RZE HexaFlex 2.0 Rubber Strap 20 mm

Upgrade your RZE watch (and any other sports watch) to a higher level of comfort and durability. The HexaFlex 2.0 strap represents the second generation of extremely durable rubber strap, designed to handle the most demanding outdoor conditions, diving, and intensive daily wear.

Premium FKM Rubber Material

At the heart of the HexaFlex 2.0 strap is fluoroelastomer (FKM), a material significantly superior to ordinary silicone or standard rubber. FKM rubber is characterized by extraordinary density, it is velvety soft to the touch, does not absorb dust and dirt, and is highly resistant to chemicals, salt water, UV radiation, and extreme temperatures. Unlike silicone, it does not tear and does not lose its shape even after years of use.

Ergonomics and Iconic Hardened Titanium Buckle

The underside of the strap features a special textured structure with ventilation grooves that wick sweat and water away from the skin, ensuring that the strap breathes well even during hot days or strenuous physical activity.

Traditionally, the iconic solid titanium buckle is also present, treated with the patented hardened UltraHex™ coating (with hardness up to ~1200 Vickers). The buckle is extremely lightweight, hypoallergenic, and highly scratch-resistant.

Key features:

• Premium FKM rubber – maximum resistance to wear, UV radiation, and salt water; skin-friendly.

• Titanium buckle with UltraHex™ treatment – hypoallergenic, extremely lightweight, and scratch-resistant.

• Quick-Release spring bars – strap replacement takes seconds without the need for any tools.

• Ventilated underside – profiled surface prevents moisture build-up under the strap.

• Universal compatibility – ideal for RZE models and any other watches with standard lug spacing.
