Best Electronics Z78 Smart Watch: Heart rate monitor
Meet the Smart Watch Z78—your new wrist-bound buddy that doesn’t just tell time but keeps up with your hustle. Rain or shine, swim or sprint, its tough, waterproof build has your back (or rather, your wrist). Fancy a peek at how your heart’s doing? The built-in heart rate monitor and sleep tracker are like having a mini doctor on call, minus the white coat. And hey, with Bluetooth calling, you can chat away without fishing your phone out of your pocket (because who has time for that?). Plus, that golden finish? It’s not just sleek; it’s basically jewelry that tracks your steps.
