"A $20 watch that tells time and mirrors notifications, but is not a serious tracker."
IP68 waterproofing means it's designed to survive submersion up to a manufacturer-specified depth (usually 1.5m), but at this price point, inconsistent manufacturing means you shouldn't trust it for swimming.
This is for someone who wants the aesthetic of a smartwatch and basic notifications for the lowest possible price. It's also a potential first 'smart' watch for a child where loss or damage is a primary concern.
Anyone even moderately serious about fitness tracking should skip this, as the sensor data will be unreliable. If you value a stable connection, a polished app, or data portability, you must spend significantly more.
