Heavy sweater

I guess I sweat more than average (actually I don't know what is average about this topic, but whatever).
Because of that, when I wear my wrist watch that is made of leather, I get a lot of itch on my arms.
I'm not sure whether it is due especially to the combination of leather and sweat or not.
Did anyone experience like this?

[Good work.  I've heard of that before, but I don't have that problem myself.]
