How to open the back cover of a wristwatch. How to change the battery in a wristwatch? Video: replacing batteries in a wristwatch

This type of wristwatch, such as quartz, is the most common modification. They are worn by both old and young.

These watches have a fairly high power reserve, even despite the cheapness of most models. The only thing that is necessary for their periodic maintenance is replacing the battery. I have already talked about how to change the mechanism.

The replacement is quite simple, and, in principle, does not require any special skills or tools. The main thing is accuracy. After all, the mechanism of a wristwatch is very fragile and rough handling can damage it forever.

There are two main types of cover fastening on quartz wristwatches - latch and screw. If the back cover is not round in shape (rectangular, square, oval), then the type of fastening is only a latch.

If the lid is round, you need to look at it more closely - there are special recesses on the screws for unscrewing (1 photo right watch), on the latches, as a rule, there are none (1 photo left watch), although there are exceptions - latches with recesses for screwing "

Japanese quartz or Swiss mechanics? This question has been haunting the minds of millions of future watch owners for several years. Undoubtedly, with the advent of the Apple Watch and smart wearable devices from third-party developers, sales of classic wristwatches have decreased noticeably, as Swiss manufacturers have already reported more than once. Both smart devices and multifunctional quartz are “dependent” on electricity, or more precisely on a small power supply. But if “smart” devices need to be charged almost every day, then a regular battery in a wristwatch lasts for a couple of years. We will tell you in this article how to change the battery in a wristwatch without affecting the functionality of the device.

Sooner or later, every quartz owner will think about the above question, since in our world nothing lasts forever. Of course, you can go to a watch shop, but it’s much easier to buy a battery in a store and replace it yourself at home. When purchasing, you should not save, as a low-quality battery can damage the watch mechanism. A high-quality power supply, as a rule, ensures the operation of a wristwatch for 2-5 years.

To replace the power supply in a watch, you must first remove the back cover. Typically, there are several ways to attach the cover to the body. It can be either pressed or tightened using small screws. If there are screws at the edges of the cover, unscrew them using a small clock screwdriver with the appropriate profile. Moreover, when unscrewing, do not rush, because the screws are quite fragile. If there are no screws on the back cover, then find a small recess, pick it up with a screwdriver or knife and pry off the cover.

However, there are watches with a fastening in the form of a threaded ring. In this case, there are small notches in a circle on the back cover. As a rule, such covers are unscrewed to the left.

Replacing a watch battery will not cause any difficulties if you use the tools skillfully. After opening the back cover, carefully inspect the internal mechanics, note the location of the battery and its polarity, and then carefully remove the power element using non-metallic tweezers. It is important that the new battery matches the element being replaced in all respects (diameter, thickness, voltage), otherwise the watch may lose its functionality.

After installing the power supply, make sure the watch is working properly and carefully screw or press in the cover. At the same time, try not to touch the battery with your fingers. If the back of your watch is marked "Water Resistant", be careful not to damage the seal when closing the cover.

The new generation of quartz uses “End Of Life” technology. The low battery indicator (EOL) is activated when the battery is running low. If on a watch equipped with an EOL system, the second hand stops jumping every second and starts counting down 4 seconds, then this indicates that it is time to change the battery on the watch.

A video on how to change the battery on a wristwatch is available below:

A wristwatch is not only an object that tells the time. It is also a fashion accessory that emphasizes the impeccable style of its owner.

There are watches that operate from a voltage source or have a winding mechanism. Battery-powered watches are more convenient because they do not need to be wound regularly. As a rule, the battery in such watches lasts for a long time. If the watch suddenly begins to show the time incorrectly or stops, then it is time to replace the battery in it.

As a rule, it costs very little, but you will have to pay a considerable amount for the work to replace it. To save money, you can try to do it yourself.

How to replace the battery in a wristwatch with your own hands

The difficulty of this work lies in the fact that the watch has a complex mechanism that can be damaged during the process of replacing the battery. In addition, you need to open the watch very carefully so as not to spoil its appearance. Another important parameter is the battery voltage; it must meet the requirements of the watch manufacturer.

Before you start replacing the watch battery, you need to:

  • make sure that the cause of the malfunction is a dead battery. Some models of electronic watches have a special indicator that shows the battery charge level. If it is missing, diagnostics can be carried out using a special device that measures current strength;
  • make sure that the battery that will be inserted into the watch is suitable in size and voltage level for this model;
  • Make sure the battery is of proper quality. Good batteries ensure uninterrupted operation of the watch for a period of 2 to 5 years.

To replace the battery in a wristwatch, follow the following instructions.

  1. First you need to open the watch case. Its back cover can be attached with screws or pressed on. In the first case, you should use a screwdriver of the appropriate size. In the second case, the lid should have a small recess that allows you to pick it up with a knife or other similar tool. In this case, you need to act very carefully so as not to damage the watch case or injure your hands. There is another option for attaching the lid - it can be screwed on. In this case, in order to unscrew it, you will have to use a caliper.
  2. After removing the cover, you need to remove the battery using tweezers. Before doing this, you must remember or photograph its position in order to correctly install the new battery. Do not remove the battery by hand or with metal tweezers, as this may negatively affect its properties. Plastic tweezers work best.
  3. Then you need to insert a new battery. You should also not take it with your hands. This must be done with the same tweezers. The polarity of the battery must be observed. The battery must be held firmly in the place provided for it and not dangle. After the battery is installed, you need to make sure that the clock is running. Only then can the housing cover be replaced.
  4. Before replacing the watch cover, you need to check the gasket. If it is worn out, you need to lubricate the surface with sealant. If the lid has been unscrewed, it screws back in the opposite direction.

If the lid was pressed, you need to press it on top with a small flat object, preferably wooden. After this, it should snap into place without difficulty. Before closing the lid, you need to place the watch on a soft cloth with the dial facing down and make sure that the hand position adjustment wheel matches the corresponding groove on the lid.

The given instructions for replacing the battery in a wristwatch are generalized. Different models may have their own characteristics for replacing the battery. Before you begin, be sure to read the watch's instruction manual.

When replacing the battery, you need to act very carefully so as not to damage the small mechanisms of the watch, as this can lead to their failure and the need for expensive repairs.

Be sure to make sure that the battery inserted into the watch meets its dimensions and the manufacturer's requirements.

If you follow all the requirements and instructions during operation, replacing the watch battery will not take much time. At the same time, you can significantly save money and time on going to the workshop.

There is a simple rule: “if your watch breaks, take it to the workshop.” However, there are times when you just need to replace the battery. This is easy to do with your own hands if you open the back cover of the watch. So we'll look at how this can be done.

In inexpensive watches, the lid is made with a latch. There are two versions of the latch - with a boss on the lid and with a groove on the lid and watch case. In the first case, use a flat-head screwdriver of a suitable size to pry up the tongue of the lid, and pressing the screwdriver against the body, open the lid. In the second case, we use a sharp, durable blade such as a scalpel or shoe knife. We insert a sharpened blade into the groove and forcefully remove the lid from the lock. There are covers with fastening in the form of a threaded ring. It is advisable to have a special tool here. But a regular caliper also works well. We spread the outer jaws of the caliper so that they fit tightly into the grooves of the fastening ring, and fix them with a locking screw in this position. Then carefully unscrew the locking ring by slowly rotating the caliper counterclockwise. Then we pry up the cover with a clock screwdriver and remove it from the case. There are covers simply with threaded fastening. The thread is cut directly onto the side edge of the lid. The opening method is similar to that specified in paragraph 2, with the exception of using not external, but internal jaws of the caliper. Well, the last method is to screw the lid. Fastening is made using miniature bolts. It is necessary to unscrew the bolts only using a high-quality watch screwdriver with the appropriate profile. Otherwise, there is a chance of damaging the screw splines, and further removal will be quite difficult. Here it will be impossible to do without a master. We remember that it is necessary to unscrew the screws in a certain sequence, diagonally.


Well, that's all. Don't forget that under any lid there is a seal. Carry out all work carefully so as not to damage it. Otherwise, the sealing of the watch mechanism will be broken and its lifespan will be sharply reduced.

A modern person rarely has to worry about the problem of replacing a battery in a wristwatch. Usually they are changed at points of sale quickly and free of charge. But sellers are different. It happens that behind the counter you are greeted by a charming young lady who may understand the sizes and manufacturers of batteries, but has no idea how to design a wrist accessory. This problem is also familiar to those who go on long hikes or whose work involves constant exposure to nature. A watch is irreplaceable, and a spare battery should always be in your pocket.

Variety of batteries for watches

Pocket and wrist watches – the time of quartz devices

Mechanical watches – prestige and status. And often also the memory of those beloved relatives to whom they belonged. Modern quartz watches are certainly an elegant accessory, but also a necessity to constantly be in the flow of time and monitor it. Winding a mechanical watch is a beautiful procedure, a kind of ritual. Replacing the battery in a wristwatch is an important routine. Let's find out what is needed for this.

What will you need to open and remove the cover? Determining the type of protection

So, let’s say that you have a bloody nose and need to insert the battery into your watch yourself - the mechanism is standing, the time-measuring device will soon come in handy, there is a spare battery. In a good watch, the battery and mechanism are reliably protected by a cover that can be attached in at least three ways:

  • screwed on with screws;
  • closed with a screw mechanism;
  • closed with a slamming mechanism.

These methods determine how to correctly and accurately remove the cover of a wrist or pocket watch without damaging your valuable device and precious nerves.

Pocket and wristwatch cover – reliable protection

Method No. 1. How to open a watch with a snap cover using your fingernail?

Changing the battery in a quartz wristwatch with this type of cover is not difficult. Look carefully at the back of your accessory and feel for something like a notch or indentation. Then pick up this place with your fingernail and pull the watch cover towards you. The threat of ruining your manicure undoubtedly exists.

If you have small scissors, a knife or something similar that is flat and hard on hand, use it

And leave damage to your nails to a completely hopeless situation. Be careful if the back of your watch just won't open, no matter how hard you try. Stop damaging property. You may be dealing with a screw cap.

Method No. 2. How to unscrew a screw-down back cover with a rubber ball?

Ideally, you should have a caliper handy for this type of cap. It's better to use it like this:

  1. Spread the tool along the width of the marks and tighten the bolt firmly.
  2. Insert the caliper into the two recesses and smoothly begin to unscrew the cover to the left.

But a caliper is not always an accessible tool. It’s still somehow easier to find a rubber ball. To do this, firmly press the watch cover without a recess with a rubber ball (little by little!) to ensure its reliable adhesion to the surface.

Keep the watch in one place and rotate the ball counterclockwise without lifting it from the lid. As the ball turns, the defense must also move. If everything works out, then carefully unscrew the cap all the way with your fingertips.

  1. Open the scissors.
  2. Install their tips into two opposite grooves in the cover.
  3. Secure with a little force and begin turning the scissors counterclockwise.
  4. Has the lid given way? Unscrew it all the way with your fingers.

And please be very, very careful with scissors! Do not accidentally injure yourself or others.

Vernier calipers are a safe tool for opening the watch cover.

Method No. 3. How to unscrew a tight back cover or a cover with screws?

You can open the watch to change the battery with your fingernail only if a couple of conditions are met:

  1. The nail is quite strong and long.
  2. The screws are not tightened too tightly.

But for a more successful result, it is more convenient to use scissors, a knife or a screwdriver of the appropriate size. Simply place one tip of the tool into the groove on the head of one of the screws. Be sure to press the end of the tool firmly into the grooves and do not lose your grip as you turn them. Unscrew all the screws one by one and carefully place them in one place. They are small and instantly lost.

Changing the battery

Hooray! The cover is off! The battery is in front of us. What's next? And then, to successfully change the battery in a quartz wristwatch without damaging it, use tweezers or small tweezers. Use them to remove the old battery, but first remember its correct location in the watch. Confusing a plus with a minus is a questionable procedure for a fragile device.

If the size and shape of the new battery completely matches the old one, also carefully insert it into place in the watch using pliers or tweezers, observing the polarity

Check the clock operation. Are they coming? Wonderful! No? Check again the contact of the battery in the mechanism and, if possible, its expiration date. If everything is ok, but the clock still does not work, then contact a specialist. The risk of the watch breaking is high.

Carefully replacing the battery with tweezers

Put the cover in place

In any case, you should still close the back cover of the watch after replacing or removing the battery. If you find something to unscrew the protection with, use the same thing to screw it back. Only with a rubber ball, do everything in the reverse order - first, carefully screw it in with your fingers, and then press the ball and screw it all the way. Don't overdo it! Simply press the slamming lid firmly with the right side, most often until it clicks lightly.

These are the simple tricks for replacing batteries. Don’t forget to set the hands on the dial to the correct time and get ready to answer the simple question “What time is it?” for another couple of years. Can you tell me?" And this watch will help you with this:
