A Seiko watch is a timepiece that can be relied upon to keep accurate time. But after years of use, the battery will eventually start to lose its power and you might have noticed your watch ticking more slowly or even stopping altogether. If this happens, it’s a good idea to replace the battery in order for your Seiko watch to perform as well as possible.

It might seem difficult at first glance but actually replacing the battery in a seiko submariner is surprisingly easy and should only take you a few minutes! In this article we’ll show you how-to does it step by step with pictures so there’s no reason not to get your old friend back on track again!

What Is A Seiko Watch And How Does It Work?

Seiko watches are electronic timepieces that display the time in the Japanese count of hours. A central seconds hand makes it easy for the wearer to monitor the seconds. The movement inside has an automatic winding system, powered by a rotor (a weighted wheel which oscillates when rotated) at the back of the watch. The rotor’s motion is transmitted through gears to turn the hands on their axes at one rotation per minute.

Why Do I Need To Replace My Old Battery?

The battery in your Seiko watch can wear out over time, or simply when exposed to high temperatures. You’ll notice that after being exposed to heat or cold, your watch will start working again which means the battery has gone bad.

How Do I Change My Old Battery?

Replacing the battery is actually surprisingly easy, but please takes note of precautions before you begin! You’ll need a small screwdriver to open up your watch back and obtain access to where you can replace your old battery.

Step 1: open the watch case

Use your small screwdriver to gently unclip the back of your Seiko watch, revealing where you can replace the battery. Once inside, take note of which way is up so that it’s easier for you to put on the new battery properly when you’re done.

Step 2: remove the old battery

Make sure you don’t drop the spring bars; they are pretty small and could be lost easily. Instead of dropping them, lay out a piece of paper or plastic with “Seiko” written on it, then place the watch face down (upside down) to prevent anything from falling out; this way, the spring bars will be on top of your “Seiko” paper. Remove the old battery with your fingers by lifting it straight up.

Step 3: put in the new battery

Once you have removed the old battery, it’s time to replace it. You can use either AAA or AA batteries for your Seiko watch, as long as they are the same size. Put in the new battery with the plus sign facing up (in other words, make sure that you put it in correctly). You can either close up your Seiko watch now, or check to see whether it works if you’d like to do more experiments.

Step 4: enjoy your watch!

After you have closed up your Seiko watch, try winding it so that it can start working again. Once this is done, you can put the watch back on and continue to use it for many years to come!
