Garmin has a new answer for people who run or hike for days rather than hours. The Enduro 4, announced on 6 October 2026, is the company's longest-lasting GPS smartwatch with solar charging, and it went on sale in the United States the same day at a suggested price of 899.99 dollars.
On Garmin's UK store the watch is listed at 799.99 pounds (price as of 7 October 2026, 5:40 am IST). India is a different story for now. When we checked Garmin's India store on the same morning, it still listed the older Enduro 3 at Rs 74,990 and showed no Enduro 4 page, so there is no official Indian price yet.
The battery numbers, and the fine print
Garmin quotes up to 320 hours of battery life in activity mode and up to 90 days in smartwatch mode. Both figures lean on the solar lens. The 320-hour claim assumes continuous use in 50,000 lux of light with the extended battery activity mode selected, and the 90-day figure assumes all-day wear with three hours a day outdoors in the same strong light.
In practice that means a trail runner in bright conditions will get far closer to the headline than someone wearing the watch in a Gurugram office. To make the trade-off easier, the watch has preset power modes. Max Accuracy runs every tracking feature for shorter efforts, while Max Battery stretches recording for very long outings.
The screen is a 1.4-inch MIP (memory-in-pixel) display, which Garmin describes as energy-efficient, sitting under the solar lens that tops up the battery in daylight.
What is new for hills and multi-day trips
Most of the new software targets people who train on uneven ground. Grade-adjusted pace targets keep a workout in the right effort range on climbs and descents, and grade-adjusted rolling pace shows how fast you are really moving once the gradient is taken into account. New stamina zones and a stamina curve show how endurance holds up during a session and changes over weeks of training.
Garmin Epic is the feature aimed at long trips. It lets users group several activities over days, weeks or months into one record in the Garmin Connect app, add photos and see health and performance data for the whole stretch. Think of a Char Dham trek or a week on the Annapurna circuit logged as a single journey instead of a dozen separate hikes.
Maps get faster too. Garmin says the watch has 50 per cent more RAM than the Enduro 3 and a new map engine with 30 per cent faster panning, plus a perspective view that shows more detail both near and far. There is also more on board: 64 GB of memory for maps, music and data.
Indoor rowers get VO2 max and power curve figures, and rucking now lets users change pack weight during an activity and set targets such as calories burned. All of this sits alongside more than 100 activity profiles.
Build and weight
For a watch with a 51 mm case, the Enduro 4 is light at 66 grams. It uses a Power Sapphire scratch-resistant lens, a titanium bezel and a fibre-reinforced polymer case. A built-in LED flashlight has both white and red light, water resistance is rated at 10 ATM, and a new ComfortFit fabric band uses Garmin's QuickFit system for quick swaps.
How it compares on price
At 899.99 dollars, the Enduro 4 is an expensive watch by any measure. Keep in mind that UK prices include VAT while US list prices exclude sales tax, so the 799.99 pound and 899.99 dollar figures are not a like-for-like comparison.
Indian buyers who want a Garmin today have far cheaper options, such as the Garmin Cirqa smart band at Rs 25,990, or rival wearables like the Ultrahuman Ring Pro at Rs 44,999. Anyone set on the Enduro 4 should wait for Garmin India's own listing and warranty terms rather than import a US unit, since warranty and service cover can differ by country.
