Some time ago an episode of Craig Boddington 'Tracks Acrss Africa' showed him wearing a watch cover similar to this one. We were asked repeatedly by customers where they could get one and up until now we did not have a good answer. The design is based on those used by the Israeli military. Unlike other models that attached to the band, these simply slip over the watch that is already on your wrist. It is made of neoprene which provides more protection than nylon or webbing. The tight fit the neoprene provides eliminates any game spooking reflection from your watch and also protects it while hunting, hiking, doing yard work or any other outdoor pursuit. I wear one while shooting my double rifle to prevent my watch clasp from opening during recoil. One of these is not enough...your purchase price is for two covers.
