Premium FKM Rubber Straps In The Cut-To-Size Style. Upgrade Your Style Today.

If you haven't tried the Helvetus Cut-to-Size (CTS) rubber straps before, you haven't really experienced how a proper rubber strap should fit and feel!

While CTS straps are not new, they used to be restricted to luxury sports watches.

We believe that CTS is the best style of rubber straps, and that everyone should have the opportunity to experience it, no matter what watch you own.

Find out why we're all about the CTS strap!

Perfectly Fitted to Your Wrist
Regardless of Your Wrist Size

No matter how small or large your wrist is, our CTS straps will always fit you perfectly. You never have to worry about wearing a strap that is sized wrongly for your wrist ever again!

Sizing the strap is also easy, and you can do it from the comfort of your home—all you need is a pair of scissors and some patience!

Butterfly Deployant Clasp
Secure, Convenient, and Fun!

Every CTS rubber strap comes with a Butterfly Deployant Clasp that has a refreshing and snappy mechanism (it's not a magnet)!

Wearing your strap with a deployant clasp is not only secure (no risk of dropping your watch), it's also convenient and extremely fun with the butterfly mechanism!

Clean Look, No Excess Bulk
A now-iconic look

Unlike a traditional strap with a tang buckle that always has an "excess tail" that you tuck into the strap keepers, the CTS style means that there's no strap end, and there's also no need for strap keepers!

The result? An extremely clean look with minimal bulk on your wrist, which is quickly becoming an iconic look of our CTS straps.
