Once you have your watch case open, eventually you will need to close it again if you want to wear it. Luckily, closing a watch back is almost as easy as opening a watch back when you know what kind of watch case back you have. In this article, we will be addressing how to close a screw down watch case back. These watch case backs have notches regularly placed on the case back.
The first step once you are ready to close a watch case is to check the watch gasket. Gaskets can get old or be damaged during repair – if you are concerned about the state of your gasket, replace it. For help on this, check out our article on How to Replace a Watch Gasket.
Now that you have completed your watch repair and have determined that gasket is in good condition, you are ready to close the watch back again. Place the back on the case, making sure it is not tilted on an angle. Start by tightening the back with your fingers, turning it clockwise.
When you can no longer tighten the back with your fingers, take the case opener ball and position it against the case back again. Once you have a good grip on both the watch and the friction ball, continue tightening the back the rest of the way, turning it clockwise.
When the back will not tighten the back anymore, you know the back has been securely replaced on the watch. Now you can reset the watch and continue to wear it.
