Key Features
- Premium FKM Rubber Construction: Crafted from high-grade fluoroelastomer (FKM), this strap resists degradation from water, sweat, UV exposure, and temperature fluctuations. Unlike traditional silicone, FKM maintains its shape, softness, and strength over time, ensuring reliable performance through daily wear, outdoor activities, and challenging environments.
- Quick Release Spring Bar System: Equipped with built-in quick-release spring bars, this strap allows for effortless installation and removal—no tools required. Simply slide the spring bar to detach and reattach in seconds, making it easy to rotate between different straps or styles based on mood, outfit, or activity.
- Stainless Steel 316L Tang Buckle: Includes a precision-machined tang buckle made from 316L stainless steel, known for its corrosion resistance and durability. The silver finish complements the sleek design of IWC watches, providing a secure closure that maintains its appearance over time.
- Optimized Fit for IWC Models: Engineered specifically for IWC Schaffhausen Pilot and Portuguese collections, including the Big Pilot, Portuguese Chronograph, and Mark XVIII. The lug width and curvature are tailored to ensure proper alignment and a snug, OEM-like fit without gaps or movement.
- Multiple Color Options: Available in a diverse palette—Black, Light Blue, Turquoise, Yellow, Bordo, Brown, Green, Navy Blue, and Orange—this strap lets you personalize your watch to suit any style, season, or event. From understated neutrals to bold statement hues, there’s a shade for every preference.
- Tapered Design with Gradual Thickness: Features a refined profile that tapers from 4mm at the lug end to 2.5mm at the buckle, improving comfort against the wrist and enhancing the overall visual balance of the watch. The gradual thinning reduces bulk while maintaining structural integrity.

Before purchasing, please confirm your watch’s lug width (20mm, 21mm, or 22mm) to ensure a proper fit. This strap is designed exclusively for IWC Schaffhausen Pilot and Portuguese models and may not be compatible with other brands or watch lines. While FKM rubber is highly resistant to most environmental factors, prolonged exposure to harsh chemicals, solvents, or extreme heat should be avoided to preserve longevity. The package includes one FKM rubber strap and one stainless steel tang buckle. For information regarding product warranty, please refer to the included documentation or contact the seller directly.
