Why WIS Created Our Own Rubber Strap Blend

The Story Behind Our Non-Toxic, Ultra-Comfortable Watch Straps

At Watch Innovation Straps (WIS), we didn’t just want to sell rubber watch straps—we wanted to redefine them. After years of being dissatisfied with industry-standard FKM rubber, which many strap companies still use despite its toxic composition and poor performance, we made the decision to develop something better.

The Problem with FKM: Stiff, Toxic, and Overused

FKM rubber has long been a go-to material in the watch world, but as watch lovers, we noticed its downsides quickly. It’s stiff, quick to pick up dirt, and worst of all, it often contains PFAS chemicals—substances known to be harmful to human health. For something worn directly on the skin every day, we knew we had to find a safer, more comfortable solution.

A 2-Year Journey to the Perfect Rubber Blend

After testing products from four different manufacturers, we finally landed on our proprietary silicone-rubber blend. It’s hypoallergenic, non-toxic, and PFAS-free—backed by FDA test results for safety. Our blend combines the durability of rubber with the soft, supple feel of premium silicone, resulting in what we—and many of our customers—believe is the most comfortable rubber strap on the market today.

Built for Everyday Comfort and Horological Style

Whether you're wearing your watch to the office, the gym, or on a dive trip, our rubber straps offer unmatched comfort without compromising on style or performance. They’re sweat-resistant, waterproof, and built with quick-release spring bars for easy strap changes—so you can switch up your look in seconds.

Safe for Your Skin. Strong for Your Watch.

When you choose a WIS rubber strap, you’re choosing a strap that’s safe for daily wear, gentle on your skin, and engineered to last. You don’t have to worry about hormone-disrupting chemicals or premature wear and tear—just enjoy your timepiece with confidence.
