Garmin Enduro 3

Round smartwatches by Garmin can be categorized in the high price range and recommended to demanding athletes, including marathon runners, triathletes, Ironman participants, etc. The device represents the third generation in the Enduro lineup, differing from its predecessor with an updated heart rate and blood oxygen level sensor, ECG capability, a new interface (with a more intuitive widget display), and improved battery life.

Thanks to the solar battery, the Garmin Enduro 3 smartwatches can operate up to 90 days without charging under regular use (and up to 36 days without solar supplementation). Even with GPS constantly on, the battery life is from 5 days, sufficient for ultramarathons, challenging outdoor ventures, etc. The model features a 1.4-inch color screen with a transflective matrix that consumes little energy, offering excellent visibility even in direct sunlight.

Notably, there's an expanded set of metrics for tracking, including HRV, VO2Max, and air temperature. The proprietary GPS module supports topography and track navigation. Other features include 32 GB of internal memory (for music downloads, with a player included), support for contactless payment via Garmin Pay, and a built-in flashlight. High durability, wear resistance, and water protection are confirmed by compliance with 100 WR and MIL-STD-810 standards: sapphire glass protects the watch face, and a titanium bezel complements the plastic case.
