Are there any good alternatives for apple watch bands without fluoroelastomer?

I don't believe such a silicon band exists anywhere. Is there some reason you are not considering a metal, leather, or woven nylon watch band?

Here’s what ChatGPT has to say about Apple watch bands.

Apple Watch bands are made from a variety of materials, such as fluoroelastomer (used in the Sport Band), woven nylon, stainless steel, and leather. The presence of per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals," is more commonly associated with products requiring stain resistance, water repellency, or durability enhancements.

Fluoroelastomer, used in some Apple Watch bands, is a synthetic rubber material that may belong to the broader category of fluorinated compounds, but it is not necessarily the same as PFAS. PFAS typically refers to a specific subset of fluorinated chemicals used for their nonstick and water-repellent properties.

Apple does not explicitly disclose whether PFAS are present in their watch bands. If you're concerned about PFAS exposure, you might consider contacting Apple support directly for detailed product information or choosing a band made of natural or non-synthetic materials.

there are so many third party bands out there so

heck you can even get empty braces and make your own band
