Why Should I Use a ZULUDIVER Rubber Strap on My Watch?

Rubber watch straps offer a huge range of benefits that make them an excellent choice for watch enthusiasts.


Firstly, rubber watch straps are highly resistant to water, making them an ideal choice for water sports, swimming, or activities that involve exposure to moisture. Unlike leather, rubber watch straps can withstand sweat, humidity, and extreme conditions without losing their shape or integrity.


This durability ensures that your watch remains functional and secure, even during rigorous physical activities.

Additionally, rubber watch straps provide exceptional comfort as they are flexible and adapt to the shape of your wrist.


This makes them particularly suitable for individuals with active lifestyles and for those who prioritise a comfortable wearing experience when selecting a new replacement watch strap. Furthermore, rubber straps are hypoallergenic, making them a sensible choice for people who suffer with sensitive skin or allergies.

Which Rubber Materials Are ZULUDIVER Watch Straps Crafted From?

At ZULUDIVER, we have carefully selected two premium rubber materials to create our watch straps: HNBR (Hydrogenated Nitrile Butadiene Rubber) and FKM (Fluoroelastomer). These materials stand out from cheaper alternatives like silicone and polyurethane due to their superior quality and performance.


Both HNBR and FKM rubber are known for their exceptional resistance to UV rays, chemicals, and extreme temperatures. This ensures that our rubber watch straps maintain their integrity and appearance even in challenging conditions. Additionally, the matte finish of these materials adds a touch of modernity and sporty sophistication to our rubber watch straps.

While both HNBR and FKM rubber are considered premium options with comparable mechanical properties, there is in fact a slight difference between the two. FKM rubber has a higher density, giving it a weighted feel and enhanced flexibility that will perfectly mould to the shape of your wrist. This unique characteristic adds a sense of quality and adaptability to our straps, making them a top choice for watch collectors.
