The Redmi Watch 5 Active and the Apple Watch Ultra have distinct water resistance capabilities, reflecting their different design purposes and target user groups.
Redmi Watch 5 Active
- Water Resistance Rating: The Redmi Watch 5 Active has a water resistance rating of 5ATM, which is equivalent to a depth of about 50 meters. This rating is based on the ISO 22810:2010 standard[4][7].- Usage Limitations: While it can withstand shallow water activities like swimming in pools or near the shore, it is not recommended for hot showers, saunas, or diving. Additionally, it lacks specific workout modes for recording water sports[7].
- General Use: It is suitable for everyday wear and can handle exposure to sweat or rain, but it should not be subjected to direct impacts from swift currents during water sports.
Apple Watch Ultra
- Water Resistance Rating: The Apple Watch Ultra has a more robust water resistance rating of 100 meters under the ISO standard 22810:2010. It is also EN13319-compliant, which pertains to diving equipment[2][5].- Usage Capabilities: This watch is designed for more demanding water activities, including recreational scuba diving up to 40 meters with compatible third-party apps. It is also suitable for high-speed water sports[2][5].
- General Use: Like the Redmi Watch, it can handle exposure to sweat and rain but is not permanently waterproof. Its water resistance may diminish over time.
In summary, the Apple Watch Ultra offers significantly better water resistance and is more versatile for various water activities, including diving, compared to the Redmi Watch 5 Active. The Redmi Watch 5 Active is better suited for casual water exposure and everyday use.
