vivo's Watch 3 is here and it pioneers vivo's custom-built BlueOS alongside it.

The vivo Watch 3 is a single-size smartwatch that's available in two designs and colors and with two band styles (and materials). The watch body itself is 46.1mm wide and weighs 36g. It features a 1.43-inch 466x466px AMOLED display with always-on functionality.

The watch case itself is round and the glass on top is curved and borderless. The leather strap version of the vivo Watch 3 has twin lugs, while the other is lug-less and comes with silicone straps.

The watch features a stainless steel rotating crown to help navigate the UI, which doubles as a button, and there's a second button underneath.

The watch 3 runs vivo's own BlueOS. It has app support and a built-in app store. BlueOS features vivo's Jovi assistant integration, as well as an ample catalog of health and fitness monitoring features.

BlueOS has 10 built-in watch faces.

The watch uses the Star Ring health sensor to provide 8-channel heart rate tracking and 16-channel blood oxygen tracking. There's also sleep tracking and a Running coach.

There's a 505mAh battery that can go up to 16 days without Bluetooth, up to 8 days in Bluetooth mode with notifications, and up to 3 days with everything on and heavy usage.
