Shop The Collection
Refined Aesthetics, Engineered for Comfort
The highly detailed crocodile texture and meticulous contrast stitching around the edges offer an elegant look that traditional rubber straps simply can't achieve. But the true innovation lies in its exceptional wearability.
Crafted from premium FKM rubber, the strap boasts a remarkably smooth underside for an exceptional wrist feel. We incorporated a specially designed underlying indent that actively promotes airflow, keeping your wrist comfortably dry. Mirroring the profile of our traditional leather bands, the strap is robust and prominent at the lug connection point, then elegantly tapers down to the buckle to keep bulk to an absolute minimum when fastened.

Pro Tip: The FKM Advantage
Because FKM rubber is naturally anti-static, your strap won't attract lint or dust, keeping your watch looking pristine throughout the day. It also dries almost instantly and resists damage from salt water and UV rays, ensuring the strap remains supple and vibrant even after years of exposure to the elements.
A Perfect Companion For:
-
Dress Timepieces: Instantly elevates your watch with a premium, exotic aesthetic that real leather provides, but without the fragility.
-
Sport & Dive Watches: Fully waterproof, sweat-resistant, and highly resilient—ready for the deep end, the gym, or the trail.
-
Everyday Wear: The breathable underside and ergonomic taper provide lightweight, all-day comfort that seamlessly transitions with any outfit.

Frequently Asked Questions
Is the Crocodile Rubber strap completely waterproof?
Yes! Unlike real leather, which degrades when exposed to moisture, our FKM rubber construction makes this strap 100% waterproof and sweat-resistant. It's perfectly suited for swimming, diving, and high-intensity workouts.
What is FKM rubber and why is it better than standard silicone?
FKM is a premium fluoroelastomer class of rubber. It is significantly denser, more durable, and highly resistant to temperature changes and chemicals compared to standard silicone. Crucially, it is anti-static, meaning it won’t attract annoying dust and lint.
Does this strap fit the Apple Watch Ultra?
Absolutely. We offer dedicated, color-matched Apple Watch adapters that seamlessly integrate this strap with all Apple Watch models, including the robust Apple Watch Ultra 1, 2, and 3.
How easy is it to change the strap on my watch?
Incredibly easy. The traditional straps feature built-in standard quick-release spring bars, meaning you can swap your strap in seconds using just your finger—no specialized watchmaking tools required.
