Key Features
- Premium Italian Leather Construction – Made from genuine, high-grade Italian leather with a rich grain texture and subtle sheen. The light brown hue and consistent surface finish enhance the strap’s classic appeal, making it a natural match for IWC’s design ethos. The leather is selected for its durability and ability to develop a soft patina over time, adding character with regular use.
- Butterfly Deployment Clasp – Features a precision-engineered 316L stainless steel butterfly clasp, known for its dual-paddle mechanism that folds flat against the wrist. This design ensures a secure hold and prevents accidental openings, while the polished finish complements the watch’s overall appearance. The clasp’s 16mm width ensures compatibility with the specified IWC models.
- 18mm Lug Compatibility – Specifically engineered to fit watches with an 18mm distance between the lugs and a 16mm buckle opening. This precise sizing guarantees a clean, gap-free connection to the watch case, maintaining the original proportions and alignment.
- Enhanced Comfort and Fit – Incorporates a 4mm thick padded section across the main body of the strap, providing a cushioned feel that reduces pressure on the wrist. Over time, the leather naturally conforms to the shape of your wrist, improving comfort during extended wear.
- Handcrafted Detailing – Finished with brown thread stitching that matches the leather tone, reinforcing the strap’s edges and adding visual cohesion. The stitching is evenly spaced and tightly sewn, contributing to the overall durability and refined look.
- Complete Strap Assembly – Ships as a fully assembled unit, including both the leather band and the stainless steel deployment clasp. No additional parts or modifications are needed—simply attach it to your watch and wear it immediately.
