Lily 2

Garmin Lily 2 is a watch from 2024, sitting in the budget band at an indicative $249.

It reads 14 of the 33 signals this comparison tracks. Nothing at all from body composition. Rarer readings it does take: Body Battery.

By sensor class: 10 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 and an accelerometer. Blood oxygen is measured during sleep, not continuously through the day.

Its 5 days per charge are the 70th longest of the 74 devices of its kind here that publish a figure. It has a transflective MIP screen. No GPS of its own, it borrows the phone's. Rated 5ATM, fine for swimming. It weighs 24 g. Case size 35.4mm. No subscription is required.

Small (35.4mm) fashion watch; Gen 4. Connected GPS only, no barometer/floors, no VO2max.
