Key Features
- Curved End Design: Precision-molded to align perfectly with the Tudor Black Bay 58’s lugs and case curvature, ensuring a snug, gap-free fit that enhances both comfort and aesthetics. This tailored contour follows the natural line of the watch case, eliminating any visible gaps or awkward overhangs that can occur with generic straps.

This material retains its shape and color over time, even in harsh conditions such as saltwater exposure or intense sunlight. FKM is a high-performance elastomer commonly used in aerospace and automotive applications, chosen here for its long-term resilience and reliability.

- Stainless Steel 316L Buckle: Includes a high-quality, corrosion-resistant buckle made from marine-grade stainless steel, ensuring long-term durability and a secure closure. This buckle type is widely used in diving and marine equipment due to its ability to resist rust and pitting in salty or humid conditions.

Important Notes
This product is designed exclusively for the specified Tudor Black Bay 58 models. Please verify your watch’s reference number before purchase to ensure compatibility. The band includes a high-quality stainless steel buckle. Care should be taken during installation to avoid scratching the watch case.
