Hevea's deep center grooves, integrated keepers and sharply pointed tip create a distinctly sculpted look compared to most rubber dive straps. The matte caoutchouc surface stays free of added texture. It suits larger divers, modern Seikos and other heavy sport watches.

Material & feel

The strap is made from thick natural caoutchouc rubber, a durable material valued for its resistance to water, UV exposure, and common chemicals. The rubber remains dimensionally stable during regular wear and maintains flexibility across a wide range of temperatures.

The outer surface features molded grooves that run along the strap and continue across the keepers. This pattern adds grip and reinforces the technical character of the design. The underside is concave to allow air circulation against the wrist and help reduce moisture buildup. The material is tear-resistant and suitable for users with sensitive skin.
