Did someone give you a Seiko solar timepiece with a different time setting? You can recalibrate this timepiece if you know how to reset Seiko solar watch. Resetting Seiko chronograph is not a complicated process, although there are sequential steps you must follow.

You can also adhere to these steps if your Seiko solar chronograph stopped working. Doing so lets you enjoy the wristwatch’s superb timekeeping accuracy and exceptional longevity.

I will teach you how to reset your Seiko solar watch, and maybe you can teach others, too.


Things You Need for This Tutorial


Resetting a Seiko solar watch is not as complicated as some people think. However, I recommend checking out the following things before resetting your watch.

Owner’s Manual

First, I advise you to check your Seiko owner’s manual or product information. It has everything you need about recalibrating your timepiece, including the different buttons or knobs to manipulate.

You can also search online for downloadable manuals if you do not have any.

Adjustment Mechanisms

Second, it would be wise to check your Seiko solar watch’s adjustment mechanisms. For example, a broken knob or defective button will make it challenging to adjust the time and other wristwatch parameters.

Charge Status

Third, recharge your Seiko solar light before recalibration. Resetting the wristwatch without sufficient power will make your efforts for naught. After all, charging your solar watch does not take long.

Moreover, check if your Seiko solar watch is charging as it should. Seiko solar chronographs achieve a full-charge status within three hours on sunny days and ten hours on cloudy days.

It also makes sense to have a professional assess your chronograph before resetting if you notice your watch takes a longer time to charge than it should.

Indicator Status

Fourth, if you notice your Seiko solar watch not working, it may be wise to bring it to an authorized service center. Problems with the wristwatch’s capacitor can lead to indicator malfunction. Resetting it will be useless because your watch will not adjust to the desired parameters.

Steps for Resetting a Seiko Solar Watch


Step 1: Pull the Seiko solar watch’s crown to the reset mode.

Mechanical watches always have knobs on the watch case’s right side. The central knob (called the crown) is at the 3 o’clock position.

You might also see smaller buttons at the 2 o’clock and 4 o’clock positions. These parts are the Seiko solar watch’s pushers, allowing you to activate a particular time indicator for adjustment.

The first step requires you to pull the Seiko solar chronograph’s crown, stopping the wristwatch and allowing you to make the necessary adjustments.

The first click you hear indicates the date adjuster mechanism, enabling you to adjust the Day and Date in the watch’s date window.

Pull the crown again, and you should hear a second click. Doing this step lets you adjust the time.

Pro Tip: I recommend reading your Seiko X Solar watch’s manual for the controls. Some models may have the buttons in different locations around the watch’s case.

Step 2: Press and hold the A button to adjust each indicator.

The Seiko solar watch’s upper adjustment pusher or button serves as an indicator selector. If your Seiko solar watch only has one pusher, you can expect the pusher to perform all the resetting or time adjustments.

However, if your watch has a lower pusher, the A button serves as a mode selector. The B (lower) button acts as an indicator adjuster.

To reset Seiko chronograph, press the upper pusher and hold it for two seconds. Check which watch indicator moves because it signifies the parameter you can adjust.

You can release the A button and press and hold it again for two seconds if you wish to activate a different indicator.

Step 3: Press and hold the B button to modify the watch’s hour and minute hands.

As mentioned, the B button in some Seiko solar chronographs adjusts the chosen indicator. There are two ways you can modify the time settings or other watch parameters.

First, pressing and holding the B pusher will rotate the hands towards the 12 o’clock or the 60th-minute position.

Second, pressing the lower button once at a time lets you adjust the settings more accurately.

Everything depends on what you want to adjust. Most horologists recommend using the second method to ensure accuracy.

Step 4: Perform Steps 2 and 3 for the other indicators.

Seiko solar chronographs come with different designs, including sub-dials (miniature clocks on the wristwatch’s main dial. These sub-dials are at the 12 o’clock, 9 o’clock, and 6 o’clock positions. Some models might have these mini clocks at the 3 o’clock, 6 o’clock, and 9 o’clock positions.

Most Seiko models adjust the Stopwatch sub-dial first, at the 12’o clock position. The 1/20 seconds sub-dial comes next, followed by the watch’s main second hand. The Stopwatch’s time hands are the last settings you can adjust.

Some Seiko models have a different sub-dial design. Hence, it would be best to check your manual again.

When resetting these indicators, always start by pressing and holding the upper pusher (A button) before making the adjustment with the lower pusher (B button).

Step 5: Finish the watch resetting.

You can push the Seiko solar watch’s crown (central knob) back into its place once you are happy with the new time settings. Check for movement of the second hand, indicating normal operation.

Learning how to reset Seiko solar watch is as plain and simple as pulling the crown and pressing the appropriate pushers to modify the time settings.
