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 168 hours of battery life with the always-on display running

10 ATM of water resistance

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

The electrical sensor is not on the list, yet Garmin states the ECG app separately

A screen covered in Corning Gorilla Glass or sapphire crystal

Things to consider

Garmin names this watch's processor nowhere

Battery capacity is not published in mAh; hours of use is all there is
