Basis Peak

Peak, LCD Touch, Gorilla Glass 3, Water resistant 5 Atm, Bluetooth Smart, Accelerometer, Lithium, 51 g, White Advanced tracking technology, simplified.

Peak tracks your heart rate with an advanced, wrist-based optical blood flow engine.

This engine shines light into your bloodstream just below the skin’s surface and then measures the reflection with a sophisticated optical sensor.

As your heart beats, your blood ebbs and flows, changing the amount of reflected light.

Unique algorithms translate the data gathered from the reflected light into a continuous measure of your heart rate.

The result? A deeper understanding of your fitness, activity and sleep—no chest strap needed.

A better picture of your performance.
