Carrefour T-Rex 3 Smartwatch with GPS and Military Durability: GPS and dual-band GNSS tracking
If a G-Shock and a high-end fitness tracker had a love child, it might look something like the T-Rex 3. This rugged smartwatch is built for the kind of people who think 'extreme conditions' is just another Tuesday. It packs built-in GPS and dual-band GNSS tech, which means your location data isn't just accurate—it's pinpoint precise, whether you're lost on a mountain trail or just trying to shave seconds off your morning run. With 5 ATM water resistance, it laughs in the face of rain, swims, and even depths up to 50 meters, making it as at home in the ocean as on dry land. Throw in a digital compass and military-grade durability for shock and impact, and you've got a device that's basically indestructible. It tracks everything from hiking to cycling with multiple sports modes, serving up fitness insights without breaking a sweat. For adventurers or anyone who needs a watch that can handle more than just telling time, the T-Rex 3 is the rugged, smart companion that won't let you down.
