About the model

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.

About the brand

The RZE brand (originally founded as Reise) saw the light of day in 2020 and within a few short years has grown into one of the most respected microbrands on the current market. Behind its inception is Travis Tan, a commercial airline pilot and passionate outdoor enthusiast. It was his profession, where every gram of weight and absolute reliability of instruments plays a role, that defined the entire philosophy of the brand.

The DNA of the RZE brand is made of a single material: Titanium.

While most watch companies use stainless steel and reserve titanium for more expensive premium editions, RZE manufactures all its watches exclusively from titanium. Their mission is to provide "tool watches" for adventurers, athletes, and emergency service personnel that can withstand daily rough handling.

Thanks to direct sales and efficient engineering, RZE successfully debunks the myth that quality titanium watches with advanced protective layers must cost a fortune. With models such as Endeavour, Resolute, and now the digital series UTD , it proves that modern adventure watches can be technologically advanced, uniquely designed, and at the same time financially accessible.
