Garmin unveils new smartwatch that can run for 90 days nonstop

Garmin has unveiled the new Enduro 4 smartwatch, designed for extended training sessions, hikes, and expeditions. The model’s main advantage is its long battery life: under suitable conditions, it can run for up to 90 days on a single charge.

Enduro 4 features a 1.4-inch 280×280-pixel MIP display and solar-powered Power Sapphire glass. Without using the solar panel, the battery lasts up to 36 days, or up to 90 days with sufficient light. Extended use is also possible when GPS and other satellite systems are active. During standard activity tracking, the device can run for up to 120 hours, or up to 320 hours when using solar power. With all satellite systems active, these figures reach 80 and 144 hours, respectively. However, achieving the maximum results requires sufficiently strong sunlight—Garmin assumes an illumination level of approximately 50,000 lux.

Garmin has also improved storage and navigation in the new model. Internal storage has increased from 32 GB to 64 GB, while RAM has increased by 50% compared with the previous Enduro 3. Thanks to the updated system, navigating the built-in maps is approximately 30% faster. In addition, a Perspective View mode has been added that shows more route details.

The watch measures 51×51×15.7 mm and weighs 66 g. The bezel is made of titanium, while the main case is made of fiber-reinforced polymer. Thanks to its 10 ATM water-resistance rating, Enduro 4 is also suited for use in harsh weather and outdoor conditions. The built-in flashlight can emit both white and red light. Its sports capabilities are also extensive. The watch offers more than 100 activity profiles. New features include pace targets that account for the terrain’s gradient, Stamina Zones and Stamina Curve metrics, as well as Garmin Epic, which combines different activities performed over several days or weeks into a single history.

Enduro 4 also measures heart rate, blood oxygen levels, and skin temperature. An ECG feature is also available in supported regions. In addition, users can download maps and music to the watch and make contactless payments via Garmin Pay. The Power Manager tool helps users manage power consumption by showing which active features drain the battery more quickly.

Garmin has launched Enduro 4 in the US market for $900. The model is intended especially for long hikes, mountain expeditions, and multiday outdoor adventures where access to electricity is limited.
