Galaxy Watch Ultra (2025)

CONSIDER

Great choice if these matter:

Health Tracking
Android phone owners
Daily Use

Watch out for:

Samsung does not name this watch's processor; only the core count and clocks are given
By Samsung's own footnotes, ECG and irregular rhythm notifications are not enabled in every country

Regret riskLOWlimited data

Main risks

Samsung does not name this watch's processor; only the core count and clocks are given
By Samsung's own footnotes, ECG and irregular rhythm notifications are not enabled in every country
The 60 hours the maker states were measured with the always-on display running; other use changes the figure
Wireless networking stops at Wi-Fi 4

The risk level is computed from the release date and verified weaknesses. The confidence score appears only once enough owner reports exist.

Alternatives

Apple Watch Series 11 42mm

Apple Watch SE 3 44mm

This box relies only on verified specs, the release date and editorial assessment; owner reports join them as they come in. We do not predict prices.

Health

What does it measure on the health side?

The maker's own official specifications. A sensor being present does not mean the feature is enabled in every country.

Editorial Analysis

Strengths and points to consider

The Kacbu editors' assessment of the specifications the maker publishes. We do not test devices ourselves, so nothing here is a measured result. Anything taken from an independent review is shown with its publication and date in the Press section.

Strengths based on the specs

Up to 3000 nits on an always-on Super AMOLED panel

Dual-band GNSS — not the same thing as simply having a GPS receiver

Alongside the electrical heart sensor, the ECG app and irregular rhythm notifications are stated too

10 ATM of water pressure and an IP68 dust rating, documented separately

590 mAh, the largest battery here, in a 60.5 gram titanium case

Things to consider

Samsung does not name this watch's processor; only the core count and clocks are given

By Samsung's own footnotes, ECG and irregular rhythm notifications are not enabled in every country

The 60 hours the maker states were measured with the always-on display running; other use changes the figure

Wireless networking stops at Wi-Fi 4
