only has hollow end links, but at this price point one can’t complain. I put mine on a silicone single pass nato strap and it looks great. The watch is water resistant to 50 meters as claimed, as I have showered and swam with it and have had zero problems with water penetrating the case.the band i saw many complaints in review and wanted to see what the issue was - I though maybe the locking system got bent or something- fact is there really is not one the watch is good the band worst ever seen- you buy this watch bet you be buying a new band- it the kind with a metal flat piece of steel and when you fold the watch band to lock it it not long enough to keep it locked and bending it wont help you either glue or tape it shut or get a better band- it is pointless- the removal pin tool works if you have very good eyes- and if you can align the holes on either side of the holes to the pins- good luck?? obviously they included this knowing their band is the worst ever- but if you just need a good watch thats what you get and thats itGreat looking, comfortable to wear.Sadly you can't change it the day/date without doing it by winding it in the old fashioned way which takes forever.But as said nice looking and still good watch for the price.Wish it had instructions on how to make band smaller. Watch band to big but love the watch.Watch is very heavy. However the quality seem good. I wanted it for myself even though it's say men but it was too heavy for my hand.My boyfriend loved this watch as a Christmas gift but the band has clasps on both sides and when you move your wrist it unlocks and the watch falls off. Very poorly designed, I had to returnThe watch is simply stunning, especially considering the price. High quality components, well put together. I had a minor complaint and the seller resolved the issue promptly with personal attention and grace. Highly recommend.
