There has to be something directly connected to the wearing of a watchthat
attracts bees..I have three different wrist watches running just now.Two are
standard battery operated affairs with black plastic straps.The bees tend to
crawl into my sleeves under the elastic gauntlet and then down to the wrist
inside the glove and go directly to the watch.Yes they may get pinched as
sting as a result. Other times I have been hit through the mesh at the back
 of the wrist and be hit right at the watch. If I leave the watch at home
there is no problem.  I have another battery watch that is designed to attach
to my ski teaching glove with velcro so that it is outside and I can keep
tabs on my class schedule . I think that tomorrow morninfg I will adapt it to
my bee gauntlet glove above  the ventilation point and watch to see whether
to bee go to it.At least there they will have to spike throught the glove and
my jacket sleeve. No free lunch there.
