What powers TAG Heuer Aquaracer Solargraphs?
TAG Heuer launches light-powered Aquaracer Solargraphs
TAG Heuer has introduced two new Aquaracer Solargraph watch models powered by light rather than a traditional battery. The lineup includes a 40mm “Aquaracer Professional 200 Solargraph” and a 40mm “Aquaracer Professional 100 Solargraph,” both built for water and designed for durability.
According to the product summary, the 200 models come in rugged steel or titanium, and they’re rated for 200 meters of water resistance. The key differentiator is the solar energy system that converts light into power, positioning the watches as an environmentally friendlier option while still aiming for everyday toughness.
The move also fits TAG Heuer’s broader “Aquaracer” positioning: a dive-inspired brand known for legibility and sport-ready build quality. The Solargraph naming signals that the dial and watch are engineered to take in and store energy from light sources during normal wear—meaning the wearer can top up power by being exposed to light.
What this means for buyers
- Battery concerns may lessen: Light-powered watches are built to keep running as long as they receive regular light exposure.
- Still dive-ready: At least the Aquaracer 200 Solargraph is rated to 200m.
- Material choice matters: TAG lists steel or titanium for the 200 series.
If you’re comparing to standard quartz or mechanical dive watches, the Solargraph approach is the big tradeoff: you gain a self-renewing power concept, and in exchange you rely on consistent light exposure rather than periodic battery replacement.
