When it comes to dive watches, one accessory has stood the test of time: the rubber strap. Even with the rise of NATO straps, stainless steel bracelets, and high-tech materials, divers around the world continue to rely on rubber. But why does this material remain the undisputed choice for underwater adventures?

Let’s dive into the reasons behind the enduring trust in rubber straps.

1. Built for Water

Unlike leather or canvas, rubber is naturally waterproof. It doesn’t absorb moisture, swell, or warp, making it perfect for long dives or extended time in wet environments. Saltwater, chlorine, or rain—rubber straps handle them all with ease.

Pro Pick: ZULUDIVER 286 NDL Italian Rubber Dive Strap – crafted from Italian HNBR rubber, designed for both deep dives and daily wear.

2. Resistance to Harsh Elements

Divers face more than just water. Straps are exposed to UV rays, sweat, oils, and extreme temperatures. High-quality rubber—especially HNBR (Hydrogenated Nitrile Butadiene Rubber)—is resistant to cracking, fading, and chemical damage. This durability gives divers confidence that their straps won’t fail mid-dive.

3. Comfort and Flexibility

A dive watch is often worn for hours at a time, both above and below the surface. Rubber straps are soft, flexible, and contour naturally to the wrist. They don’t pinch or dig into the skin, even when worn tightly over a wetsuit.

Fun Fact: Many modern rubber straps are lightly scented (like vanilla) to avoid the unpleasant smell of traditional rubber.

4. Secure Fit for Safety

When diving, a secure fit can mean the difference between keeping or losing a valuable timepiece. Rubber straps typically feature robust buckles, reinforced holes, and wide keepers that keep the watch firmly in place—even under pressure. Some also offer extended lengths to fit comfortably over wetsuits.

Rugged Option: ZULUDIVER 285 Italian Rubber Diver’s Strap – engineered for maximum strength with stainless steel hardware.

5. Tradition Meets Innovation

Rubber dive straps carry decades of tradition, dating back to the 1960s with the introduction of Tropic straps. They were iconic among divers for their perforated design and durability. Today’s straps combine that heritage with modern technology, offering superior comfort, style, and resilience.

Final Thoughts

Rubber straps remain the trusted companion for divers because they’re waterproof, durable, comfortable, and secure. From vintage-inspired Tropic styles to advanced HNBR designs, they continue to bridge tradition and modern innovation.
