Rubber Strap
A rubber strap is a water-resistant watch strap made from rubber or silicone. It is the natural choice for sport and dive watches because it shrugs off sweat and water, wipes clean in seconds, and sits comfortably against the skin. It is also lighter than a steel bracelet. Whether you can swim or dive in it depends on the watch's own water resistance, not the strap.

Rubber straps are built for watches that live in or near water. The material does not absorb moisture or rot the way leather or fabric can, so it stays trouble-free in the pool, in the sea, and during exercise. Because it is non-breathable, it can trap sweat against the skin, so rinse it regularly to avoid odour and irritation. Most straps sold today are technically silicone or processed rubber, and both work on the same water-resistant principle.
Why sport and diving favour it
Underwater or under heavy sweat, the strap holds its shape and grip. Its practical advantages line up like this:
- Maintenance: rinses clean in seconds under a tap with mild soap
- Comfort: it does not cling to wet skin and can be fitted with extra length over a wetsuit
- Durability: corrosion-free in saltwater and lighter than steel, though standard silicone can crack or discolour from UV and skin oils within a few years, while premium FKM rubber resists this better
Paired with solid water resistance, a rubber strap is the most sensible choice for a dive watch.
Where it sits among other straps
For everyday ruggedness a NATO strap is an alternative, while a metal bracelet leans more formal. You can compare every option in the straps and bracelets category. For water-ready models to pair with one, start with our guide to the best dive watches under £500.
Examples
Sport and dive-focused watches usually ship on a strap from the rubber family, such as resin or silicone, since it copes effortlessly with constant water contact and sweat.

Comparison
A rubber strap and a steel bracelet feel very different on the same watch.
| Option A | Option B | Notes |
|---|---|---|
| Rubber strap | Steel bracelet | Rubber is trouble-free in water and sweat and stays light; steel feels more durable and suits formal wear, but it is heavier in water and needs more upkeep. |

Frequently asked questions
Is a rubber strap waterproof?
A rubber strap itself is unaffected by water, it does not absorb moisture or react to sweat. It also does not rot the way leather or fabric can. Whether you can swim or dive without removing it depends on the watch's own water resistance rating, not the strap. Because it is non-breathable, rinse it regularly to avoid trapped sweat and odour.
How do you clean a rubber strap?
Rinse a rubber strap under warm tap water with a little mild soap. For stubborn grime, scrub gently with a soft brush, rinse thoroughly, then let it air dry. Avoid solvents or abrasive cleaners, which can damage the surface over time.
Is a rubber strap or a steel bracelet better?
It depends on use. For water, sport, and diving, a rubber strap is lighter, more practical, and immune to sweat. For formal wear and a long-lasting feel, a steel bracelet wins. Many owners keep both and swap them to suit the occasion.
