The Huawei Watch Ultimate offers a range of safety features specifically designed for divers, making it an excellent tool for both recreational and technical diving. Here are some of the key safety features it provides:
1. Water Resistance and Depth Capability: The watch is rated for 10 ATM water resistance, meaning it can withstand depths of up to 100 meters. This is significantly deeper than many other smartwatches, such as the Apple Watch Ultra, which is limited to 40 meters[1][2][9]. The Huawei Watch Ultimate is certified under both ISO 22810 and EN 13319 standards, ensuring it meets rigorous diving equipment requirements[1][2][9].
2. Dive Modes: The watch offers four different dive modes: recreational scuba dive, technical scuba dive, free-dive, and gauge. Each mode provides specific data and safety features tailored to the type of dive being performed[2][5]. For example, it records safety stop times, oxygen partial pressure, and gradient factor, which are crucial for safe decompression[5][8].
3. Safety Reminders and Alerts: The watch includes over 20 safety reminders and real-time alerts to keep divers informed and safe during dives. These alerts can include warnings for overtime, over-depth, and other critical safety parameters[1]. It also features a built-in buzzer and motor to provide tactile and auditory feedback underwater[1].
4. Decompression and Ascent Features: The Huawei Watch Ultimate includes features like decompression stop and ascent speed alerts, surface intervals, no-decompression limit (NDL) calculator, and no-fly timer. These features help divers manage their dives safely and avoid potential health risks associated with rapid ascents or incorrect decompression procedures[8].
5. Navigation and Positioning: The watch supports advanced dual-positioning GNSS satellite navigation, which is particularly useful in Expedition Mode for overground treks. This feature helps divers and adventurers navigate back to their starting point or find their way in unfamiliar territories[3][6].
6. Health Monitoring: Beyond diving, the watch continuously monitors health indicators such as heart rate and blood oxygen levels (SpO2). It sends alerts if it detects abnormal readings, such as low oxygen levels or high heart rates, which can be critical during or after dives[6].
Overall, the Huawei Watch Ultimate is designed to enhance the safety and experience of divers by providing comprehensive data, real-time alerts, and robust navigation capabilities.
