At the same time, NO.1 F1 Smartband and NO.1 F2 Smart watch band also uses IP68 waterproof level. So, What does IP68 mean? What is the difference of IP67 and IP68 Waterproof?

    “IP68 is one of the most advanced dustproof and waterproof specifications”

    Nope, IP68 is a time limited controlled conditions static immersion certification only. ATM ratings on the other hand are 24hr immersion for all water related activities up to the rated depth. In fact, you would be hard pressed to find any sports watch with less than a 3ATM rating. Furthermore, anything less than a 1ATM (10 meters) rating isn’t even a water activities rated watch.

    “They have the highest waterproof rating in the world.”

    Garmin smart watches are rated to as much as 5ATM (50meters /150ft). And Garmin is not the only ones with ATM ratings.

    1. Thanks for your detailed explanation. You are right, as the development of wearable industry, we still have a long way to go.

      1. Hi, I have an F2 watch, what are the usage parameters for it? Can be used in rain, during swimming (1m dept) can I press buttons under water? How about the temperature? Can be used in sauna? Thanks

        1. For more details, you can visit NO.1 F2 official website. And yes, F2 is IP67 waterproof, you can use it in rain, you can also press buttons underwater.
          About the temperature, F2 accesses the data of Fundo bracelet, and read the temperature results. So it depends on your phone.

  2. Thanks, so can I use it during swimming workout? What is the official usage and storage temperature rnage for F2?


    1. Yes, F2 is made as the smartband with a watch modeling. So the official usage is the same as a smartband. Temperature range? As I said, F2 doesn’t have a built-in thermometer, I don’t know the phone’s temperature range.
