Hope this Instructable is helpful. If you have any questions feel free to comment and I will try to get back to you as soon as possible.

Step 1: Step 1

Take first section of 2.5ft paracord length and make a loop around the clasp by bringing both ends of the cord under and through the clasp, then take ends through the loop that was just made (See picture with pink cord) and pull tight

Step 2: Step 2

Take the watch and feed one end of the cord up and into the gap and one end down into the gap of the watch. This will help transition into the weave. Pull tight and repeat on other side.

Step 3: Step 3

Start Paracort weave (see my other instructable if you do not know how to perform this weave). Weave until done with that side, then repeat on other side until done.

Step 4: Step 4

Once done with the weave and the clasp is flush with the end of the weave, cut end of the cord right up to the weave, this will be melted and pressed to the bracelet for clean and secure melt
