What did Samsung fit inside the Gear Fit?

1.84” Curved Super AMOLED touchscreen display (432 x 128 pixels)

180 MHz ARM Cortex M4 CPU

Accelerometer, gyroscope, and heart rate sensor

Battery good for 3-4 days of normal use

Bluetooth 4.0 LE

It's a tidy little package, but you know how this works: it's all gotta come out.
