Always On Display keeps the watch face visible but shortens battery life; when off, the screen wakes on wrist raise.

The Always-On display keeps the time and complications visible with the wrist down.

Sapphire crystal resists scratches better than ordinary glass. The 8.6 mm thickness excludes the sensor bump on the back.

32 GB of storage is enough to keep music and apps on the watch for phone-free runs.

The watch charges only wirelessly; it must align with Samsung’s charging puck, and some wireless chargers may not sit flat because of the band.

The 18-hour figure comes from Apple’s August 2020 testing with pre-production watches paired to an iPhone; it varies with use.

The electrical heart signal enables ECG and bioelectrical impedance enables body composition readings. ECG and blood pressure need a Samsung phone and country approval.

Antioxidant Index is measured by holding a fingertip on the sensor for about five seconds; Vascular Load needs the watch to be worn to sleep on at least 3 of the last 14 days. These are wellness indicators, not medical diagnoses.

The L5 band helps reduce route drift caused by reflections among tall buildings and trees.

On the Bluetooth model calls and notifications work while connected to the phone; NFC contactless payments depend on country and bank.

5ATM means water resistance suitable for swimming, not diving or high-speed water sports. MIL-STD-810H refers to selected environmental tests from the military standard and is no guarantee against impacts.

Gemini can act in Samsung Health, Calendar and Clock via voice; availability varies by device, language and country.

It cannot be used with an iPhone.

Stainless steel and titanium cases were only sold in the GPS + Cellular version. The 44 mm model uses the same chip but has a different display and weight.

Ultra Wideband availability varies by region.

Apple states Blood Oxygen measurements are not for medical use and are only designed for general fitness and wellness. The ECG app is not intended for people under 22.

On the GPS model, Emergency SOS needs the iPhone nearby; otherwise the watch must be on a known Wi‑Fi network with Wi‑Fi Calling on. International emergency calling is only on the cellular model.

LTE and UMTS are only on GPS + Cellular models.
