Start ShoppingWhen choosing a watch for use in water sports, such as surfing and diving, it is essential to consider the most suitable material for the watch strap. Not all materials are designed to withstand the corrosive effects of salt water. In this article, we will explore the best materials for waterproof watch straps, which can be used at sea and in contact with salt water, ensuring durability and resistance without compromising the watch’s safety.
I. Stainless Steel
Stainless steel is one of the most popular and widely used materials for watch straps designed for use in aquatic environments. Stainless steel is a metal alloy composed mainly of iron, chromium and nickel. To resist corrosion caused by salt water, the use of 316L stainless steel or higher is recommended. 316L stainless steel is known for its resistance to corrosion in marine environments, making it the most durable type available for watch straps. Stainless steel straps offer excellent durability and are easy to maintain and clean, making them a safe choice for diving in the sea.

II. FKM Rubber (Fluoroelastomer)
FKM rubber, also known as Fluoroelastomer, is a standout material for watch straps that need to withstand contact with salt water. FKM rubber is highly resistant to corrosion and capable of withstanding extreme conditions. This resistance is due to the material’s special chemical composition. In addition to its durability, FKM rubber is very comfortable to wear, thanks to its flexibility and ability to mould to the wrist.
FKM rubber also offers excellent resistance to ageing, meaning it retains its physical and chemical properties over a long period, even when exposed to adverse environmental factors.
In our online store, you can find a selection of watch straps made from high-quality FKM rubber, ensuring resistance to salt water and durability. We have a variety of colours and styles to suit your preferences and the style of your watch.

III. Nylon Straps
Another option to consider is nylon fabric straps, particularly those in the NATO style. NATO-style military straps are known for their comfort and classic style. These straps are made from durable nylon, which dries quickly and is unaffected by salt water. They feature a layered construction that wraps around the back of the watch, providing a secure fit, even in extreme conditions. On our website, you can find a variety of NATO-style nylon straps, available in a range of colours and sizes. Our NATO-style straps are affordable, and we’re sure you’ll find the perfect option for your watch.

Tips and care advice after using your watch in aquatic environments
It is important to follow some guidelines and care instructions to ensure the durability and performance of your watch after exposing it to salt water:
- Rinse thoroughly after use. After exposing the watch to salt water, it is essential to rinse it with fresh water to remove any salt residue.
- Clean the watch and strap regularly. Avoid harsh or abrasive chemicals, which may damage the materials.
- Maintain the seal. Check the watch’s seal regularly to ensure it is in good condition.
- Store the watch in a dry place away from direct sunlight. Use a suitable case to prevent scratches or accidental damage.
- Regular servicing. Have the watch serviced regularly to check its performance, the seal and whether any further repairs are needed.
Conclusion
When selecting a watch for use in aquatic environments and exposure to salt water, it is important to consider the strap material. Stainless steel, FKM rubber and nylon fabric are recommended options due to their corrosion resistance, durability and safety. 316L stainless steel is the most resistant type of stainless steel and offers excellent protection against corrosion. Each material offers specific benefits, such as ease of cleaning, comfort and durability. By choosing a strap made from one of these materials, you can enjoy your water activities without any worries. Always remember to follow the manufacturer’s instructions regarding the watch’s water resistance and to look after your watch properly to ensure its longevity in aquatic environments.
