Automatic Watch Running Too Fast Or Too Slow? (Simple Answers)

We all know that watches, especially automatic ones, can run a little fast or slow every now and then.

If your watch has been ticking along just fine for years but all of the sudden started running too quickly (or slowly), you may be wondering what’s going on.

Here are some simple answers to help get your timepiece back on track.

Keep reading for tips on how to adjust your automatic watch’s time.

Automatic watch running too fast or too slow?

Even if we have had excellent watches for a long time, Excellent Automatic Watches have not existed.

This is a watch that can store energy and run without the help of any battery or additional power source just by the natural movement of your wrist.

Some users may see the indicator on their Automatic Watch slightly differently from the standard time.

Different automatic watches, when worn on one person may also be slightly different from another.

They are often + – 10 seconds per day from normal time, so changes in them can be quite difficult to notice.

The Automatic Clock is known to run too fast or run too slow when it runs for more than + – 30 seconds a day.

An automatic watch that runs too fast or too slow can be caused by the user wearing it too heavily, being worn loosely, or it’s too old, etc.

The running time of the Automatic Watches will vary depending on the weather and their movements.

If your Automatic Watch runs too fast or runs too slow for more than 24 hours, try taking it to a watchmaker and they will check and repair it for you.

So what should we do when it runs too fast or slow?

What I suggest is to make a simple movement test by following the steps below:

  • Make sure you have a winder. Put the test watch in a winder for a day and check it again.

If it stops running, means your automatic watch needs service because of something wrong with its movement.

  • If it still keeps running, try to do the movement test by using the crown.

What you need to do is wind hand-by-hand and let the watch passes one complete day cycle (24 hours) and check it again.

Now, let’s learn more about their fast and slowness of them through questions from the user community.

Do automatic watches run fast when new?

When you first get an automatic watch, it might run too fast or too slow.

But don’t worry, this is normal.

To help the watch start keeping good time, you need to wind the mainspring.

This can be done with a winder or by shaking and wearing the watch continuously. (Source)

How do you speed up or slow down an automatic watch?

Automatic watches work by gravity, so you can make them run faster or slower by moving them to different positions.

If your watch is running slow, try it by keeping it on its side with the crown facing up when not wearing it.

How do I make my automatic watch more accurate?

One way to improve the accuracy of a mechanical watch is to wind it up at the same time every day.

This will ensure that the watch has enough energy to run properly. (Source)

Is it normal for an automatic watch to run slow?

When fully wound automatic watches will continue to run for about 36 hours after they are removed.

If the watch is still running slowly after being wound it may need service.

Why is my automatic watch running fast?

If the clock is running too fast, it may be because the hairsprings have become magnetized.

This happens when the coils are stuck together.

Magnetism can also cause your watch to stop or slow down, but usually, it will just make the watch go fast. (Source)

How long does it take for an automatic watch to settle down?

Most people find that the average automatic watch takes around 40-50 hours to “stabilize”.

This means that the watch will work fine and the time will be accurate.

Some of them last longer than this, but it is a few.

If you wear the watch daily, you only need about 30 hours of energy stored in it.

Why are automatic watches inaccurate?

The metal in a mechanical watch can change size due to the rise and fall of temperature.

So the temperature affects the accuracy of the watch.

In fact, watches lose time when it’s hot and increase the time when it’s cold. (Source)

Can you adjust an automatic watch?

If you keep your automatic watch wound up or wear it every day, you won’t have to set it up as often.

However, automatic watches need to be set periodically, usually once a month for watches with a date window. (Source)

How much time does an automatic watch lose per day?

Yes, a mechanical clock is usually 5 to 10 seconds slow or fast.

This is because they are all self-winding in the course of each person’s use and each watch is different.

Do magnets affect automatic watches?

Magnets can have an effect on automatic watches.

This means that the watch might not be as accurate after being around a magnet.

If you want to improve the accuracy, you should have it demagnetized. (Source)

Should I wind my automatic watch every day?

It is okay to wind your automatic watch every once in a while, but not often.

This is especially important if your watch has a crown.

If you do wind it too often, it will wear down the power reserve.

However, it will automatically wind itself every time you move (due to the oscillating weight). (Source)

How often should I wind the automatic watch?

If you wear your watch all the time and sit at work all day, you will need to wind it regularly.

Since you sit still, the movement of the wristband will move less than enough for the watch to be powered.

Towards the end of the day, you will notice that it runs out of power.

So we recommend rewinding it 30 to 40 turns before wearing it again. (Source)


If you’re noticing that your watch is running either too quickly or slowly, don’t worry – there are simple solutions to solving the problem!

Whether it’s a matter of getting your watch serviced by a professional or making a few small adjustments yourself.

We hope this article has given you the tools you need to get your automatic timepiece back on track.
