(Calculator) Watch Keychain

Recently, my school created a new policy in which we were no longer allowed to carry backpacks. Well that sucked because I use my calculator to find out my scores and I also use it in math.
I decided to make a keychain with a calculator on it.
I had a calculator watch lying around so i used that but this can work for most all watches.

Step 1: Materials

One watch that you want to be a keychain.
One keychain.
JB Kwik weld (optional)

Step 2: Tools

You will need:
A pair of needle nose pliers
A razor knife

Step 3: Cutting the Bands

Cut the wrist band, from the watch.

Step 4: Removing the Chain

Take the keyring and chain off.

Step 5: Creating the Keychain

Thread the chain onto the rod where the band used to be.
This part is kinda hard to explain, but hopefully the pictures can explain better than me.

Step 6: JB Weld

If you want you can make the connection more secure.
Squeeze a bit of each part out and mix.

Step 7: Applying

Apply the Kwik weld to the keychain. Allow to dry.

Step 8: Finished Project

Now your done, put it on your keyring and everything is ready to go.
