This video presents exactly what can be done with small arduino boards. In this case, an arduino based, fully functional, programmable watch. Below is just about everything you need if you are interested in building something like this

This was a very difficult build and requires a lot of work. Before starting lay out all the pieces and think of how you want everything to be put together and start sketching on the wooden piece where things will be positioned and the appropriate holes. Include holes for the battery in the RTC module, the LIPoly Battery wires, and locations where you will be stitching the watch together along the sides. Drill the holes very carefully making sure not to break the wood. The next part in construction was the soldering and cutting of wires. Cut the wires to the appropriate lengths and start soldering according to the schematics (I would start by getting the battery all put togerther and soldered in). Be sure to remember to make a hole for the battery wires and solder everything together while the wires are in the correct position through the wooden circle. I also placed the small switch to the wooden circle as one of the first steps. Place the switch in the appropriate position and then super-glue it onto the wood. You may want to use a small clamp to hold it together while it dries. I would avoid soldering the Neopixel Ring on until the very end. Glue and solder everything in place and then add the Neopixel Ring into the construction. After all the soldering is done, start stitching things together. I would start with the battery first. BE VERY CAREFUL not to poke a hole in the battery while stitching it into the wrist band. I take no responsability for any sort of damage. Next turn on the watch to make sure that the neopixel is positioned correctly. Now just start stitching everything together.

Arduino GEMMA – Miniature wearable electronic platform: What do you get when you combine an Adafruit classic with geniuses at Arduino? The Arduino GEMMA! It’s a tiny wearable platform board with a lot of might in a 1″ diameter package. Powered by a Attiny85 and programmable with an Arduino IDE over USB, you’ll be able to realize any wearable project.

NeoPixel Ring – 12 x WS2812 5050 RGB LED with Integrated Drivers: Round and round and round they go! 12 ultra bright smart LED NeoPixels are arranged in a circle with 1.5″ (37mm) outer diameter. The rings are ‘chainable’ – connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you’re ready to rock. Read more.
