Won't unscrew the back because it keeps slipping out of the indentations. Also, it states "Adjustable Repair Tool Kit" however, it does not include the yellow holder that is shown in the picture, just the blue wrench.

I needed to change a battery on a LARGE Bulova watch , I priced other tools on E Bay and they were pricey or size specific . I bought this with a lot of reservation because the price was so low but I thought if it works once its way cheaper and less hassle than finding a jeweler to do it . It turned out to be adjustable from very small to way bigger than I needed and is very sturdy . All metal and easy to adjust and use , I don't know what the units that cost 15 times more can do for my situation that this one won't .

This is not an "Adjustable Rectangle Watch Back Case Cover Opener Remover Wrench Repair Kit". At least in my layman judgement. It is not to remove the back case cover for "rectangle" watches. As near as I can figure, it is to remove the back cover of waterproof watches. It has two protrustions that fit in the indented case and you turn it to unscrew the "round" back cover. If you will note in the picture with the ad, it shows a round watch. I did use it to unscrew the round back cover on one my waterproof watches and it worked just fine.

This little gadget does exactly what it is advertised to accomplish\! It allows you to open the back of various "screw back" watches to replace the battery. These watches are often the deep six waterproof variety which allows the back to screw down on a gasket to seal the watch and provide water protection. Care must be taken, however, when the watch is being disassemble to make sure the seal is not torn and free of debris and grease. In my quest for a means to remove the backs of several of my watches, I viewed a lot of YouTube videos. There are some that show removal of a back with something like putty and another uses a pair of needle nose pliers. Even a pair of scissors were shown. Most are far more costly than this simple gadget and often have an inherent danger of scratching up the back of the watch when they slip or when the back refuses to budge. This device is cheap and simple and worth every penny even if you use it only once. It works much like a crescent wrench by utilizing opposing screw threads to cause two attached prongs to move to the exact dimensions on the back of your watch. Once you put the device into the notches, you can rotate this sturdy devices in a counterclockwise to unseat and unseal the back for access to the inside of the watch. Once you have installed the new battery you then use this device to rotate the screw back clockwise until it is tight against the seal. The seal should be cleaned with a soft brush before attaching the back. And on most watches, the required battery number is etched on the outside of the back. Highly recommended but likely this is a lifetime purchase! Read full review

This tool is designed to help undo the back of watch cases for battery changes. It unscrews the rear case of water proof watches. Non water proof watches have a "Press fit" and are opened using a different tool. This tool is very well made and of a high quality considering the price of the unit, its fast and very effective. I would highly recommend it to even novice people who want to change their own batteries in their watches.
