Zen-Japan Electronics Ratoc Systems Bluetooth Smart Digital Watch: Smartphone notifications
Here's the lowdown on what it can do: Track environmental conditions with slick graphical data (because who likes squinting at numbers all day?). It's got a built-in data logger that's basically a hoarder for historical data—never lose track of past conditions again. And with its spot-on thermometer and hygrometer, you'll get measurements so precise, even a scientist would nod in approval.
In short, if you're after a gadget that keeps you connected while also keeping an eye on your surroundings, this watch is your go-to. (And yes, it tells time too—just in case you forgot.)
