Oraimo BT Calling Smart Watch (OSW-831N)- Rose Gold
- A vivid 1.32-inch AMOLED display with 466×466 resolution and anti-scratch panda glass gives the OSW-831N a sharper, more vibrant screen than entry-level smart watches, with a 2.5D curved finish that looks and feels premium on the wrist.
- Built-in Bluetooth 5.3 calling lets you answer and make phone calls directly from your wrist, keeping you connected during workouts or when your phone is out of reach.
- A larger 260mAh battery delivers up to 11 days of typical use and 31 days on standby, with a full recharge taking just 2.5 hours, so it needs far less frequent charging than most rivals.
- Comprehensive health tracking includes 24/7 heart rate monitoring and blood oxygen (SpO2) tracking, plus 140+ sports modes to log workouts ranging from running to swimming.
- An IP68 water and dust resistance rating, combined with an ABS/PC/stainless steel build weighing 74.52g, makes the OSW-831N durable enough for daily wear, exercise, and light rain exposure.
