Rubber Straps

New to cut-to-size?What is a Cut-to-Size strap?Tap to learn how it works — it's easier than it sounds.

Our FKM rubber straps come oversized — you trim them to your exact wrist, then a micro-adjust deployant clasp dials in the perfect fit. The result is a strap that sits better than any off-the-shelf option.

Everything you need, included

The box includes the micro-adjust clasp, spring bars, a tool and instructions — everything to fit it yourself.

Just scissors, a few minutes

No special tools. Measure, trim, done — most people size their strap in under five minutes.

Micro-adjust clasp

The deployant clasp fine-tunes the length on the fly, so your cut doesn't need to be exact.

Cut-to-Size, answered

Is it hard to cut to size?

Not at all. You only need scissors, and most people size their strap in a few minutes. The micro-adjust clasp means your cut doesn't have to be exact — start a little long and trim to fit. See our step-by-step guide.

What's in the box?

Your FKM rubber strap, a CTS micro-adjust deployant clasp, quick-release and standard spring bars, a spring-bar tool, and printed instructions.

Once I cut it, can I make it longer again?

Cut conservatively — start a little long and trim down to fit. The micro-adjust clasp gives a range of fine adjustment, so there's room to get it just right.

Is it waterproof?

Yes. FKM rubber is fully water-resistant — shower, swim, sweat and dive with it, then rinse and go.

Integrated or Universal — which do I need?

Integrated straps are shaped to flow seamlessly into specific watch cases (check your model). Universal (straight) straps fit any watch with standard spring-bar lugs.

What lug widths and clasp colours are available?

Lug widths from 18mm to 21mm, with the micro-adjust clasp in steel — silver, yellow gold, rose gold or black.
