English: This came from a cheap dollar store 7 segment LCD display wristwatch I won at an arcade at least 10 years ago. It had an external crystal oscillator, so that should not be located in this chip. From what I remember this watch had two buttons, could display the date as well as have timers.

This was encased in a black goop (similar to calculator chips) which I was able to heat up and remove the chip from. Lighting was done by shining a single LED down the other eyepiece of my microscope in order see more details.

Colour correction was performed in Photoshop because the LED washes out most of the colours.

This chip is around 1mm^2.
