How To Charge Seiko Solar Watch? [Isn’t Daily Exposure to Sunlight Enough?]

Light powers Seiko solar watches batteries. Under the dial is a solar cell that transforms sunlight into electrical energy, which powers the watch. The amount of energy the battery can store varies by model, although, typically, it can function for several months without being exposed to light. But how to charge Seiko solar watch? Should you just expose it to direct sunlight?

To recharge your Seiko watch, you must expose it to light. Indoor light is weaker than direct sunshine, so it takes much longer to recharge the watch. Set the watch near a window and expose it to sunshine, with the dial towards the sun.

When charging the watch by keeping it exposed to sun rays, make sure it doesn’t get heated too much.

Recharging will not take place if the light is insufficient or if the solar watch is not exposed to enough light for an extended period.

If the amount of light and time you expose your watch to light is insufficient, you will not receive as much recharging as you like.

A rechargeable battery is more environmentally friendly than disposable batteries, such as dry batteries and button batteries.

It can be recharged and discharged many times before the battery stops functioning.

To recharge a solar watch, you must expose it to light. Because interior lighting is less powerful than sunshine, it takes longer to recharge the watch.

When charging the watch, place it near a window and sun it with the dial facing the sun.

Place the watch near a window and expose it to sunlight while charging it, with the dial facing the sun.

When charging the watch near the window, make sure it is not in direct sunlight through the glass, as it will heat the watch to high temperatures.

In the dark, a solar watch cannot be charged.

The following events are likely to cause the watch’s energy to run out, causing it to stop.

You tuck the watch into your sleeve.
You are not wearing your watch or keeping it in an area with insufficient light for an extended period.

The watch’s battery does not have enough power to be worn on the wrist. When you are not wearing it, place it near a window and let it soak up some sunlight.

How Long Does It Take To Charge A Solar Watch?

Although we recommend charging your solar watch under direct sunshine, solar watches can also absorb artificial light.

However, artificial light is not as effective as natural light.

Should You Service Your Seiko Solar Watch?

The capacity or recharge efficiency of a rechargeable battery may gradually decline due to a variety of factors such as long-term usage or usage conditions.

Mechanical parts that are worn or dirty, oils, and batteries can all reduce recharging cycles.

We recommend getting your solar watch maintained (overhauled) every three or four years to ensure that it functions correctly and that you can use it for a long period.

A watch overhaul is like a physical examination of a wristwatch.
It is vital to inspect the inside of the watch for oil retention, overly tight screws, rust from dirt and sweat, and other concerns.

During an overhaul, you will remove dirt and perspiration from an invisible zone, ensuring that functions and water resistance continue to work as smoothly as a new timepiece.

Seiko clocks will last for a long time, with little maintenance.

A watch, like any precise piece of equipment, must be serviced regularly to ensure that it operates flawlessly.

Why Do You Need to Service a Solar Seiko Watch?

Worn-out movement parts and old oil within the machine can cause a watch to lose time or stop working.

As a result, our technical experts will inspect the timepiece for any broken components that require replacement or repair, and the disassembled components will be cleaned and lubricated once more.

When Should a Seiko Solar Watch Battery Be Replaced?

Solar-powered clocks have the advantage of charging almost constantly, so they only consume the battery reserve when there is no light source.

However, there are a few things to keep in mind about the watches’ proclivity to be constantly charged.

To begin with, repeated recharges will ruin the watch’s battery – just like any rechargeable battery, it can only withstand so many recharges before the battery life begins to degrade.

Second, Seiko suggests replacing the battery every ten years to ensure peak performance.

Remember that if properly cared for, Seiko watches can last for over ten years.

Some solar watches feature a backup battery, and according to testing, a backup battery can keep up to 80% of its storage capacity after 20 years.

So, while your battery will need to be replaced after ten years, your watch may last much longer.

However, we must advise you not to charge your solar watch in direct sunlight or leave it on the dashboard of a vehicle, as the temperature of the watch might increase to dangerous levels, resulting in a malfunction.

The most respected companies provide high-quality watches that will last a long time. It also suggests that you will receive a manufacturer’s guarantee, which will provide you peace of mind if anything goes wrong.

Light is used to power the movements in solar-powered Seiko clocks. Under the dial, a solar cell transforms sunlight into electrical energy, which is then used to power the watch.

We recommend getting your watch serviced at an approved Seiko Service Center every three years.

Are Solar-powered Watches Reliable?

Solar-powered watches are unquestionably useful. They are getting more popular by the year as people learn the many advantages of using solar electricity. Here are just a handful of the advantages:

  • Solar energy is a renewable resource that does not emit pollutants or contaminate the air, water, or soil.
  • It is cost-effective: it produces electricity with minimal waste.
  • Solar energy has many applications, including powering homes and businesses, delivering hot water, and even generating electricity.

So, if you want to power your home or business in an environmentally friendly and effective manner, solar power is an excellent choice.

Final Thoughts

Seiko watches are famous for their durability, making them an excellent choice for those searching for a long-lasting watch.

Light powers Seiko Solar watches. A solar cell beneath the dial converts sunlight into electrical energy, which powers the watch.

Therefore, you must expose your Seiko watch to light to recharge it.

Because indoor light is weaker than direct sunlight, charging the watch under artificial light takes much longer.

Place the watch near a window and expose it to sunlight, the dial facing the sun. When charging the watch by leaving it out in the sun, take care not to overheat it.
