Xiaomi Redmi Watch 4, Obsidian Black

Redmi Watch 4 packs an ultra-large 1.97" square AMOLED display (60Hz, up to 600 nits) into an aluminium alloy frame with a rotating crown, so it looks and feels far above its price.

Built-in multi-system GNSS tracks your runs without your phone, while heart rate, blood oxygen and sleep monitoring run around the clock. Take calls from your wrist over Bluetooth, swim with 5ATM water resistance, and go up to 20 days on a charge.
