Add a bold, technical touch to your watch with the KronoKeeper “Jules” orange and black rubber strap, a premium accessory designed for sports-watch enthusiasts looking for comfort, durability, and style. Made from FKM rubber (fluoroelastomer), this high-performance strap is known for outstanding technical properties: supple on the wrist, high density, and exceptional resistance to the harshest elements.

FKM, often used in aerospace or marine industries, stands out for its ability to withstand very high temperatures, constant humidity, and prolonged exposure to aggressive chemicals. Fully waterproof, it’s an ideal choice for diving enthusiasts, extreme sports, or simply everyday toughness.

Superior comfort and optimal ventilation

The “Jules” strap doesn’t just focus on durability: it’s also designed to deliver optimal comfort. Its inner side features specific molded channels, allowing continuous ventilation between the skin and the strap. This improves airflow, wicks away sweat, and greatly reduces irritation from prolonged wear, even during intense physical effort.

A sporty, modern design

Its look won’t go unnoticed. The textured top finish adds a contemporary, dynamic touch, while the combination of vivid orange and deep black reinforces its unmistakably sporty character. This strap is an excellent option to boldly and technically refresh the look of your automatic or smartwatch.

Compatibility and available sizes

The KronoKeeper Jules strap is available in two standard sizes (20/18-120/80 mm and 22/20-120/80 mm) to easily fit different case and spring bar widths, suitable for the vast majority of sports watches with straight lugs.

• Ideal for sports watches, dive watches, or heavy-use watches.

Choose the perfect blend of technical performance, design, and durability with the KronoKeeper Jules strap— a high-end accessory designed to enhance your watch in every situation.
