OPPO Watch owes its slim profile to this AMOLED screen, combined with a 4.5mm aluminum frame and 3D curved glass crystal. The back of the watch uses an integrated 3D ceramic design and sensors designed to maximize contact with the skin without exerting pressure. Each watch comes with a band made of either Italian calfskin or fluoro rubber and available in a variety of colors to suit different occasions, from meetings to workouts. The band can be easily removed by pushing a single button. OPPO Watch can also be used for listening to music and making payments. An internal app store offers a variety of third-party apps for social networking, travel, entertainment, and more. In addition, the watch’s style-matching AI watch face can generate a wallpaper that matches a photo of the user’s outfit, inventing a stylish new look every day. Health and fitness has become a hot topic, especially among office workers, who feel an increasing need to develop good exercise habits and monitor their health. OPPO Watch provides a health monitoring system and various fitness tracking functions through which OPPO hopes to make exercise easier for its users. The watch contains 5 exercise sensors, can monitor a range of exercise scenarios, and is water resistant to 50 meters, making it easier to incorporate exercise into any lifestyle. Beyond exercise features, OPPO Watch can monitor sleep quality, generating a sleep report of the user’s duration of deep sleep, light sleep, and awake time. Additionally, the watch can constantly monitor heart rate, and generate a chart showing heart rate over the past 24 hours. Other functions such as activity and breathing reminders and monthly cycle monitoring for female users are also available. This is a watch that truly helps users take care of their health across the board. OPPO smartphone users can quick-pair their phone’s health app with OPPO Watch to access additional health & fitness services. Users of other Android smartphones can access the same services by downloading the HeyTap Health app. Dual-Chip Endurance & Watch VOOC Flash Charging For users who often find themselves feeling low-battery anxiety, OPPO Watch has its own Dual-Chip Endurance System that switches between a Snapdragon chip and an Apollo chip depending on power usage mode. In Smart Mode, the watch reportedly has a 40-hour use time on one charge. In Power Saver Mode, only basic functions such as notifications are enabled, and use time reportedly reaches 21 days on one charge. Drawing on its expertise in the field of flash charging, OPPO has also developed its own all-new Watch VOOC Flash Charging technology, which uses the same battery system as OPPO smartphones. This technology ensures both charging speed and safety. A full charge takes 75 minutes, and 15 minutes of charging time reportedly yields a 46% charge, which corresponds to approximately 18 hours of use time – enough for an entire day of use. Watch VOOC Flash Charging, combined with the Dual-Chip Endurance System, clearly demonstrates a higher-tech, higher-quality approach to the smart watch experience.
