Ultrahuman Ring Air Size 08 Bionic Gold

The Ring Air Size 08 Bionic Gold tracks activity, sleep, and health metrics through advanced sensors.

This Ultrahuman fitness tracker suits users who want continuous monitoring without the bulk of a smartwatch. Its lightweight titanium build and hypoallergenic epoxy resin inner coating make it comfortable for all-day and overnight wear, while the screen-free design keeps your focus on insights rather than notifications.

Bluetooth v5.0 connectivity syncs your data with iPhones running iOS 15 or later and Android devices running Android 6 or later. The ring is water resistant up to 100 meters for up to 12 hours, so you can wear it during swimming or showering. Battery life lasts 4 to 6 days on a full charge, reducing the need for frequent recharging.

Model 170115 in gold comes with a 1 year manufacturer's warranty.
