The Huawei Watch Ultimate is designed to track both depth and time during a dive, making it a versatile tool for divers. It supports four diving modes: Recreational dive, Technical dive, Freedive, and Gauge. Each mode offers real-time monitoring of diving data, including depth and time, along with other relevant parameters such as surface time and diving logs.
- Recreational dive: This mode is suitable for no-decompression diving with nitrogen and oxygen mixtures. It includes safety stop guidance, which helps divers manage their ascent safely by monitoring depth and time to avoid decompression sickness.
- Technical dive: This mode is for technical decompression diving with multiple cylinders containing helium, nitrogen, and oxygen mixtures. It does not include safety stop guidance but still tracks depth and time, allowing divers to manage their dives based on complex gas mixtures and decompression requirements.
- Freedive: This mode is for breath-hold diving, where the watch tracks depth and time without the need for decompression calculations. It focuses on monitoring the diver's descent and ascent rates, ensuring safe practices.
- Gauge: This mode functions as an underwater timer, displaying only the depth and time. It does not provide decompression calculations or detailed tracking but is useful for simple dives where only basic information is needed.
The watch also supports features like apnea training and testing, which help divers improve their breath-holding abilities. Additionally, it provides a no-fly time after each dive, advising when it is safe to fly again to avoid decompression sickness.
In terms of technical specifications, the Huawei Watch Ultimate is water-resistant up to 100 meters, complying with ISO 22810:2010 and EN 13319 standards, making it suitable for deep-water activities[2][4][9]. The watch's depth sensor ensures accurate tracking of depth during dives, while the digital stopwatch and elapsed time counter handle time tracking effectively[7].
