Currently, we have 3 versions of the band in the market: IP33, IP67 and IP68.

Look at the underside of the sensor on your bracelet. You will find either a lot number (e.g., 202308A1) or a UDI QR code.

How to read the lot number

  • The first 4 digits indicate the year (e.g., 2023 = year 2023).

  • The next 2 digits indicate the month (e.g., 08 = August).

  • For example, 202308A1 means your bracelet was manufactured in August 2023.
