TK79 1.47 inch IP68 Waterproof Smart Watch - ECG, Blood Glucose, Blood Oxygen Monitoring
At the heart of this gadget? The Realtek 8762D main control chip—because even smartwatches need brains.
Ever wondered what keeps an eye on your heart? Meet the VC8808 ECG sensor, your personal health detective.
IP68 waterproof level means you can wear it in the shower (or while crying over your step count).
Thanks to the ST8321 weight sensor, it knows when you've been hitting the snacks a bit too hard.
Peek at your stats on the crisp 1.47-inch TFT HD screen—because squinting is so last year.
A 260mAh battery keeps it going, so you don't have to worry about it dying before your marathon... of binge-watching.
Navigate with ease using full touch + encoder—no PhD required.
Charging is a snap with magnetic suction; it practically does it for you while you nap.
From freezing -5 to toasty 45 degrees Celsius, this watch has more temperature range than your mood swings.
Speak your language? It probably does too, with support for everything from Simplified Chinese to Turkish (no, not the bird).
It's like having a mini doctor on your wrist, offering everything from pulse therapy to sleep monitoring—because who needs sleep labs?
And because we know you're more than just your vitals, it's packed with extras like multi-sports mode, breathing training, and even a find phone feature (for when you lose it in the couch... again).
