Blancpain x Swatch Rubber Straps

If your Scuba Fifty Fathoms ever sees water, sweat or a long hot day, this is the strap for it. A Blancpain x Swatch rubber strap is the no-nonsense choice: waterproof, comfortable, and tough enough to forget about. We make ours in FKM, the good stuff, which is what separates a strap that lasts years from one that goes sticky and sad after a summer. Here's what makes it worth it.

Why FKM, and not just any rubber

Most "rubber" straps are silicone. Ours aren't. Every Fifty Fathoms rubber strap here is FKM (fluoroelastomer), the same material high-end dive watches use, and the difference is real. It laughs off heat, chemicals, salt water and UV, so it keeps its colour and shape long after silicone would have faded or warped. The clever part is that it manages all that while staying soft and flexible, so it sits against the wrist without a hint of irritation, whether you wear it all day or take it diving. Browse the full Blancpain x Swatch straps range and FKM is the one built for water.

A shape that actually performs

There's more thought here than meets the eye. Each Blancpain x Swatch rubber strap has a ribbed texture and a gently curved, squared profile, which sounds like detail for its own sake but isn't: it grips the wrist better, lets air move underneath, and stops the strap deforming as you move. The single-band rubber Blancpain x Swatch strap flexes with you rather than fighting you, which is exactly why it lasts. If you're hard on your straps, this is the one that keeps up.

Colours and styles

Plenty to play with here. The two-tone options, black and silver, or navy and white, add a bit of personality without shouting, and the matte or satin finishes give the colours real depth. Prefer something simpler? The plain solid-colour rubber Blancpain x Swatch strap in deep black goes with everything and hides marks brilliantly, which makes it the easy daily pick. And if you want a fresher, more modern look, the blues, sky through to navy, sit beautifully against most dials.

Rubber, leather or silicone? Here's the honest take

Leather looks sharp but hates water and needs babying. Silicone is cheap and light but doesn't last. FKM rubber sits in the sweet spot: as soft as silicone but far tougher, properly waterproof, UV-proof and chemical-resistant, and a quick rinse is all the upkeep it ever needs. For a dive watch like the Fifty Fathoms, it's honestly the most sensible material you can put on it, and the premium rubber Blancpain x Swatch strap is where build quality and price meet best. Buy it once, wear it for years.

Fitting it yourself

No watchmaker needed. The Fifty Fathoms rubber strap lines up with the case's anchor points and goes on in a few minutes with a simple tool (an Allen key, often included). It's a genuinely easy job even if you've never done it before, which is handy when you want to switch between a rubber strap for the weekend and something dressier for work.

Looking after it

This is the easy part. Warm soapy water, a soft cloth, a gentle rub to lift any dirt, then rinse and let it air-dry away from direct sun. Skip the harsh chemicals and that's genuinely all an FKM Blancpain x Swatch rubber strap ever asks of you. No creams, no special products, no fuss.

Blancpain x Swatch rubber straps - FAQ

Are these rubber straps waterproof?

Completely. A Blancpain x Swatch rubber strap in FKM is built for water, so swimming, diving and other water activities are no problem. It holds its look and feel even after plenty of time in the water.

How long does a rubber strap last?

Years, typically. FKM is far more durable than silicone, shrugging off sun, salt and daily wear, so a Blancpain x Swatch strap keeps its looks and function well beyond what you'd expect.

How do I clean it?

Warm soapy water and a soft cloth, rinse with clean water, then air-dry out of direct sunlight. Avoid harsh chemicals and it'll stay like new.

Is FKM really better than silicone?

Yes. It's just as soft and comfortable but considerably tougher, more water- and heat-resistant, and it keeps its colour far longer. For a dive watch, it's the smarter buy.

Give your Scuba Fifty Fathoms an FKM rubber strap and stop thinking about your strap altogether, which, for the watch you actually wear everywhere, is rather the point.
