Since this was a request here is the Sportsman watch in a few wrist shots. I put it on the Ball deployant during these pictures.
The new strap has a rubber backing. It is a bit on the stiff side right now and the rubber makes it less easily slide into place and through the keepers. I've had it in water a few times and it seems to be pretty resistant to being wet. The strap width is 21mm which is not a size I have many of . It would be better on the Ball ruber either from the diver of from the older 43mm Nighttrain. I'm going to see if I can find a nice 21mm distressed brown leather strap to put it on. I think that will work well.
