Ten minutes of sunlight is enough to power the new TAG Heuer Aquaracer Professional 200 Solargraph for forty hours. The watch, part of a new 2026 collection from the Swiss brand, houses the TH50-00 movement, which converts natural and artificial light into reliable energy. It’s a practical technology at the heart of a collection that traces its origins to 1978.
That year, Jack Heuer introduced the Heuer Reference 844, a watch designed for resilience in water. The Aquaracer name became official in 2004, built around six functional principles: a unidirectional rotating bezel, a screw-down crown, water resistance of at least 200 meters, luminous markings, a sapphire crystal, and a double safety clasp. The latest Solargraph models continue this legacy.
The Reimagined Tool Watch
The second expression is a reimagined 40 mm Aquaracer Professional 200 Solargraph. Here, the focus is on technical details and materials. The case geometry is sharper, the bezel is newly sculpted with reintroduced rider elements, and the case features a fluted shape at 9 o’clock. The bracelet is now interchangeable, adding to its versatility.
This larger model is available in four distinct versions. Two are crafted from steel, with deep blue or vibrant green dials marked by defining horizontal lines. A more technical reference uses a sandblasted Grade 2 titanium case and bracelet, with a Grade 5 titanium bezel. Its black dial features polar blue highlights on the seconds hand, minute track, crown lacquer, and text.
The final 40 mm piece is crafted entirely from fine-brushed and polished Grade 5 titanium. It presents a soft gray tone that harmonizes with rose gold accents on the hands and markers. This model, like the others in its size, uses the TH50-00 movement. When fully charged, it can run for up to 10 months, making it a suitable companion for both extreme environments and daily wear.
