Rugged by Design

The T-Rex 3 Pro is built different, just like you. Take on any adventure with military-grade toughness, dual diving certification, a scratch-resistant sapphire glass screen, and a vibrant 3000-nit AMOLED display that stays clear even under direct sunlight. This ultra-high brightness ensures exceptional visibility in any outdoor condition, so your data is always easy to read. All of it is framed by a corrosion-resistant, high strength grade 5 titanium bezel.

Endure Any Environment

Along with hardware that’s resistant to temperatures as low -40°C, the T-Rex 3 Pro features a smart Low Temperature Mode that, when enabled, keeps vital software functions of the watch operational in environments as cold as -30°C. Enable Low Temperature Mode and Glove Mode to stay in control even in extreme cold.

Ski Mapping

Find your nearest ski resort and navigate with detailed maps that include cable cars, color-coded slopes, and clear route guidance for groomed runs as well as off-piste, backcountry, or telemark routes.

Industry-Leading GPS

Accurately track every move, even under tall buildings or dense tree cover. Dual-band support from six satellite systems delivers a fast, reliable connection, ideal for demanding outdoor adventures from rugged hikes to intense trail races.

Every Beat Counts

The T-Rex 3 Pro is equipped with our advanced BioTracker sensor, delivering highly accurate heart-rate tracking even in challenging outdoor conditions. For those who want to push precision to the limit, pair it with the Helio Strap — our industry-leading arm-worn heart-rate monitor. Together, they provide pro-grade accuracy you can rely on, from steep hikes to intense trail races, ensuring every training decision is backed by the most precise data possible.

With over 180 sport modes, including winter sports like skiing and snowshoeing, it adapts seamlessly to your training lifestyle and helps you perform at your best every step of the way. From the ocean to the mountains, the T-Rex 3 Pro is designed to keep up with you.

Pro-Grade Waterproofing

When the Trail’s Dark, Stay Bright

Train earlier, go longer, and stay visible with a built-in two-color flashlight made for low light and late hours. Choose soft red for low interference, bright white for clarity, switch to Boost Mode for powerful visibility when it’s needed. An SOS signal adds extra peace of mind wherever you roam.
