NOMAD Active Band Pro Apple Watch 46mm/49mm (black active leather, black hardware)

Hybrid construction

Active Band Pro uses an advanced hybrid design that combines waterproof features. skin with an inner layer made of material FKM. The skin is permanently bonded with the elastomer, allowing for a classic appearance and high functionality in demanding conditions. This combination of materials ensures versatility of use – the strap retains its structure both during physical activity and in everyday use. The inner layer of FKM is responsible for flexibility and mechanical resistance, ensuring that the construction does not deform under the influence of movement or moisture. The whole has been designed as a unified system, where each element serves a specific technical function, with no compromises between durability and aesthetics.

Waterproof Heinen leather

The applied leather has undergone a specialized tanning process that saturates its structure with natural oils. As a result, the material gains hydrophobic properties without the need for surface protective coatings. The leather not only repels water but also retains its properties when in contact with sweat or dirt, which can be easily removed without affecting the structure of the material. This process ensures the durability of waterproof properties throughout the entire cross-section of the material, not just on its surface. As a result, the strap maintains consistent performance parameters throughout its entire lifespan, regardless of the conditions in which it is used.

Inner layer FKM

The inner part of the strap is made of fluoroelastomer. FKM, a material used in environments requiring high chemical and mechanical resistance. FKM is characterized by high flexibility and structural stability, which translates into user comfort and the durability of the entire construction. Additionally, the inner surface has been equipped with a microstructure that improves contact with the skin and supports stability during wear. This material does not wear easily, even with intensive use, making it a suitable choice for solutions with elevated requirements. The use of FKM is an integral element of the construction, responsible for the functionality of the strap in dynamic usage conditions.

FKM ventilation ducts

The internal structure has been supplemented with holes that are responsible for moisture drainage and improving airflow between the strap and the skin. This solution limits the accumulation of sweat and water during use, which directly impacts comfort and wearing stability. The holes are an integral part of the FKM layer and have been designed not to weaken the structure while supporting its functionality in conditions of increased activity. As a result, the strap maintains its properties even during intense contact with moisture, and its design allows for quick cleaning by rinsing with water.

Steel elements 316

The belt is equipped with fastening elements made of stainless steel 316, including hooks and a clamp produced using metal injection molding technology. This process allows for high precision in execution and dimensional repeatability, which translates to stable fitting and durability of connections. Stainless steel 316 is characterized by its resistance to corrosion and high mechanical strength, which is significant in the context of exposure to moisture and external factors. The entire design has been created with high production tolerances in mind, which affects the aesthetics of the structural details.

Water-resistant construction

The entire strap construction has been designed to be fully waterproof. The materials used and the way they are joined allow for direct contact with water without affecting their usability. The strap can be cleaned by rinsing, which enables quick removal of dirt accumulated during use. The waterproofing encompasses both the outer and inner layers, ensuring that there is no degradation of materials due to prolonged exposure to moisture. The design has been conceived as a cohesive system, where each component retains its properties.
