Fratello’s Favorite Solar-Powered Watches Of 2025 — Including TAG Heuer, Tissot, And More

We mostly write about mechanical watches here on Fratello. However, we certainly get excited about the occasional solar-powered watches we see released. Solar-powered watches are ideal grab-and-go pieces. They are always running and often come in very capable configurations to withstand most everyday situations. It’s no wonder that big brands, such as TAG Heuer, Seiko, and Tissot, offer a range of options in this category. Let’s take a look at some of our favorite solar-powered watches of 2025.

It was quite a good year for these watches, actually. TAG Heuer introduced its solar-powered Formula 1 collection, Tissot launched its brand-new PRC 100, and Seiko brought us more limited-edition Speedtimer chronographs. Let’s dive in!

TAG Heuer Solargraphs for all

TAG Heuer offers many Aquaracer models featuring its Solargraph movement. My favorite is the 40mm titanium version. There was already one with a black dial featuring the distinctive horizontal lines. Then, this year, the brand also added an option with an ice-blue dial to the lineup. At €3,300, it’s one of the priciest watches on this list. However, with its lightweight case and bright dial, it’s a wonderful summer watch, especially because it charges while you’re lying on your towel next to the pool.

But TAG Heuer’s biggest solar-powered release this year was definitely its new Formula 1 Solargraph collection. The colorful 38mm re-editions of TAG Heuer’s Formula 1 got many of us excited, including me. The bead-blasted stainless steel cases come in a variety of configurations. Some are regular-production models, while others are limited editions that debuted during Formula 1 race weekends. They all cost €1,800–2,050 and are a lot of fun to wear, especially if you’re a fan of one of the world’s biggest sports.

Tissot PRC 100 Solar, aka the Lightmaster

Another big solar-powered watch release this year was Tissot’s PRC 100. This certainly isn’t the first solar-powered watch from Tissot. However, it does use the Swatch Group’s newly developed Lightmaster technology. This means the light isn’t captured by solar cells in the dial itself but by wafer-thin, hexagon-shaped solar panels in the watch’s sapphire crystal. This way, the dial texture and color aren’t limited to the capabilities of solar-panel technology.

Tissot launched the PRC 100 with a 39mm stainless steel model featuring either a blue or silver dial. There’s also a 39mm version with a black PVD-treated case and a black dial. Later on, Tissot introduced a 34mm version of the PRC 100 Solar. You can get that one with a stainless steel case and either a silver or ice-blue dial. There’s even an all-yellow-gold-PVD-coated variant and a steel and rose-tone one with a silver dial. Prices start at €445 for the PRC 100 Solar on a strap and increase to €595 for the yellow-gold-tone version on a bracelet.

Seiko SSC955 and SSC959 Speedtimer chronographs

Seiko always adds to the solar-powered fun, and this year, the Japanese brand certainly didn’t disappoint. The solar-powered Speedtimer chronographs are fan favorites, and Seiko added two limited-edition models to the collection in 2025. The SSC955 commemorates the World Athletics Championships Tokyo 25. The Games’ official color inspired its Edo purple dial, which looks nice combined with the darker purple sub-dials. The Speedtimer SSC955 is limited to 6,000 pieces and costs €770 if it’s still available.

However, my favorite new version is the SSC959 Speedtimer European Limited Edition. It features a cream dial paired with a steel bezel, and it looks incredibly cool. This one is limited to 3,000 pieces, costs €860, and comes with an additional brown leather strap.

If you’re looking for the pinnacle of solar-powered and GPS-connected watches, you probably know Seiko’s Astron collection. With the SSH187 and SSJ039, Seiko introduced two limited editions with galaxy-inspired dials. They both feature a titanium case and bracelet with a scratch-resistant black coating, cost €3,000 and €2,500, respectively, and are limited to 1,500 pieces each.

Casio G-Shock GW-BX5600-1 with a MIP display

If you’re into G-Shocks, you’re probably aware that the brand launched the DW-5000R-1A this year. It’s the closest re-edition to the original G-Shock DW-5000C from 1983, with a few minor updates. However, it doesn’t feature a solar-powered movement. If you’d like a solar-powered option that looks like the 1983 original, the new GW-BX5600-1 might be just the G-Shock for you. Apart from its classic looks, it also features a Memory-in-Pixel (MIP) display. This type of high-precision LCD offers higher contrast and a wider viewing angle for better readability.

If you’re very attached to your seven-segment digital display, the MIP display can show that. But if you’re not afraid of new things, you can also try the new font.

Did we miss anything?

So, there you have it — an overview of the Fratello team’s favorite solar-powered watch releases of 2025. My favorites are TAG Heuer’s funky Formula 1s and that summery Aquaracer.
