Nonary Blueprints

This is the bracelet from 9 Hours, 9 Persons, 9 Doors.
I'm planning to cosplay Junpei, and I need a bracelet. The official one is over 150$ on ebay and I'm not rich in the moment, so I'll have to make my own~

I found a picture of the watch's instructions on ebay, which had this diagram on it, but since it was a picture taken from an angle I had to fix the perspective using photoshop. I then decided to retrace everything on Illustrator, and here is the result~

I'll start working on the bracelet itself once I decide which materials I'm gonna use. I'm thinking of putting LEDs in there, but I'm not sure I'll be able to fit everything in such a small piece, so we'll see how it goes.
