Samsung Galaxy Watch7 44 mm Bluetooth / Apple Watch Series 6 (40 mm, GPS)

The 2000-nit peak helps readability in sunlight; using the always-on display shortens battery life.

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

A fast wireless charging puck is in the box, but no wall adapter.

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

The L5 band helps separate signals reflected by tall buildings and trees; dual-frequency mode can increase battery use.

Availability of ECG and blood pressure depends on country and paired phone; blood pressure measurement is not offered in the US.

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.

Energy Score turns sleep, activity and heart data into a daily readiness score; AGEs Index is experimental and not for diagnosis.

This version has no cellular connection; calls and notifications come through the paired phone.

5ATM describes water resistance suitable for surface swimming; it is not for diving or high-speed water sports.

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.

Suitable for shallow-water swimming in a pool or the sea, but not scuba diving, waterskiing or high-velocity water.

Ultra Wideband availability varies by region.

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.
