What's wrong with molded polymer bracelets? I assume you're referring to the wristband?
I've really only worn one watch and it has a molded polymer wristband, and it doesn't bother me, but maybe I'm missing out on something nicer.
They don't breathe and collect sweat as if moved by a creepy fetish. They also have no style, of course, so you can look like a grade schooler while you itch your way to lasting skin problems.
For dress wear I have a selection of steel link and leather bands to match any outfit, including one steel bracelet I torch-colored myself. For casual wear and exercise I like colorful, inexpensive canvas and seatbelt-weave nylon, which are soft and breathe very well, and wash clean easily after even the sweatiest exertion.
Given the humidity this year, I've mostly stayed in the nylon. With a few carefully chosen solids and stripes, it's easy to accent any outfit, and unlike a dime-a-dozen Apple watch I actually don't mind a pop of bright color that draws some attention to what I wear.
