RZE HexaFlex Rubber Strap 20 mm

Give your watch reliability and style that will stand up to any terrain. The RZE HexaFlex is an iconic rubber strap designed to be the perfect companion for RZE adventure watches, as well as any other sports watch with a lug width of 20 mm.

Premium FKM rubber

Unlike common silicone straps that easily get dirty, attract dust, and lose strength over time, HexaFlex is made from fluoroelastomer (FKM). This material stands out for its high density, extreme resistance to UV radiation, salt water, chemicals, and high temperatures, while remaining incredibly pliable and pleasant to the touch.

Hardened titanium buckle

The RZE brand's DNA is also reflected in the titanium buckle, which is protected by the patented UltraHex™ surface hardening (hardness up to ~1,200 Vickers). This makes the buckle extremely light, hypoallergenic, and effectively resistant to scratches from daily wear.

Ergonomics and easy replacement

The underside of the strap features a textured surface and ventilation channels that prevent sweat from accumulating under the strap. Thanks to the integrated Quick-Release system (quick-release spring bars), you can change the look of your watch in a few seconds and completely without tools.

Key features:

• Durable FKM rubber – does not tear, does not attract dust, and maintains its shape and color over time.

• Titanium buckle with UltraHex™ coating – lightweight, extremely scratch-resistant, and suitable for sensitive skin.

• Quick-release spring bars – lightning-fast strap change anytime, anywhere.

• Ventilated structure – channels on the underside for maximum comfort even during sports and in hot weather.
