The Huawei Watch Ultimate's liquid metal casing, made from a zirconium alloy, significantly enhances its durability underwater through several key properties:
1. Strength and Hardness: The zirconium-based liquid metal case is 4.5 times stronger and 2.5 times harder than stainless steel, making it highly resistant to the intense pressures encountered at depths of up to 100 meters[1][3]. This strength is crucial for withstanding the water pressure without deforming or cracking.
2. Corrosion Resistance: The liquid metal alloy is less prone to corrosion compared to other metals, which is particularly beneficial in saltwater environments where corrosion is more likely to occur[4][9]. This resistance ensures that the watch remains functional and structurally sound even after repeated exposure to seawater.
3. Lightweight: Despite its enhanced strength and hardness, the liquid metal case is also 17.4 times lighter than stainless steel, which helps maintain the watch's comfort and wearability during prolonged underwater activities[1]. This lightweight property is advantageous for divers who need to move freely without the burden of a heavy device.
4. Aerospace-Grade Durability: The use of zirconium-based liquid metal provides aerospace-grade durability, indicating that the watch is designed to withstand extreme conditions, including those encountered in deep-sea diving[3][5]. This level of durability ensures that the watch can function reliably in challenging environments.
5. Water Resistance Certifications: The Huawei Watch Ultimate is certified to the ISO 22810:2010 standard for water resistance and complies with the EN 13319 standard for diving equipment, allowing it to support dives up to 100 meters[3][7]. These certifications validate its ability to withstand underwater pressures for extended periods.
Overall, the liquid metal casing of the Huawei Watch Ultimate combines strength, hardness, corrosion resistance, and lightweight properties to provide exceptional durability underwater, making it an ideal choice for divers and those engaging in water sports.
