You'll need:
About 10 feet of paracord,
Scissors,
Lighter,
Tape measure,
Hemostats,
Watch,
5/8" side release buckle.
Instructions
The amount of paracord that will be used depends on your wrist size, cord, and tying technique(tight/loose). For wrist about 8.5 inches is used around 8 or 9 feet after finishing the bracelet/watchband. So using 10 feet is usually a safe estimate for most folks, since having too much cord is better than coming up short when making your project.
To Begin
Measure about 20 inches from one end of your length of paracord. This is where you'll loop onto one end of your side release buckle. Once attached, you'll have the longer section which will be your working end and the shorter end which is just attached to the buckle ends and will be tucked in when finishing the bracelet/watchband.
Add the Watch and Adjust for Wrist Size
If making as a watchband, this is where you take the strands of paracord from the looped section of the buckle and run them over the watch pin, under the watch, and over the other watch pins. Then you loop the paracord around the other buckle end twice.
At this point, you'll measure the distance between the buckle ends for your wrist size. The distance should be equal to your actual wrist measurement. The weaving process will stretch this original spacing of bracelet/watchband about another inch after tightening as you reach the finishing point.
Now bring the cord ends back thru the watch pins, along side your first pass, and around the starting buckle end.
Begin Weaving
Now you begin weaving the long working end of your paracord. The shorter end will be left out until it's time to finish the bracelet/watchband, and tuck it into the weave.
This weaving process is called 'weaving with three warps'. You'll be going around the outer cord with your working strand, under the center two cords(which you treat as one cord), and around the other outer cord.
You weave it back over the center two strands and around the outer, continuing this process, back and forth. Try not to leave too much slack as you go to keep the weave uniform. Every couple of weaves, push your work tight, up towards the starting buckle end.
Threading the Watch
Once you've reached the point where your watch will be centered, push the watch tight against the woven cord and bring your working strand thru the pin along side the other cords under the watch, and back thru the other pin.
Continue on the Other Side of the Watch
Continue weaving the paracord, keeping a uniform look, and tightening as you go.
A pair of hemostats can help work the cord around as you get close to the buckle end, making the last couple of weaves.
Finishing Up
To finish up, you'll take the working strand around one of the outer cord, so it's coming thru the under side of the bracelet/watchband.
Take your hemostats and work them thru about three of the center weaves, towards the buckle end. Grasp the working strand and pull it back thru the center weaves.
Trim the end with your scissors, quick melt the end to prevent the cord from fraying, and tuck it under the weave.
Now do the same with the shorter end of cord and you're done.
If you measure again, you'll see that the finished length is about 1 inch longer than the starting measurement. This will vary depending on your tightening of the weave as you go, but should make for a loose/comfortable fit.
