This project was initially only supposed to be an Adafruit Flora with a band of neopixels strapped on the back. There are a few problems with this approach though. Firstly, the flora can't keep track of time when it's off. The NeoGeo watch solves this by locking to gps satellites to get the current time. Without any external source, the board would have to be reprogrammed on the fly, or have a method of setting the time via button input. Secondly, the clock on the atmel328 chip is not all that accurate. This can be solved by adding extra hardware, but I didn't have the space for that.

Instead, I decided to connect the flora to my phone. This allowed the watch to always display the precise time nearly immediately when turned on and maintain the correct time, no matter how long it stayed on. It also unlocked a huge range of potential uses for the watch to interact with data from my phone.
