How long do Seiko solar watches last?

The answer to this question varies greatly.

Some Seiko solar watches, such as the SEIKO 5 Sports models and the SKX007, can last for more than 12 years without ever needing to replace a battery.

Other Seiko solar watches may only be expected to last up to 3-4 years before requiring a new battery.

Factors that can affect the lifespan of a Seiko solar watch

As with any watch, there are a number of factors that can affect the lifespan of a Seiko solar watch. Here are some of the most important ones to keep in mind:

  • The battery: One of the most important parts of a solar watch is the battery. If the battery dies, the watch will no longer work. Seiko solar watches use high-quality batteries that should last for several years, but it is still important to keep an eye on the battery life and replace it when necessary.
  • The solar panel: The solar panel is what charges the battery in a solar watch. If the panel becomes damaged or dirty, it will not be able to charge the battery properly and the watch will eventually die. Keep the solar panel clean and free of dirt and debris to ensure optimal performance.
  • The seals: All watches, including Seiko solar watches, have seals that keep water and dust out. Over time, these seals can degrade and allow water and dust to enter the watch, which can damage the internals. Inspect the seals regularly and replace them if necessary.
  • The movement: The movement is the heart of a watch, and it is what keeps time. Seiko solar watches use high-quality quartz movements that are built to last, but they can still be damaged by shock or wear and tear. Be careful with your watch and have it serviced regularly to ensure the movement stays in good condition.
  • The crystal: The crystal is the clear cover that protects the dial of a watch. It can be made from a variety of materials, but Seiko solar watches typically use mineral crystals. Over time, these crystals can scratch or crack, so it is important to handle them with care. If the crystal becomes damaged, it can be replaced.

By taking care of your Seiko solar watch and keeping an eye on these key components, you can ensure that your watch will last for many years to come.

Other factors that affect the lifespan of a Seiko solar watch

The amount of time exposed to light is another factor that can affect the lifespan of a Seiko solar watch.

The longer the exposure to light, the more energy is drawn from the battery.

As well, exposure to humidity can also have an effect on how long a solar watch will last.

These are just some of the ways in which you can increase your chances of getting maximum performance out of your solar watch.

If you want to make sure that your solar watch lasts as long as possible, you should also avoid using the provided CR2016 battery until it dies.

Solar watches without a battery will continue to generate power from light even after being exposed to sunlight for a prolonged period of time.

However, if an old dead CR2016 is inserted into a solar watch, it can significantly reduce the expected lifespan of a watch.

Another factor that may affect the performance of a solar watch is its exposure to very low temperatures.

This is because the low temperature will greatly alter the efficiency with which light energy converts into electric energy.

As such, if your solar-powered watch was exposed to extremely cold weather (such as a burst of freezing rain) or if it is heated to extremely high temperatures, it may affect the expected lifespan of a solar watch.

Tips for prolonging the life of your Seiko solar watch

Some shot tips to help you get maximum performance from your solar watch include:

– Keep your solar watch away from extreme light (ultraviolet and direct sunlight).

– Make sure that your solar watch is never exposed to humidity.

– Avoid using the CR2016 battery included with the watch; instead, use a standard 1.5V silver oxide battery (SR43SW) to avoid shortening the expected lifespan of your watch.

– Try not to expose your solar watch to low temperatures or extremely high temperatures.

– Don’t wear your watch in dusty conditions, which can lead to premature battery damage.

What is the warranty on a Seiko solar watch?

Standard solar watches are warranted by Seiko for 1 year worldwide, from 2 to 3 years in the US only from the date of purchase.

This means that you can have your entire watch repaired or replaced if something goes wrong with it within the time from the date of purchase; however, there are usually many conditions included in this warranty, such as:

– If your watch isn’t performing as it should, you must provide proof of purchase (a receipt) to make sure that the watch was purchased from an authorized dealer.

if there’s no proof of purchase and you cannot prove that the faulty watch is under warranty, you will not be able to claim a repair or replacement. (Source)

– If you have had the watch for more than 2 years, Seiko may charge you a processing fee to fix your watch or replace it.

– This warranty does not cover damage, failure, loss of function due to battery failure if the user has failed to provide proper care and maintenance according to Seiko’s guidelines (i.e.

worn it in dusty or humid conditions).

– If you prefer, Seiko will repair any solar watch for $60 USD instead of replacing it.

However, this fee does not include the cost of returning the watch to the dealer and Seiko will not pay for shipping.

Are Seiko solar-powered watches any good?

The answer to this question will depend on your perspective.

There is some criticism that Seiko watches tend to be large, bulky, and unattractive.

However, many Seiko solar watches are very stylish and can fit in with a casual outfit or a pair of dress clothes.

Solar-powered watches from other manufacturers usually have a larger battery that protrudes out of the watch and can become scratched or damaged over time. (Source)

Seiko solar watches typically have soft leather bands which do not crack or warp as easily as other types of material.

Therefore, if you are looking for a stylish, functional, and averagely priced solar-powered watch, then a Seiko may be an ideal choice for you.

If you care more about fashion than functionality, then you may want to consider looking for a more modern-looking solar watch.

Are solar watches worth it?

Quick answer: it depends on your preferences.

To determine whether a solar watch is for you, ask yourself the following questions:

– How often do you travel? If you are planning to be away from electrical sockets for extended periods of time, then it would make sense to choose a solar-powered watch since it can last up to 6 months on one charge.

– How often do you go outside? If you spend most of your time indoors and only venture outside occasionally, then a solar watch will probably not be very useful to you since it may not receive enough light to keep the battery fully charged.

– Do you prefer fashion over function? If so, consider looking at other types of watches as they may be more fashionable and may last longer. (Source)

– How expensive do you want your watch to be? It is worth noting that some solar watches can cost upwards of $300 USD, which is significantly higher than the average silver oxide battery-powered watch (which costs about $20 USD-$25 USD).

Why did my Seiko solar watch stop?

If your watch has stopped because the battery is empty, it may be that your solar watch did not receive enough light or that the battery wasn’t able to recharge fully before you used the watch again.

Further causes for this could include:

– The watch was exposed to light that had too much ultraviolet.

– The battery is defective, malfunctioning, or damaged.

– There’s water inside the watch.

If you have worn your solar watch in the rain or taken a shower with it on, then there may be water trapped inside which can short circuit the electronic system and cause damage.

– The battery terminals (the metal pieces on the watch face where you connect your watch to a power source) are dirty or corroded.

Cleaning them will allow for better contact with the adapter and can fix this problem.

As mentioned previously, if there’s no proof of purchase then Seiko may charge you for repairing your solar-powered watch.

What kind of battery does a Seiko solar watch take?

Seiko solar-powered watches can take two kinds of batteries:

– Seiko’s own rechargeable battery SR927SW – is a silver oxide battery, which can last up to 6 months on one charge.

Silver oxide batteries are found in most Seiko solar-powered watches and usually have a longer life than lithium-ion or NiMH batteries.

– Seiko’s proprietary lithium-ion/polymer long-life battery L043 – is a rechargeable, more powerful, and a longer-lasting battery that can usually last up to 2 years on one charge.

These watches are typically more expensive than silver oxide-powered watches, but they have a longer life span and need less frequent charging.

They range from about $100 USD to upwards of $200 USD.


Seiko solar watches are a popular choice for those looking for an affordable and long-lasting timepiece.

While the lifespan of each watch varies depending on use, it’s generally estimated that it will last around 10 years.

Keep your Seiko solar watch in good condition and it will continue to keep accurate time for many years to come.
