There are many reasons that you might need to open a watch back and a variety of watch tools that can be used. If you need to change your watch battery or to replace a watch gasket, straighten the hands and remove dust, or completely replace a watch movement you will need to open the watch to do the work. There are many types of watch backs that can be opened in a variety of mechanical ways that sometimes are very easy and can be done with very little effort and others that require a special watch back opener that are sometimes best done by a person with training or experience in watch repair.
Before you open any watch, make yourself a mental note; Is this a very expensive watch? If the answer is yes, be very careful in attempting to open the back. Even inexpensive watches can sometimes be very difficult to open and can be easily damaged. Always check if the band clasp will get in your way when you try to open the case: some metal bands make it difficult to work in the back because they are rigid and don’t leave much room for your hands to work. If you need to remove the watch band to access the watch case, check out this article on watch band replacement or watch band repair.

These three types of watch case back are the most common, but there are many other types of watch cases as well and many of these should only be opened by professional watchmakers or jewelers. Rolex, Baum Mercier, and gold watches all require special tools and care when opening them and it is best if this work and care is left to professionals because they are easily damaged. The best thing to do when you encounter an expensive watch is to leave it to a watchmaker’s care, they have the tools and support needed to ensure your watch remains undamaged during repair.
Another thing to watch out for is for watches that open from the front: if you look your watch over carefully and cannot see a way to open the back, you may have to remove the crystal to change the battery or complete your repair. We recommend that if you are at all unsure of removing a crystal, you should leave the work to a watchmaker. Most of all, we encourage you to keep an open mind and use a common sense before attempting to fix your watch on your own, if you don’t think you can do it, don’t be afraid of taking it to a professional.

If the watch uses a screw-back design, you can just use a rubber ball to remove it. You will need a soft, pliable, tacky rubber ball.
Most rubber balls can easily hold on to the back plate long enough for you to pry them off.

WHY is there no instruction for screwing the backplate back on the Wristwatch ? It seems impossible to re-engage the threads now that I replaced the battery, and put the back plate on the wristwatch. This is CHEAP Shark Army brand watch with a Japan Movement.
I do believe all of the ideas you have introduced to your post.
They are really convincing and will certainly work.
Still, the posts are very short for newbies. May you please extend
them a little from next time? Thank you for the post.
