You'll be happy to learn that yes, solar watches are incredibly reliable and accurate. As they use solar cells to convert light into electrical energy - which will then provide power to the timepiece - solar watches eliminate the need for traditional batteries.

Just as the name indicates, the timepiece easily and automatically receives radio signals to precisely adjust the time and calendar functions.

First off, my stock response to this question when I get asked on Instagram is yes, the solar movement from Seiko, In my experience, has been very solid, accurate and dependable. It requires minimal maintenance and has a battery life of approximately ten years.

The Seiko Solar battery can last up to 10 years, depending on the model and usage. It is designed to be long-lasting and reliable, so you don't have to worry about replacing it often.

Seiko's Grand Seiko line, for example, is often considered a luxury watch brand, with prices ranging from several thousand to tens of thousands of dollars. Other Seiko watches, such as their more affordable Quartz and Solar lines, are not typically considered luxury watches.

This, coupled with wear throughout the year, has meant I've never come to them to find they have died. But of course, a battery, even a rechargeable one, does have a finite life span, and Seiko says this is around ten years. So ten years of worry-free accurate timekeeping is what you can expect from these movements.

10 years How long does the Seiko Solar battery last? The Seiko Solar battery can last up to 10 years, depending on the model and usage. It is designed to be long-lasting and reliable, so you don't have to worry about replacing it often.

However, Seiko is known for its strict quality control standards, regardless of where the watch is produced. So, while not all Seiko watches are made in Japan, they are all held to the same high standards of quality and craftsmanship that the brand is known for.

Most solar batteries have a lifespan of five to 15 years, but some can last 20 years. Keep in mind that these numbers are estimates. The reality boils down to the quality of the battery, as well as how closely you follow the manufacturer's recommendations for usage and maintenance.

Care of Your Watch As a solar watch requires no regular battery replacement, it may be worn for long time with perspiration and dirt left on the watch or band. Perspiration and dirt may lead to rust, etc. Please take care of your watch by wiping the watch and band with a soft cloth.

Rolex is a very good brand, it makes very good watches and you will very much enjoy wearing one, but I think a Grand Seiko just offers that bit more. You have to work for it, you have to explain it; you're way more likely to end up talking watches with someone wearing a Grand Seiko than you are a Rolex.
