I just put one on my watch and they are much more comfortable then the original.
I have a fairly fat wrist and i have a couple of holes to spare
Both the nylon and the canvas are the same price at $15 each plus $2 delivery anywhere in NZ any quantity
I only got 5 of each to cover my costs for the ones I wanted

I will give them a week to sell on here then they will go on TM for $24 each
