But wait, there's more! Snap pics from afar or dive into motion-sensing games when you're in the mood for some fun. Fancy a bit of gesture control? This ring's got you covered. Plus, with a variety of sport modes, it's ready to hustle as hard as you do. Sleek? Check. Comfy? Absolutely—with a 19.9mm diameter and 62.5mm perimeter, it's designed for all-day wear without a second thought.
