The official tech specs don't reveal much, but that's okay because we've got plenty of daylight to finish this teardown. Here's what we do know:

Low-power, 1.25-inch, 64-color, LED-backlit e-paper display

6-axis inertial measurement unit, compass, ambient light sensor, microphone

Bluetooth 4.0

Lithium-ion polymer battery with a battery life of up to 7 days between charges

Apart from the e-paper display, what sort of technological whizbangery makes for 7-day battery life in a modern smartwatch? We're about to find out.
