Venu X1

Garmin Venu X1 is a watch from 2025, sitting in the flagship band at an indicative $699.

It reads 19 of the 33 signals this comparison tracks. Full coverage of activity. Nothing at all from body composition. Rarer readings it does take: Body Battery.

By sensor class: 11 at high accuracy and 3 at consumer grade. That grade is my classification of the hardware, not a lab test. Those readings come from an optical heart rate sensor, an optical blood oxygen sensor, a GPS receiver, a barometer and an accelerometer. Blood oxygen is a spot reading you take yourself, not a continuous one.

Its 8 days per charge are the 65th longest of the 76 devices of its kind here that publish a figure. The AMOLED screen can stay always on. Built-in GPS. Rated 5ATM / 50m, fine for swimming. It weighs 34 g. On top of the tracking it also handles music on the device, contactless payments and offline maps. Case size 46mm, 7.9mm thin. No subscription is required.

June 2025, a new thin rectangular line rather than a Venu 3 replacement. Garmin thinnest watch at 7.9 mm, with offline maps but no ECG. Launched at 799 USD and repriced to 699 since.
