ALL DAY, EVERY DAY

Conquer every hour with advanced training features, 24/7 health and wellness monitoring, and up to more than a month of battery life with the Power Sapphire™ solar charging lens¹ and a rugged watch case designed for smaller wrists.

LONG BATTERY LIFE WITH SOLAR CHARGING

Get up to 14 days in smartwatch mode with solar charging in 3 hours of direct sunlight (50,000 lux) per day and up to 46 hours in GPS mode with solar charging (assumes continuous use for entire period in 50,000 lux conditions).

BUILT-IN LED FLASHLIGHT

Variable light intensities and a red safety light give you greater awareness while you train in the dark, providing convenient illumination when you need it. The strobe mode can even match your running cadence.

HILL SCORE

This feature measures your capability for running uphill and evaluates your progress over time based on your VO2 max and training history. It measures your running strength on steep ascents and running endurance on long ascents and provides a score based on your performance over time.

ENDURANCE SCORE

This feature measures your ability to sustain prolonged efforts and combines training data from all your athletic pursuits to help you understand how training impacts your overall endurance. This dynamic measurement uses your VO2 max, short-term/long-term training loads and other factors to gauge your fitness progress beyond just VO2 max.

RUGGED BY DESIGN

The resilient athletic design features a 1.2″ scratch-resistant sapphire solar charged display, responsive touchscreen, traditional buttons and 42 mm fiber-reinforced polymer case with a steel bezel and rear cover. The watch is tested to U.S. military standards for thermal, shock and water resistance.

KNOWLEDGE IS POWER

Your health and training data should be easy to interpret and provide actionable insight. Begin each day with a customisable morning report, and see a daily summary of health and wellness information. Use the training readiness feature — which looks at a variety of different health metrics to help you maximise your training efficiency and recovery² — to prevent burnout.
