The Oppo Watch X in Mars Brown is a versatile smartwatch designed to balance advanced functionality with a durable build. It features a 1.43-inch AMOLED display with a resolution of 466 x 466 pixels, protected by a 2.5D sapphire crystal cover that helps prevent scratches during daily wear. The case is crafted from stainless steel, paired with a fluororubber strap and a stainless steel buckle that fits wrists from 140 to 210 mm. Weighing approximately 80 g with the strap, the device feels substantial yet comfortable for all-day use. Running on a dual-system architecture of Wear OS 4 and RTOS, the watch provides a smooth experience with 2 GB of RAM and 32 GB of storage. You can rely on its 500 mAh battery for up to 100 hours in standard smart mode, and the VOOC Flash Charge allows a full recharge in 60 minutes, or a quick 10-minute boost for 24 hours of use. For those who lead an active lifestyle, it offers over 100 sports modes with automatic recognition for activities like running, cycling, and swimming, supported by dual-band GNSS for precise location tracking. Health monitoring is integrated through a suite of sensors that track heart rate, blood oxygen levels, and stress, while the sleep tracking system analyzes deep, light, and REM stages along with breathing rates. The build is rated for 5ATM and IP68 water resistance and meets MIL-STD-810H durability standards, making it suitable for challenging environments. It integrates seamlessly with Android 8.0 and above, giving you access to Google Assistant, Wallet, Maps, and Calendar directly from your wrist.
