Automatic wristwatches are a popular type of watch. Many people enjoy the convenience of not having to wind their watch or set the time.


Your automatic wristwatch is a complex piece of machinery. It is made up of many moving parts that must work together in order for it to keep accurate time. Over time, these parts can become worn or damaged, and will need to be repaired or replaced in order to keep your watch running properly.

There are a few things that you can do to repair your watch yourself, but in most cases it is best to leave repairs to a professional. If you are not experienced in repairing watches, you could end up doing more harm than good. In this guide, we will show you how to identify common problems with automatic watches and what you can do to fix them.

If you have a specific problem with your watch that is not listed here, we recommend taking it to a professional for repair. With proper care and maintenance, your automatic wristwatch will last for many years to come.

Tools You Will Need

In order to repair your automatic wristwatch, you will need a few tools. First, you will need a small screwdriver. This will be used to remove the back of the watch so that you can access the movement. You will also need a watchmaker’s magnifying glass. This will help you to see the small parts inside the watch movement. Finally, you will need a soft cloth or a watch case opener. This will be used to clean the parts of the watch movement.

With these tools, you should be able to complete most repairs on your automatic wristwatch. However, if you are not comfortable working with small parts, you may want to take your watch to a professional watchmaker for repairs.

Opening the Watch

Your automatic wristwatch is a delicate timepiece, and as such, it needs to be handled with care. In this guide, we will show you how to open your watch so that you can access the inner workings and make any necessary repairs.

Before you begin, you will need a few tools: a small flat-head screwdriver, a small Phillips-head screwdriver, and a special watch opener tool. The watch opener tool is Used to open the case without damaging the crystal or case back. It is a cylindrical tool with two V-shaped notches cut into one end; the notches fit over the barrels of the watch case (the lugs) and allow you to twist the case open.

To begin, place the watch opener tool over the top of the watch case so that the V-shaped notches are lined up with the barrels (lugs). Holding the opener in place, twist it counterclockwise until the watch case pops open. If your watch has a screw-down crown (a knob on the side of the watch used to set the time), you will need to unscrew it before you can open the case. To do this, use your small Phillips-head screwdriver to loosen the crown until it comes free.

Once you have opened the case, you will be able to see all of the inner workings of your watch. To close the case, simply line up The barrel (lug) on one side of The Case With The Notch In The Holder And Push Down Firmly Until It Pops Into Place. Be sure that The Case Is Sealed Tightly Before Wearing Your Watch Again.

Replacing the Battery

Replacing the battery in your automatic wristwatch is a fairly simple process that you can do at home with a few household tools. You’ll need a small screwdriver, a new watch battery, and a steady hand. Once you have your materials gathered, follow these steps to replace the battery in your automatic wristwatch:

3. Replace the case back on your watch and screw it tight. Be careful not to overtighten the screw, as this could damage your watch.

Replacing the Stem

The stem is the part of the watch that you wind to set the time and date, and it also controls the stop/start/reset functions of the chronograph pushers. If your watch stops running or isn’t keeping accurate time, one problem may be a faulty stem. Although replacing a stem is a repair that you can do at home, it’s always best to take your watch to a qualified watchmaker or jeweler for service. Some watches have complications such as moonphase displays or perpetual calendars that require special tools and training to service, so it’s best to leave those types of repairs to the professionals.

Replacing the Crown

If your automatic wristwatch needs a new crown, you can replace it yourself with just a few tools. You’ll need a small screwdriver, a watch case wrench, and a new crown. Make sure you get the right size crown for your watch.

First, remove the old crown by unscrewing it from the watch case. Be careful not to strip the screw threads. Once the old crown is removed, screw in the new crown hand-tight.

Next, use the watch case wrench to unscrew the case back from the watch body. Be careful not to strip the screw threads here either. Once the case back is removed, you’ll be able to see the watch movement.

Once the new movement is in place, screw on the case back and tighten it with the watch case wrench. Then, screw on the new crown hand-tight and you’re done!

Closing the Watch

The next step is to place your thumb on the top of the watch and your first two fingers on the bottom. Apply pressure until you hear a clicking noise, which indicates that the watch is fully closed.
