Smartwatch mode runtimes vary by model and configuration, typically from about 10 to 48 days (some models extend that with solar charging). GPS-mode runtimes also vary; manufacturers report GPS use up to about 149 hours on select models, with longer durations possible when solar charging is factored in.

They track a wide range of metrics including heart rate, blood oxygen (SpO2), sleep duration and stages, stress, VO2 Max, steps, calories, respiration/respiratory rate, and advanced measures such as heart-rate variability (HRV) status. Some models also offer ECG-capable apps (availability varies by region).

Common connectivity options include Bluetooth, Wi‑Fi and ANT+. Many models have a built-in speaker and microphone for on-wrist calls when paired to a phone. Select watches offer LTE or inReach satellite connectivity for two-way messaging and SOS services (these options may require an active subscription and are model-dependent).

Typical materials and durability features include silicone bands and fiber-reinforced polymer (FRP) bodies; several models add titanium bezels and scratch-resistant sapphire lenses. Some watches also carry MIL‑STD‑810 ratings for thermal and shock resistance. Specific materials and ratings vary by model.

Select models offer off-grid features such as inReach satellite or LTE connectivity for two-way messaging and interactive SOS (these services typically require a subscription). Some marine-focused descriptions list boat-mode features for vessel control and note extended offshore satellite coverage on particular models. Availability and range vary by model.

Many models include onboard music storage and playback, and several support Garmin Pay contactless payments. Payment availability depends on supported banks, networks and region, and not every model includes both features.
